I think I've probably hit the wall with my setup.
357w
10/1
vic jr./modified 650
69 ported w heads 194/1.6
ultradyne 243/247 571/582 108lc 102ic
c4 coan 3800 stall
4.56/28" tireafter changing cams this winter and getting rid of my gear drive I've went from 11.80's to 11.60's @114mph. Would a set of aftermarket iron make more sense of would aluminum work (pro-topline,dart,rpm's,afr).Which one do you like best for this motor? Also what do you think I would pick-up in 1/4
thanks
Mark

A buddy of mine ran 11 ohs with ported '70 heads and a hydro cam. I think there's more in your combo. A looser convertor would help, especially with that cam.

A Holley 750 dp'r is the right prescription for what ail's you.  SteveW p.s. If you swap heads I'd go for the Vic Jr's.
