I'm talking ragged edge, most you could get away with and how? The vehicle is about 3400 lbs, 360, 9:1, 308 heads, headers, various Holleys/AFB's to try (600, 625, 650 spreadbore, 700 DP), 727 mildly built w/3k stall, 3.55 gear. I've currently got a reground hyd. roller with 228 at .050 intake duration. I can advance it a little and dial in the mech advance on the distributor too. Would really like to try to get into the low 13's if possible. R.I.P.- Gary "Coop" Davis 02/09/68-05/13/04

Car has choppy idle and needs about 15-18 degrees of advance at idle. Runs very smooth with a victor jr(single plane) intake with Edlebrock 600 carb. I've driven it alot all over with the AC running even Vegas heat in July for hours at a time. I'm sure I could get a motor with more cam that this to run well with AC. Mine is a 727 with a Coan converter specked for my car. 3.55 gear

Do they sell an aftermarket piece for a Holley?? Also, coincidentally have an old MP 280/474 cam. It's in the 234 at .050 range IIRC. Will very likely stay dual-plane. Have an Edelbrock Performer and a Perf. RPM to choose from. I know the compressor will clear the Performer. R.I.P.- Gary "Coop" Davis 02/09/68-05/13/04
