Can I use B or C body manifolds fore better flow on my sleeper GTS?

I think you told me that six or nine months ago it just took a while to sink in LOL
I really don’t think a 1050 annular 4150 carb was a good match for that combo.

I don’t think it would have been a problem getting the WOT operation decent....... but a good “overall” balance would have probably been a challenge.
