How much HP and torque do you think I am making?
What about quarter mile times?

Some things that I took for granted are:
Compression - 10/1
valve sizes 2.02/1.95 with good flow #s
tire size- 26x8.5
red line - 6600 rpm
shift points - 6600 rpm
launch rpm - 1500
HP= about 408 @ 6000 rpm
Tq= about 388 @ 5000 rpm
1/4 mile et = 12.59
trap speed 116 mph
60' time 2.28
This is a roughish estimate using Desk Top programs. Someone else can probably get some different numbers.

Thats almost exactly the same combo that we built for my buddies chevelle,
except his is a 406, meaning it would make bunch more TQ, but the HP will
be about the same, and we didnt use 1.6 rockers.
His 406 made 440hp and 500tq, your 350 should be in the ball park with 440
HP, but I'm guessing it will make around 425tq+/-. In a all steel 70 chevelle its
run 12.0s@111, since you camaro is lighter, it should run high 11s@113+/-,
if your car is set up right and it hooks.

HP - 399 @ 6000
Tq - 388 @ 4500
With wide ratio muncie: (close is about the same)
60' - 2.34
330' - 5.69
660' - 8.48 @ 90.0 mph
1000'- 10.84
1/4 mile ET - 12.84
1/4 mile MPH - 113.2
Again with "Desk Top 2000"

Thanks guys. My guess was between mid to high 12's with traction. I'm cool with that. I will feel more compfortable when I run her at the track
My next build will be a 502, high 10's low 11's on pump gas!!!
