I hope Mark doesn't mind me sharing this.
Back in February I contacted Mark - cutlassefi regarding the build I have been planning for a while. My goal was 450HP BBO not more and definitely not less. My car will rarely see track so I figured 450hp would be plenty to play with. Mark told me this could be accomplished easy with parts out of box and with no porting. Today the engine went to dyno and it put out 442HP and 508 lb.tq. Needles to say Mark nailed it. Across all olds forums there has been a question about Procomp heads performance out of the box.
Here are some details about the build
Icon 886 pistons .040
Eagle rods
Lunati hyd. roller 234/242 582 lift, on 110 lsa in on 108
Bernard Mondello ProComp aluminum heads out of the box,
1.65 full roller rockers
Couple of pictures.

I also want to add that Mark is a man of his word. He was very helpful and very, very patient answering all my questions, and there was a lot of questions(some repetitive and stupid). He took time to explain everything and he got it done on time. I couldn't be happier.
The next 2 weeks are going to be the longest, waiting for it to get to me.
I can say that when I get my 66/67 next year he will be building another engine for me.

Nice, which intake and carb, and exhaust?

70cutty

70cutty

Very nice ! Mark is the man !

AK71CutlassS

very nice just ordered my rods,pistons, bearings. looking for those same numbers. how radical is that cam? mild?

AK71CutlassS

and yes Mark is a very Smart guy. Hes been giving me some info on my build as well

70cutty

The cam is not aggressive. All I can tell you is get what Mark recommends. He also did a cam for my 350 build couple of years ago and it woke up the engine.

AK71CutlassS

cant find that Cam u used anywhere do u have a PN

boese1978

Cam's from mark are custom ground to his specs.

Smitty275

Did you use the ProComp rockers also?

cutlassefi

As mentioned it's a custom grind. I think Lunati has a 234/242 grind listed but it uses different lobes than the one I did.
Smitty- no, used a Proform 1.65 Steel roller rocker. Haven't tried the Procomp ones yet, you?

Smitty275

That's why I was asking. Going to be ordering a set for evaluation this week.

jensenracing77

X2!!! I told Mark my goals and some of the parts i had planed to use and he sent me a cam that nailed what I was looking for. Only problem I have is that i have to wait at least another year till I get to drive it. I thought about installing it in another car for the summer but I sold them all.

Smitty275

I'm sure you could find a volunteer or two that would let you slide it in their ride for a test drive.

AK71CutlassS

Is it worth getting a custom grind cam like the one above ?? Im pretty Much doing the same build. And how would I get that cam?

70cutty

Talk to Mark - Cutlassefi.

70cutty

After having some issues with oil pressure and dyno breaking while the engine was on it (torque monster jk ), the engine is finally crated and on it's way. Here is the latest Dyno sheet with standard corrected numbers. I hope Mark can chime in and explain this a little further.

Temp?

chadman

LMAO! It's on there.

70cutty

It was done with cooler temps to be comparable to everybody's builds and dyno sheets.
Mark also ran it with full temp and provided me with those numbers as well, but we both agreed to be fair, these numbers should be posted.

cutlassefi

Correct, to compare apples to apples with BTR and others I provided multiple sheets. Edin also has one where it's at full temp and corrected for the crappy humid Florida air. Also notice the 1.2" of vacuum in the upper rpm range. And people say an 850 is too big for a mild 455? Not so.

Just an FYI- I've since parted ways with my original dyno guy due to various issues. This new place has a more modern dyno, a much better facility and he's one heck of a nice guy. Our dyno day last week was a total pleasure.

I hope to post more of these in the coming weeks, another EFI motor and one destined to run on E85. Should be fun!

Thanks to Edin for his patience and support. Enjoy!!!

chadman

Just for curiosity sake can you post the full temp sheet for comparison?

drjr56

570tq @3100 and 493hp @5200.....nailed it for sure.Oil pressure awesome! 133 and 134 water temp..

cutlassefi

I've tried three times to post the "at temp" dyno sheet, and the one done with corrected air for the Florida conditions but they won't load. Also tried to load the dyno video so you all can see the difference in the dyno rooms, it won't load either. If any of you think you can get them to load I'd gladly email them to you. Thanks!!

Barry Jones

Those are nice numbers ! Congratulations !

70cutty

At temp dyno sheet.

70cutty

New dyno. The old one is in one of the earlier posts.

chadman

Very interesting. I wouldn't have guessed a 40hp difference. I would have figured more like 20hp. Thanks for sharing.

70cutty

According to Mark I should be in between the two since this was adjusted for Florida weather. So your 20hp is not too far off.

70cutty

Finally the crate with the engine arrived.

It will be couple of months before I can put in the car since we just closed on a house and have to move.

Thank you Mark.

Finally all the boxes are unpacked and we are somewhat settled in the house and finally the engine is home.
Started assembling all the parts I was collecting while engine was being build.
Cutlass should be back in the garage next weekend so I can start tearing into it.
Starting the swap little sooner than I thought, the plan is to have the engine in the car and running by thanksgiving.

Magna86

I like those valve covers and air cleaner. Did Mark provide them?

70cutty

Thanks. Valve covers I bought from real57vetteguy and air filter came from Ebay. I had them engraved locally.

Should be terror on the street.
Where in San Jose are you?

70cutty

I was in West San Jose border with Campbell, just moved to Daly City couple of weeks ago, I need to update my profile here. I used to live in Union City, by Dyer and Union City blvd.

That's a bad A$$ 64 Gene.

We have a lot of folks from the Bay Area here, we should organize something and get together every now and then.

oldsmobiledave

Congrats on a fine BBO build.


After some street driving don't miss the opportunity to run it down the track. You will love the experience.

Damn thats pretty!
