Many of you helped with this build up, machining help, degreeing of cam help, and of course a Harold cam.

Things wen't alright, I know there is more to be had in the tune. Here is the setup:

Holley Stealth Ram. Lunati Solid 239/247@.050 .544/.566 lift(1.6) 112LSA, Holley Commander 950, 30lb SVO Injectors, MSD 6AL/Blaster coil. Pro Topline 200cc/64cc CI Heads. 10:1CR. 3.23 Disc Rear. TH350 PDQ 3000 stall.

Car weighs 3750 w/ me and 3/4 tank.

Previous best which was the same except a comp 262 cam. 13.7@101

New best is 13.33@106.2!

This is with street tires so my 60fts are 2.0-2.2

This is with my cutout open, ran 13.6@102 with the cutout closed so I think I have some exhaust work to do.

First run was 13.9@103.3
2nd run was 13.3@106
3rd run was 13.3@105
4th run was 13.3@105
5th run was 13.6@102 (cutout cosed)

Guess after the first run I was pretty consistant!

Thanks for everyone's help! I'd like to run some 3.73 since I'm getting maybe a 1/3 of the way through 3rd gear when I cross the line. But I'm afraid I might brake the glass 10bolt. Get some street slicks and tune her a little more and there is 12's written on her. My original goal of 11's may be out of site though, oh well, she sounds good and is VERY drivable!

Thanks guys!

5 mph from a cam swap only? Very impressive.

Cam swap, and I had the engine balanced and re-ringed.
