basically I've got 2 engines i designed and they are both torque monsters. one's got more peak torque than the other, but the lower torque engine has a much smoother, powerful torque curve after peak torque. what i need from you guys is your opinions on which 350 i should build given the power specs I'm posting here. FYI, i'll be using a T-56 tranny and a set of either 3.50 or 3.73 gears in the rear. with that all in mind, which of these do you think i would get better street performance out of?

...................Engine A.....................................Engine B
RPM...........Power........Torque................. Power..........Torque
2000..........177.............464................. .....175..............459
2500..........221.............465................. .....220..............462
3000..........272.............476................. .....265..............464
3500..........321.............482................. .....309..............463
4000..........354.............465................. .....350..............460
4500..........377.............439................. .....380..............443
5000..........362.............380................. .....395..............414
5500..........356.............340................. .....396..............378
6000..........317.............277................. .....382..............334
6500..........278.............224................. .....350..............283

peak hp......377 @ 4500............................396 @ 5500
peak tq......482 @ 3500............................464 @ 3000

these setups are using the stock TPI intake system, 10.50:1 compression and large valves. all ratings are at the flywheel.

as you can see, engine A has much more torque, but after the peak torque it becomes almost useless compared to engine B, which has a pretty steady torque curve at higher engine speeds. To me, engine B would be better for a daily driver because of this, the fact that it's got higher horsepower, and because i'll be using street tires i think midrange torque is more important than higher low end torque, cause i probably couldnt even hold the low end torque of engine B to the ground anyway. I just wanted to get some second opinions. what do you guys think?

 

B without a doubt would make a faster car.

HOWEVER - you'll NEVER see those RPMs or power numbers on a stock TPI intake.

 

im not planning on revving that engine over 6 grand. i think that's reasonable on a balanced 350. i mean that's not sustained engine speeds, just max.

you think i could get the same low end power if i used a larger intake, such as the stealthram? what effects do you think a larger intake manifold would have on each area of the power band? do you think the heads ahve a larger part to do with airflow velocity than the intake manifold?
