I'd use the 340 manifolds simply because I'll bet they are lighter. (I assume)
They don't. Only the Magnum manifolds flow close to the 340 manifolds but only the '68-'70 340 manifolds. The '71 and later had a small exhaust port on the passenger side.If the truck manifolds flow equally to the 340 manifolds, would it make sense to use the truck ones and sell the 340's for $$? I imagine they have way more value than the truck manifolds. Just my 2 cents......
I think so, but I'm not after 'that' kind of flow...Is Extrude Hone still a thing?
I think so but not worth the money unless you're dumb like me. I paid over $600, 10 years ago. Wonder what it would cost today.Is Extrude Hone still a thing?
