G Body Ram Air Manifolds????
 
Does anyone have pics of a gbody with Ram Air manifolds??? I would need these to know how they fit????

No pics, Ram Air and some cheapy three tube headers are now the only option since IA closed up.

Fogot,I am borrowing a pair of long branches to mock up.Just want to see if they will work also.

Mikes455Wagon 03-05-2008 07:15 PM

Let me know for sure how the mock up goes because that could be a route I go in the very near future. Thanks.

I just bought a 455HO that was in a 84 Cutlass it had factory 69 a body ram air manifolds and the fit was very good in the cutlass

Also I hear that three tube hedmans fit. Any input on this or pics or just install information would be great. Thanks.

I have the RM-1-OS manifolds on my '78 and they fit very well. The car's in storage until May, but I can get you pictures then if you need.

I ordered the 3 tube hedmans which I have heard rumors that fit, guess we will see how that goes. If anyone knows for sure if they will of not feel free to let me know.

They will. I had them on my 80 Grand Am with the 455. There was no problem at all.

if its just going to be a street car,you can use the manifolds,but if your going for any type of performance i wouldnt use 3 tube headers they are hp killers,being i have been running a 80ga to now a 80 lemans and have gone from a 12sec 400 to a 9.90sec 505.i would try a set of headman headers for a 67 gto for the dports, if you bang the firewall alittle and i mean alittle on the drivers side and trim the rear lower control arms they will go in, i know, i,ve done it, in the jan 07 issue of hpp my car is in there with a 455 i borrowed and my old 4 tube headmans that i put back in for the dport motor
