What will it run? Any guesses?

When I got the car, all stock, with 2.73' open rear, and no tune up ever it looked like, the car ran 15.5 in the 1/4.

 

any guesses??

 

I dont think so, with the "stock" cam, and the #28 injectors. When you say "custom' prom, is that an eprom you will be tuning yourself, or one that will be purchased through mail order? Youll be throwing away your money with the mail order proms. Anyway that still is too much injector IMO.

With #24 injectors, a better cam, and a good tune, along with a 2600 to 2800 stall converter, I think you might accomplish your low 8s in the 1/8th, or mid to high 12s in the 1/4, with good traction.

 

Too much injector, really? The prom was burned for me by another member. I was thinking about putting a bigger cam in, but I am going to build a new short block in the near future anyway, so wasn't sure if I wanted to go trough the trouble.

What if I hit it with a 150 shot?

 

Well now, a 150 shot is a whole different approach. If you can get your combo to go 13.00s, a 150 shot should put you in the 11.70 range. I have a few friends that did this. Their 13.00 N/A run, usually netted them 11.70s on the juice. This was with S/R equipped 350s.

 

 

It took a hotcam to get me a 8.1x 1/8 miles with everything else being similar.

firedawg, next time just post up heads, cam, intake, and cubes. Lets keep it simple.

 

Sorry the only reason i did that was ET aren't just about motor. It's all about suspension, motor, tranny, rear end gears, and even weight reduction. If the car won't hook up the car will be slower, motor has no power it takes longer to go down the track, auto/manual makes a different, rear end gears lower higher gears can change how fast you accelerate or faster you go, and also less weight means less weight for the motor and everything else to move.
