Differences with Ram Air III D-port repo manifolds
I would like to install Ram Air III D-port manifolds in my '78 TA. There appear to be three different offerings:
1) 1968 to 1972 GTO 2) 1964 to 1967 GTO 3) 1970 Firebird The only difference I can see is usage of a two bolt/ three bolt collectors on 1) and 3) and two three bolt collectors on 2). Is there a reason why 1) or 3) is chosen over 2)? I bought a Pypes kit with two 2.5 inch flanges. Ram Air III D-port manifolds with machined 2.45" collectors seen to be scarce. eBay has some but the also charge me sales tax.. |
