Since I have an early A body I have been stuck with a Clifford header. While it is a vast improvement over a stock exhaust manifold, I feel the Clifford does leave a lot to be desired since it is mainly designed for fit and not function.

I have a set of Spitfire step headers on the way and hopefully will be able to provide some dyno numbers on them vs. the Cliffords.

On the later A bodies my favorite pipe was the Mopar Performance/J&R header, but it too is a crapshoot as to whether it will fit your car or not. They still turn up for sale now and then.

A Super 6 is a good upgrade IF you get a good carb. Problem is that most of the BBD's still in existence have the throttle shafts worn out and leak vacuum like a sieve causing all sorts of issues.

My personal favorite is still an Offy intake and a 390 vacuum secondary Holley, but that's just me.

Have you done anything with your distributor? A stock distributor has so much mechanical advance it is almost impossible to get enough initial timing into them without pinging under load. Welding in the advance slots about half way and putting in lots more lead may help.



when u say A body, do u mean the cab over trucks and vans?if so, r u saying only Clifford headers will fit inside the doghouse?

i have an A van. this could be crucial info for my project.

many years ago, i saw a single(6 to 1) header that made the starter almost impossible to remove. i like the idea of the dual headers a whole lot better.

it's fairly easy to find info on the clifford headers, not so with other brands.

who else is making them, which will fit an A van, and what /where r the details on the ones that are beeing offered in this forum?

D~~~!

Me too... it's the breaking and fixing part that I don't like.
