Been reading up on the TR5 a little, and according to some on Moparts racing site, a SBC street tunnel ram top will bolt onto the TR5 (even though they say that Edelbrock tells them it won't) and really improve the low RPM response over the bread box plenum. The center squirters would work well, but bear in mind all four barrels open at once and there are no power valves. Great for all out performance but burn a lot of fuel. For a little more reasonable streetability, smaller vacuum secondary carbs in the 450 cfm range could be used. Most recommended carburetors by Moparts users
