B/C-body Exhaust Manifolds, why won’t those work in A’s.

You don't really need to lower the weight unless you just want to. We've autocrossed an iron-headed 383/4sp '67 Barracuda. The only aluminum was the intake and radiator. Iron exhaust manifolds, as well. Jeff's Dart has (had, it's out at the moment) an all-iron 440 with an all-iron 18-spline (including the big bell and 143-tooth flywheel). The suspension is basically stock 383 A-body stuff wit modern shocks (nothing fancy) and decent tires. It's a great road car with very predictable handling.

It just so happens that I have a 67 Barracuda that I’m thinking about a budget buildup on now. It presently a 319/904/7.25. I’m thinkin a warmed up 440/727 for cost and simplicity. Just as powerful as a 451 imo and much simpler and less cost.Schumacher either way. Thanks on the manifold info. I have 2 400’s and 2 440’s.

Both. First two are my son's 440. The next two are a 383 with AC and PS in a '67 Barracuda that I sold in 2006.View attachment 1715124216 View attachment 1715124217 View attachment 1715124218 View attachment 1715124219

Looks really tight on #6 on the 440- what was the trick to getting to the wire/plug on that one?

That plug can be got two ways. The easiest (and what a lot of racers do) is to just cut into the inner fenderwell with a hole saw and come through from behind the tire. My son's car was too clean under the hood for that so we just do it cold with a box end wrench by reaching under the alternator (same with #4).
