Best exhaust manifolds???

66cuda said

I have a set of the 340 HI-PO manifolds

Dr side - 2863553
Pass side - 2863549

AND the 318 manifolds appear the same BUT they are MUCH MUCH different and those numbers are NOT for 340 HI-PO manifolds.
just sayin

this is what 340 HI-PO manifolds look like

Yea those are nice. But it looks like they are really close on an early A-body.
I was saying that the 318 ones in 71 to 73 have the same number for the LH side as the 340 in 71 to 73. The earlier ones are as you say WAY deferent on the 340. Sure with they fit!
