it's little ford ranger w/308 cid - dart pro 1 heads -10 to 1 comp. cam is a trick flow stage III - I don't know the specs on it. its a Hdy.roller- it has a single plane Parker intake. 650 pro form carb. jets are squared @ 68, it has a msd 6AL. Timing @ 38 deg. #7 ngk plugs and he runs 93 oct. fuel It weights 2900# it has a 430 gear and a Turbo 350 with a 3000 stall he foot brakes out at 2600 it has 10.5 x 28'' Tires. now when he stages it sounds good but as soon as he hits it it stumbles about 20 feet then it cleans up and runs great. we rejeted to 65 and no change. we didn't have a chance to do anymore testing because of track problems. any advice would be help full.
