244/250? Good god thats a huge cam for that little 346. My little 370 only has a 238/246

Are you sure it's a Trex cam? I thought they were a 23x/24x? I'd look for something like a 23x/23x .60x/.61x on about a 109 or 110lsa.

For an all out track car, the single plane intake will work alot better over the F.A.S.T. Its runners are short and large open plenum works in the power band of that cams advertised duration. Meaning better matched.

It can be still driven on the street. just the low end will feel non existant. 4:56s huh? running a 28" tall tire or 1/8 mile? Thats alot cam/gears and intake for a D/D.
