i think they guy said it was a coan 2200-2600. i have a 351w out of my sn95 with a c-4. im installing a 393 stroker kit (flat top pistons)with world windsor sr ported heads, hooker swap headers, a 477/512 cam, and a transgo shift kit that doesnt shift until you shift it and an off raod h- pipe to 40's dumped. i currently have a e-brock performer intake (carbed) and 3.73 gears. should i buy it or wait and get a bigger stall? im probably getting a victor jr intake as well. thanks for any feedback.
