Just a little miffed...

UPDATE! i havent done a compression test or leakdown, and i dont think i really need to now. im pretty sure it was indeed a tuning issue. so i sea foamed the fuel (snows flying now so itll get parked soon) and did a bit down the carb, no leaks throughout the entire exhaust, on either side. flanges, weld joints, air port hole caps in the heads, everythings solid. (id hope so since the system is 4 months old) so i found an older thread about recurving the dizzy and since mine was a "remanufactured" unit lord knows what was in it. upon tearing it down the slide plate for the advance weights was stamped L15. so 30 degrees crank advance.....hell no the slots were just a kiss over .58 inches long. i brazed the slots and filed them to .420 for 23 crank degrees. Slapped a lighter spring in place of the heavy unit (lighter spring from a 68 383 2bbl points dizzy) and i achieve 34 degrees at 2300-2400 rpm now. instead of 3100-3300. Its much more responsive off idle now, much snappier. silicone greased the bushings, filed any slag and whatnots, triple checked everything, set the vac advance can to kick in at 16 in lbs, adding 13 degrees, and plumbed into ported vacuum. slapped it all together, set at 11 static. runs like a champ! The exhaust fluttering is gone, and the power curve is more consistent now. Anything else i could possibly do besides an H pipe and tail pipes? (wich will get done) thanx guys!
