Are the TTI's # 383440-134 1 3/4'' going to be the best pick for the 383/489 stroker i just had built for the valiant? It dyno'd at 590 hp@ 5500 with edelbrock performer rpm heads. Id like somthing bigger than the 1 3/4" tubes, but there isnt much available for the A-body. TTI's are the way to go with a small block but this is my first big block build. i did look around on big block dart, but didnt find much info.
