I got an 89 rs with 305ci with comp 262 cam, Holley single plane intake, 650 Holley vacumn secondarys carb, Dynomax headers w/ no cats & custom made 3" exaust, TH-350 tranny w/ stock conv. & 3.73 open diff. rear. My cars weight is roughly 3,300. Dist. is a small cap w/ vacumn advance, Bosch plugs & stock wires.



The motor is properly tuned, and runs great, I'd like to get a guess of what it would run in the 1/4th.


Oh yea and my altitude is 3,000 ft. above sea level.

 

15.5 if yer lucky
