How do I do this or how would you do this

Post  qtrhors1 on October 15th 2013, 10:12 pm

I want to run mid 11's on pump gas(91) in 7000 ft air(with slicks). Car weighs 3800# with driver. Has to be one 4v(holley 4150) carb auto trans and 3.25 gears. This is a car that will be driven on the street and the highway. No power adders. Now I figure a large cubic inch engine can do this. Tons of parts out there. Ive had an 11 and 12 sec SBF cars. But I want a nice driver with fun big block power. Will a stock block and a 4.3 stroke be enuff or would I need more?  Can you build a 600 hp 528 ci with 10.5-1 a hyd flat tappet cam?  I want this to be a simple and as low maintenance as possible....6000 rpm limit. Im a dreaming here?

Shocked Are you sure you don't want to pull an RV with it, too?Razz 

Seriously, with all those restrictions in 7000 ft. of air, I think your biggest hurdle (and you have a bunch of 'em) will be in getting enough air through that thing. I'd use big cubes and a big carb for starters. How rigid are all these requirements?

i think with the right parts its possible. Not a budget build though. I think you'll need at least a 557, and a good set of heads. P51 at least. A hydraulic roller would be my recommendation. You would aso need a dish piston to run pump gas. you most likely get better octane than we do here in colorado.

Laughing  I have a motorhome already so it wont need to pull an RV Smile    I know this is abit off the wall but I figure its a challenge like all the other combos we try.  I dont want a race car.
I hoping for at least high 11's.   Our local track is at 4000 ft and the the air is 5000-7000 ft on average.  91 octane is all we have.  Thanks for the responses guys.  Cool

Totaly possible, build it as big as you can.
 
Check out the build Oakley and myself did for EMC this year.

Maybe a 4.5" stroke, overbore to a minimum, camshaft that offers your expectations within your application and cylinder heads with reasonable size valves to promote good low speed performance that will support 600 hp to 700 hp, compression ratio near 9:1 (iron) or 10:1 (aluminum), carburetor in the 850 cfm range and I think you will be at your destination. 545 cubic inch at 1.1 hp/ci will arrive at your goal although I believe 1.25 hp/ci to 1.4 hp/ci is an achievable goal without enormous effort. Most of all be honest with yourself in  regard to the build, you will benefit!

Believe 1.25Hp is achievable but that's on a Dyno... But to but that to use is another thing... have seen lots of big HP not run the MPH calculation and be DOWN on power... High 11s should be very doable

Quick if you will, please do not include your reply as part of my post. Thank you, Dave.

The Dyno I have used and I hope Dave doesn't mind me saying this the same dyno he uses will show you the power that the car will run at the track.

With that being said, you can take the same engine and install it in two different cars with different people tuning the chassis and have a good ET on one and miserable results with the other.

I agree wholeheartedly with Livermore Dave
