I'm thinking I may just buy a set of the Hooker Comps (2" Primaries, 3.5" Collector like the M/T's) JUST for my engine build & dyno runs. They are cheap.

I can then have a set of Super Scavengers made for the engine when I put my new engine build into a 1967 Chevelle SS (which I am still searching for).

I don't think I need the M/T's for the dyno, although that would be pretty cool! :headbang:

I'd be interested in knowing what your engine dyno'd with those M/T's however?

I always believed my '67 Chevelle L78 was in the 450HP range with my M/T Headers back in the day...based on my butt dyno! I don't think I was much off, and likely too low based on what I've learned since.
