That is good news there is another Classic olds member that has already built a 427 400G and has made over 450hp on the engine dyno.
So we have know two blocks that have tested okay for a 4" over bore.
I hope to sonic test my block this year as well.
Thanks for the update and sharing your build.

 

I have ordered off Cutlassefi
Keith Black Pistons IC744 (I think)
Big end bearings (.010")
Mains bearings (.010)
Cam bearings (STD)
Head gasket for the New Pistons.
He recommended to have the machinist deck the block to 10.600 even. That'll leave the pistons about .010 in the hole.

 

Finally some more pics of my build

 

OH yeh and its bored out to 4.00" and I should have it back in around 2 weeks depending on availability of the Engine Dyno. Dyno results will be posted.

 

Hey Rals,
I'll bypass all the heavy duty internal stuff for a few basic Q's. You mentioned you were going to get Vcover spacers. I have read on this site many of the guys have gone with thicker gaskgets instead as the spacers are $90. How are you going to deal with the alt bracket? Also what method will be used to seal the intake? rubber vs black permatex vs RTV? everyone has their own remedy but there always seems to be mixed results.
I am in the middle of installing Bernard Mondello heads/Luni Hyd cam/ performer intake with A/C so I will have to deal with the Vcovers, brackets & intake. My #'s don't match on my 69' but my wife also thinks I'm crazy as a bed bug but not cause my 442.

 

Looks great, keep us posted!!

 

HI 1918. I will contact the engine builder to ask what he will be using for the intake. We wont know if we need to go with the Alloy spacers until we install the Vcovers. I think it depends allot on what size poll locks you use on the rockers. Brackets probably will need to be modified at the time of engine install. I have access to an Engineering workshop so i shouldn't have many problems manufacturing some if need be.
I'm assuming that your doing a 400 build as well? The Mondello heads should be good. Im porting my original cast iron heads to the max

 

I went through an agonizing pro/con list and at the end of the day the hp,wt loss, cost factor and the gut feeling from Bernard steered me in his direction. All the crap you read about than Lynn dude that bought Joe Mondello scared me away from them. I'm refitting my lil red 69' so it's cumfy, fast & safe to drive.
BTW...the young lads from Perth..Tame Impala & Pond some of the best new music I've heard in ages...but how in hell could you guys loose to the UK in Rugby!!!

 

Another pic from Engine Builder. I was just thinking of the comment made about the height of the intake + Carby +_ airfilter = worried about bonnet clearance:s

 

Looking good can't wait to see how it does on the Dyno

 

I have the Ebrock torquer and 14'' aftermarket air cleaner and it has lots of room still. Car is a 69 442

 

The engine finally arrived back from the shop after 6 months. I was a little disappointed in the engine builder (fataz) as i thought his communication through out the build was less than impressive. It seemed that the only time I received any communication from him was when he wanted a part that he couldn't source here or when he wanted some money. I found Fataz after seeing via google that he had many good recommendations and that he builds engines for and races on the Australian Trans Am championship circuit. Lots of experience I thought. After spending a considerable amount of money I expected some advice along the way on what he would recommend to achieve the gains in HP that I was after, "Nothing". I sourced my parts from "cutlassefi" who I found to be most helpful. Fataz basically took the parts whacked them on the engine, did a few minor mods, (bore the cylinders, supposedly port the heads, balance the rotating assembly) and here you go heres your engine. NO info on how to run inn the engine, no phone call to see how the engine is performing, nothing. The Blue print sheet (which I will post) was an absolute mess and the dyno was disappointing. I have previously in this thread posted the specs of this build. I would have thought that I would have gained more HP than what I did. I think I have restricted my HP gain by keeping the Exhaust manifold stock (on a twin 2.5" X over exhaust) and keeping the Rochester stock as well. Maybe I'm being a little harsh on Fataz, you tell me if I am. I don't know.

 

Sorry to hear about all your problems ,you did do all your homework with the research for the motor and to me your engine builder dropped the ball, sounds like he just wanted to get you out the door and get the money in the bank.The builders dyno may be conservative but you'll have to see how it performs once it's in the car it may be good.If not then he'll have to make it right for you.JMO
Good luck

 

Thanks mate. We will see. I need to get it up on a chassis dyno and tune it correctly. Ill let you know what happens.

 

Video link of the before and after. Can you tell which one is before and after??

 

Second video is the rebuild...and it sounds good.

 

X2 second video.
How many pulls on the dyno?
Maybe the rings have not completely seated yet?
You left some on the table with stock exhaust manifolds and a stock Qjet.
There should be more in it after it is run in and after tuning I would think.
Do you have any pictures of the head work that he did?
Thanks for sharing your build and good luck with it, enjoy.

 

Your only real performance mods are the large over bore, roller cam and any head work that has been done. I see the heads were not filled on the heat riser cross over

 

Thats correct Bernhard. No cross over filling done, and he didn't supply any pics of the head work I just checked the Carburetor ID # (7043250 RA 1574) and it comes up as a 1974 350 olds engine carby. I bought it on evil bay from i5autoroca. Because I didn't need it until now stupid me didn't check to see it was the correct carby (for a 455) liike he advertised. I guess that is probably contributing to my low HP.

 

You"ll want to see what jets and rods are in that carb cuz if it was rebuilt as a 73 carb it'll be to lean for your motor , I have the same carb on my 350 and I'm using 70 jets with 44B primary rods and it runs nicely after it's warmed up. Don't want to hurt your pistons by running lean or run too hot either . jMO (74 carb is probably similar to 73)

 

Mines a stock 350 BTW

 

With a 4''bore, fully ported heads,that cam,and making sure the carb and timing is right why would this build not make over 400hp,and 500+tq besides the exhaust manifolds holding it back..I'm wondering myself.I opted to put a 455 build in my 69,used procomp heads, hd roller,with a 750 holley on a Performer.I think I'm over 400/500. Maybe the aluminums are that much better than fully ported irons,are we sure they were really ported.

 

another 69 442 400 ci bored to 4" stock flat top pistons/Bernard Mondello pro comp heads/ everything roller from Howard I219@.050 E229@.050/ performer intake/QFT 750 & 1"plastic spacer best:505ftlb@3400 415hp@4800

 

Evidence

 

BTW...Rals, I have a never used "stage 3" Qjet with the inline tube new fuel line from carb to pump. Happy to make a deal. send me a PM....on my build I used ARH stainless, everyone says that's the cats *** of headers. The dyno guy put a bung in the collector to measure A/F

 

Good numbers and I believe them.

Ralf- the car sounds nice.
But for comparison I have a stock, big valve Ga headed .040 over 455 in my shop. I posted it on here. 413hp/497tq with Flowtech headers, an 850, RPM and 231/234 hyd roller.
I think you have at least 30-40 on the table vs the ARH's 400 listed here. Plus without visual verification you don't how extensive your port job was.
My point? I'm doing an EFI'd 455 for someone who paid 1K for port work on Edelbrock heads and intake. They simply cleaned them up with a cartridge wheel, no real metal was removed, anywhere.

Additionally I think as we move forward, we are all realizing that the stock heads are a waste of time. I understand why some use them but there's no doubt they hinder performance unless extensively ported.

Best of luck.

 

Hey Cutlassefi, I sent you a PM bout a month or so ago & never got a reply...

 

Really? Sorry, I guess I missed it. How can I help?

 

Wow a grand just to cleanup aluminum heads...what would justify doing that,would a little bigger cam benifit from it??

 

I don't want to bogart this thread, Cutlassefi if you want to start another thread. If you look at the picture below. I would like to know if I can put a 12 gauge wire from the relay on the firewall (behind the booster which I removed) direct to my new DUI distributor....

 

Basically he got ripped off.
I'm not saying fataz ripped Raisy off, but my point is different people may have different ideas about a "port" job. Hopefully Raisys was done right.

 

Any good switched 12v source is fine. You don't necessarily have to use a relay. Just make sure your switched 12v source is operative during cranking as well.

 

I will have a look and see what primary rods and jets I have. I will also ask Fataz if he has any figures on head flo.

 

I don't think you will know the true potential of your build with out a set of quality headers and the Qjet set up for your build.
Your car looks Sweet in the Video
Thanks again for sharing your build

 

Your right again Bernhard. I need some block huggers. Hopefully when I take the car for the chassis dyno on monday I will have more of an oversight on what I need to do with the carburetor.

 

I went for a chassis dyno today and here are the results. The before engine rebuild and after engine rebuild.

 

So I have gained 11 HP for a total cost of $1000 per HP. You have got to be kidding me. What the heck?

 

In hindsight I should have had Cutlassefi build me an engine and send it over here. It would have been cheaper.

 

And better.

 

Ralf, I think we can all say we've been in your shoes before , where we've paid for services that weren't delivered.This guy Fataz should make things right with you if he's any kind of a professional .Good luck mate ,hope it gets better for you somehow.
