You have to be INSANE to have long-tube headers on a big-block A-body Mopar!

I see my suggestion got a DISAGREE. I have never worked on a big block A Body. Does that mean what works in a small block A body doesn't work with a big block? It was all I could think of. From the other posts, it looks MUCH worse than with a small block. Will those smaller starters that are available for small blocks work with big blocks?

so here's a bit of history on the 67-69 A body Barracudas. these were small cars, they only weighed around 3200 lbs. when the 67 "redesigned" Barracuda came out, engine choices were the "slant 6", the 273 small block and the 383 big block. in 68, the slant 6 was still available, so was a 318 but the 273 was replaced with the 340 small block. the 383 was still available in 68. in 69, the same engines were available, however, Chrysler sent about 345 big block 383 cars to Hurst who pulled that motor out and installed a 440. i have one of those cars which were called "M-Code Cudas." one of the reasons why Plymouth and Dodge redesigned the A body cars in 1970 was to make the cars bigger allowing for easier installation and maintenance on the 383, 440 and 426 Hemi from the factory. those cars were known as "E-body" Chrysler cars. these are the cars Mark Worman of Graveyard Carz specializes in. the 383 engine is just too big for the 67-69 A-body Plymouths and Dodges and the 440 motor has barely 1" clearance between the fender well/shock towers and the factory exhaust manifolds. in fact on the 383 and 440 driver's side factory exhaust manifold, there is a GIANT cut out area right in the middle of the downward portion of the manifold to accommodate the steering shaft of the car. the A-body Mopars were never really designed for a big block engine but true to Chrysler's "crazy engineering ideas" - they put big blocks in anyway.
