Dump that E cam. those are designed for heavier cars and IMO suck for performance. Might try a custom cam from Bullet.
Also, rear end gearing has been mentioned. You'll get that seat of the pants feel of acceleration but lose some top end speed. With a small block motor, doesn't make much difference as they can wind pretty high RPM's. |
