Your car should like the 904, mine did. I changed from a 727 to a low gear 904 and it picked up 3mph in the 1/8th. The scoop will help too, especially if you seal it off with an air box. I have another low gear set cheap if you’re in the market.

This winter’s projects for me are to lose another 100 - 150 lbs, and focus on the rear suspension. Move the springs mounts into the frame rails, install 25” front spring segments, mount the shocks straight up (maybe move to the front of the axle), and sliders.

Cheers.
