Hy guys my engine combo is;big block 468,11.1 comp.,990rect.heads,2.25 int.1.88 exh.valves.comp.cams solid flat tappet306 629 lift260dur.at .050 th 400 trans. 4.10rear end,2'' tube headders, torker 2tm intake and 750 cfm holley carb. any suggestion can you add will be grateful. it will be to install in a 72 chevelle thanks.

maybe a newer victor jr intake. an air gap intake might work too, but not sure if it would do much good at the rpms that motor will be turning. :confused:

I agree that an intake change would help. The torquer 2 does have a very good rap. Any good single plane would help and the Vic Jr is a good choice. The 750 might be a little small also, I would think an 850 would be a better match. You will need to watch for detonation with 11 to 1 and cast iron heads, pump gas will be marginal at best.

I tbink smaller tube headers and a dual plane (like an RPM) would be best...
