It's been about a year and half since I first ran this on the dyno.

I've had a bit of time for revisions since someone rear ended me at 40mph on the way home. Car is all fixed and completely repainted now, better than ever.

Basic combo is-

.060 over 426 so about 438ci.

MP iron block, CP pistons, 12.4-1 .043 rings. GZ vacuum pump

MP iron heads (I ported them)

Cam motion low lash solid roller 262/262 112lsa, .658 .612 measured at the valve. Morel black mamba lifters. Trend tapered pushrods. PSI 1.4" OD valvesprings with TI locks and retainers.

Holley HP efi. Edelbrock dual 4 intake, ported. 80lb deka injectors, Flex fuel

TTi 2.125 headers into dual 3" exhaust, pypes race pro mufflers out to stock style tips.



So here were the revisions between the overlayed graphs.

Added HVH 1/2" spacers under the throttle bodies

Changed stock diameter lower pulley to ASP underdrive (it was blowing belts into low earth orbit) Way too much pulley ratio for the rpm.

Switched from 20w-50 Brad Penn to 5w-30 Royal Purple XPR. Also changed to synthetic trans and diff fluid.

Rebuilt tailpipes (they got smashed) with the largest radius bends I could fit.

Last thing that I'm sure made a difference to the results was removing 15x10 steel wheels and replaced with W23-ish 15x10 aluminum wheels.

Made quite a difference! Feels awesome on the street.
