Very nice.

Don't you mean Eagle crank?
Why the 4/7 swap cam?
Any reason for only a 750 carb?

Any dyno numbers?


Sorry for all the questions, just curious.

Gunmars

No dyno numbers, they had estimates but they were just taking a shot in the dark. And yes sorry it is a Eagle, mislabeled as "Scat Eagle" no idea why in my notes and receipts. Left the 4/7 swap to the shop who did the work, they left the decision to their "Olds specialist", a lot people seem to dislike that phrase but I am confident he knows what he is doing considering he built a 1100 horse Olds BB that was sitting in their show room. Carb is also a 780, again mislabeled in my notes but the box doesn't lie. I should also note that this is going to simply be a badass street car so I have no plans for slicks or racing and it will only get maybe 200 miles a year so I wanted it to have good manners.

That set up sounds mean. Curious to hear how it runs. Keep us posted.

Any pics or website of the 1100 hp bb?

Good looking Engine and I am curious how those mufflers sound, I am looking for good exhaust flow without the resonating sound. Last time I used Hemi mufflers. I think your car will have good power on the street!!

Thats what im talking about!

Silly questions, but I'm compiling parts for my 455 build. It that a chrome or a polished aluminum water pump? What kind of fuel pump are you using. Thanks, Dave

rptw32

nice build - if that's a holley mechanical fuel pump - I'd take that off
and throw it right in the trash and put a non chrome one on if you feel you
need to run a mechanical pump. I had 2 of those crack at the horizontal part of the housing coming off the block ...

for a stroker like that I'm not sure a holley mechanical will keep up with
demand if you plan on running it other than on the street .

Gunmars

I have no pics of the BBO but I am going back to the shop in a few weeks, if I remember I will get some pics and info. The water pump is chrome and I am not to worried about the pump since I never have any intention on running other than the street, it won't get anymore than 200 miles a year. Just some random car shows and short drives.

Nice job.
First suggestion, get a napa gold oil filter.....

442rocketdave

I know from your photo of your engine is far from done, but I did not see a pcv valve opening on your valve covers, just a suggestion but I did that once and I had the same oil cap you do and it blew oil all over the engine so make sure you let it breath. and a 780cfm holley is one of the best street carbs ever you can fine tune it and it will be very snappy on the street!!! Please keep us informed on your progress and let me know how you mufflers sound!!!

Gunmars

Thanks for the input. I don't think it is going to be a issue in this particular setup, the machine shop put 4 hours on the motor because of this exact concern. Did on and off test while the motor was cold and hot and a few longer duration runs and didn't run into this issue. Plus they did it for free(including fuel) to check for other issues also. So hoping it doesn't cause an issue.

Finally got it started after a small wiring issue. Here is a short video of it right after firing.

Stevec

Sounds good!

firefrost gold

looks like it has garden hoses for spark plug wires , those look huge what brand are they?
who built the engine ?

442rocketdave

Man that thing sounds strong and I love hearing that rumble that is awesome!!! You got to make a video of it going down the road once its broke in!!!

Gunmars

Scott Performance Wires. Smaller company that hand makes everything they sell.

Gunmars

Thanks. Still got more things to do like bleed brakes, Posi carrier and get the hood on and some little tedious things. Will definitely be using the GoPro for the first ride.

RetroRanger

Schnikees that engine looks and sounds pretty sweet, I like the contrasts of al, chome and gold..

If it goes half as good as it looks you should be happy!!!

442rocketdave

What Carb did you finally decide on?

Gunmars

780 prosystem

442rocketdave

Thats a very good carb! cant wait for the gopro video!!

Gunmars

Video is here. Also welcome to Pennsylvania where road work goes on all year unless it snows but the roads never get better.

442rocketdave

Nice video and I like the country side and remember they can never finish or do it to last they would be out of a job therefore Job security, work slow and do a half
*** job!! The car sounds great and that is a good way to break it in. Cant wait to hear it WOT!!

Gunmars

Worst part is I lived in the area my entire life so as far back as I remember that most roads haven't received anything except cold patch. I helped pay to get the road my driveway is on paved because it seemed like every 2 months they would come around to redo the tar and chip, that liquid asphalt is a pain to get off all vehicles let alone older cars.

442rocketdave

Its the same crap down here in Fla, they 4 laned SR44 and spent 300million on the project and two years it was completed in 2007 and they are right now repaving it!! Crazy! It doesnt have that heavy a traffic load, overweight trucks and just plain crappy work period! In Gemany when they finish a road it will last around 20 years and hold up well. I found a 69 442 on the Swiss border in 2004 and it was a convertible with only 64,000 miles they sold it for 10,400 euros!!! I have pictures! it was a solid car but a butt ugly color!! Wish I could have driven it on the Autobahn!! Anyway the roads over there are so good. Our country has alot of miles of roads and they really should do them to last!! not this crappy tar and gravel mix that breaks down in 4 years and even less up North with the Ice and salt. Our cars and our wallets pay the price for incompitence!!

Gunmars

Debating what ratio to go with for the posi carrier. With the original open carrier it easily spins the wheel when punched at any speed. Knowing this car was never made for more than just street use I was thinking about 3.08 or 3.23 to keep it as tame as possible.

70cutty

Sounds and looks great. I am planning a similar build soon. What rods did you use in yours?

442rocketdave

I have had both and the 3.23 gives a little more umph in the lower gears not much but it also runs good on the highway. My favorite all around gear is 3.42. But if your going to drive alot go with the 3.23 at least I would.

very nice

TripDeuces

That thing is pretty beastly, love it!

ThePackRat

Who knew reverse had more than 1 gear.

And props for the mad skills in driving in reverse for such a long distance like that.
