I know you guys are probably tired of always looking at peoples posting and guessing there horsepower. Well this is my 1st time and my engine is almost done and just wanted to know an estimate of HP, maybe someone has a desktop dyno and can help out

anyways here is what i have:

350 4 bolt main .040 over and block decked and everything balanced
crank turned .010
Keith Black dish top pistons (9.5:1 with 64cc)
HP cam with .465int/.488exht .050 dur .224int .234exh
Port & polish Vortec heads 64cc with 2.02/1.60 valves
Edelbrock RPM air gap intake
Edelbrock 800cfm carb
msd ignition
double roller timing chain
custom burn chip
holley headers with "true dual" 3" exhaust

well thats about as much i can think of right now. ill keep you guys posted if i get anything else. thanks for your guys help!

 

according to dd2000 around 340 hp at the flywheel...if you give me the cam brand and name I can get closer....

 

its an elgin pro stock performance cam

also, here is a couple things i forgot about:
springs good to .550 lift
magnum 1.6 rockers
posi rear with 3.73 (i know that really doesnt matter)

 

360 hp 4000 tQ at 4000 rpm......
DD2000

I would think a little more.....

 

that sounds good i guess, i would like to make from 375-400hp

what do you think are the best way to go to get around there and what stuff do you think i need? i was thinking about returning the vortec and get the pro topline or the dart iron eagle heads. anyways i just wanted to know what i can do to get to that goal. thanks!!

 

alright this guyhas almost the exact same set up as my 406 , except his is a 350 and mine was a 400 block..how much dif does the 50 inches make?...i got iron eagle dart heads too, 215cc/64cc.

engine not in car yet..winter work in progress.

 

i'd say around 360 to 370, but what's the chip for?

 

Well I hit 375 honest flywheel hp with the same combo and little smaller cam (214/224 .442/.465")
stock unported vortecs

Haveing modded 2.02 vortecs my self now and haveing used that cam in other simular motors I'd say 400/410 hp is not out of the question.
No need to ditch the vortecs They will perform for ya.

easy 12 sec quarters with a bit of a converter and some sticky S/S tires.

Mine ran 13flat @104.5.

You may want to experiment with the cam installed position
in the motor to maximize the power curve (advance)
But other than that it should perform to your expectations.


I'm real curious about how the custom chip fit in to this too.

 

You can get a whole lot more power out of it with a better cam. That old thing is far from the best choice out there. It's akso teh Edelbrock RPM cam, if you didn't know that; it's one of those generic grinds that's been around forever.

People top 400 HP with those heads, essentially unmolested; flat top pistons; and a Comp XE268. If I was building your motor, I'd go more that direction. That will give about 10.3:1 CR with normal head gaskets that seal, not steel shim. If you want to bump it down a couple of tenths, use the Fel-Pro 1044 gasket instead of 1014.

I'd recommend not trying to do "true duals", if this is a street-driven car..... too much maze with too little cheese at the end. There's virtually no way to keep it from scraping or otherwise simply not fitting the car properly, unless you're willing to spend hourse trial-fitting bends. The negligible performance improvement, if any, and the "bragging privilege", isn't worth the hassle.

You don't need a chip. Nothing in that combo for a computer to control. You will however need a non-computer distributor.

I'd also suggest using a performance carb instead of the Edelbrock/Carter. A Holley or a Demon will work better.
