with this setup.........

1983 pontiac trans am

freshly rebuilt chevy 350 block bored .30 over. holley intake and holley 650 cfm carb. 2.02 heads 1.6 valves. 480 hydraulic cam. 2800 stall. 700r4 trans with shift kit. its an automatic with overdrive. 3.73 rear end posi. hedman headers no smog no cat, flowmaster 80 series muffler. 160 degree stat. and msd coil, cap, rotor, 8.8 mm wires, and ngk spark plugs. also what kind of hosepower and torque numbers could this setup put out.

thanks for any guesses and replies.

 

I would think low 13's.

 

that sounds pretty good for a daily driver thanks, about what i expected just wanted some other opinions thanks.

 

What cylinder heads are they and what kind of compression do you have?

 

the compression is about 10:1 the cylinder heads are made of iron, not aftermarket so i dont know of a brand name if you were wanting to know if they were like vortech or something like that

 

Get it Right. By the time the boys from H.P. Racing get done building that motor for you you will be running in the mid 12's.

 

LOL no doubt 4mula88 i've got the sticker so im branded now and I will hold H.P. RACING to nothing less than 12's now so im countin on it.

 

What are the details on the Holley brand equipment? Holley makes a pretty good street but pretty poor strip intake, only good to 4800 RPMs.

I observed a 2-tenths difference between VS and DP carbs - the VS was 750 cfm, DP 650 - the 650 was quicker. Which type do you have? I made another change when I went with the Proform 750 body, going to try this week w/o the other change and see how much difference 650 vs. 750 makes.

 

Depends on the exact specs of the cam, heads, stall, and whether or not you will have traction.

Not to mention weather......

 

well finally got some times on the car last night. (the car in the sig) The 350 is still a work in progress (waiting on the machine shop) but had a great time anyways last night. It wasnt real busy so we got in about 5 runs apiece, me and 4mula88. here are my runs from first(worst) to last (best) it was my first time ever running at the track last night.

1st run
reaction... 1.188
60ft....2.298
1/4 e.t.....16.254
1/4 mph....84.58

2nd run
reaction... .861
60ft....2.307
1/4 e.t... 16.034
1/4 mph... 85.70

3rd run vs. 4mula88
reaction...1.082
60ft... 2.295
1/4 e.t... 16.010
1/4 mph... 85.58

4th run
reaction... 1.058
60ft... 2.404
1/4 e.t. 15.954
1/4 mph 86.02

5th run
reaction... .665
60ft... 2.227
1/4 e.t. 15.910
1/4 mph 86.01

so not bad for a stock crossfire motor running on a set of penskes(super k mart brand tires) with two plugs in one tire so put on the new tires and new motor and stall ill be lookin for 12's. If someone could give me a rough estimate on horspower and torque numbers with desktop dyno or somethin like that that would be most appreciated.

 

I really need to work on my launch and get those 60ft times down also my reaction times weren't that great. any tips and stuff like that would be great also

 

What kind of gears do you have in it? Looks like the crossfire is absolutely killing you up top. No matter what your 60 foot is, you still trap at the same mph and roughly the same ET. Your 5th run should have been worth a mid 15 judging by your 60 foot from your 4th run.

 

I've got 3.73 rear gear. yea thats why im gettin rid of the crossfire as soon as the 350 comes back from the machine shop.
