My CC305, ported head, 58 MM Holley T-Body, 30# injector, MAC header 93 Z has went a 12.69 @ 110 MPH the first time out with a clogged fuel filter (29 PSI on the big end), 3.6 Volts of TPS @ WOT (.19 Volts at idle)...It's supposed to be .5 @ idle /4.5 @ WOT, and 4 degrees of timing retard at 6200 RPMs.

I'm still kinda working the bugs out.

I run the Crane 210/224 cam and made 331 rwhp with a Vig3200 unlocked and Strange 12bolt. I've run 11.42 116.56 thats with stockheads na. Oh and this is a streetcar not a stock eliminater car. Frank95z

 

Good numbers frank my fuel pump is going and I believe my injectors are at almost 100% at high rpm so its time for 30#s and a 255lph pump then Im gonna run it. I still need a tune too

 

Frank, you failed to mention what the DA of that track is.


I run at 600' ABOVE sea level.

 

vance I run at a sealevel track and my best times are in cold weather. But when you're na you have wait for weather. I just recently ran 11.72 at +2550da. I think i'll run some 11.20's in cold weather at the end of the year. Frank95z

 

So how much does your car weigh?

 

I weighed 3330# when I ran 11.42. I now weigh 3180# when in race trim. Daily driver weight 3400#'s . Vance your car must be quite a bit heavier right. Frank95z

 

Hey frank did you pick up anything from the pulley and tb? I just want 11s consistant and Ill be happy

 

Man i must have been drunk when I listed my mods I didn't even remember the sig saying pulley. The underdrive pulleys were one of my first mods and i would say any performance gain was minimal. I added 52mm about the time I added headers and I think it was good for a minimal pickup maybe a couple of hundreds at most. I going to edit my mods now Frank95z

 

I was just saying those are awesome times. What gears do you have? 3.73? I have a bigger cam with a 6spd and will be putting in 4.10s and drag radials and would love to hit 11s I was at a 12.6 with a 2.3 60' so i think 11s are obtainable when I had the 4.10s and better traction

 

What about all bolt-ons, stock heads and XE 230/236?

 

Where in the 8's 1/8 is you mildly stock LT1? I ran in the 8's 1/8 with just cai and a 3.4" pulley that's about $150 in mods.

 

Frank, I assume you are trying to be funny, but I was curious as to how you are so quick.

 

He is down where the good air is....

 

i havent got chance to run my current setup, the elevation at my track is 1700 and the DA usually around 4000 this time of year. im hoping to run low 13's at 110ish on street tires and about 3800 weight including me. but i need to get a few more parts to complete the setup: 58mm TB, 255 fuel pump, #30 injectors, and some drag radials, and possibly some pullies to complete the bolt on collection
