Suggestions on performance upgrades for 225

The Cliffiord 4300 4v manifold is an excellent manifold. much better then the Offenhauser 4v manifold. That with a Edelbrock 500 avs makes for a good street/strip setup.

That's funny, because just about every experienced slanty runner here would
disagree w/that statement.The cliffy is a better top end runner,and the offy is more torque
friendly for the street,.... have you looked at what the OP is driving?We're not talking an RPM
needy app here,and while the AVS is a fine carb,it is still more than he'll ever use w/o other
mods.Mainly increasing valve size and cam specs,so unless he's planning to go there......
