The TTI's for the big block A body are only 1 3/4" diameter & came w/ huge dents for clearance.
Expensive w/ ceramic & thermal barrier coatings & I have the up for sale. May post them on ebay next week. Built a 451 stroker for my 383 4 spd formula S, so going to larger B body headers.
www.bigblockdart has an article in the tech archives about B body headers in a 383 A body.




BBD is where I got my info
