LG4 VS LO3 exhaust manifolds
LG4 VS LO3 exhaust manifolds
Is there any difference in the flow of lg4 and lo3 exhaust manifolds. Can you swap one for the other? I have a friend that just replaced his manifolds for headers and I was going to port his exhaust manifolds if they will bolt on. That way my car doesn't have much down time.
Thanks for any advice

Thanks for the responce but I was aware of that much.
If they both flow about the same and both will fit I'll port the LG4 and then put it in my car. Unfortunately I have lots of time and no money.

Just and idea, but you might try to get some manifolds from a newer 350, they would flow better stock than the lg4's fully ported. I'm sure you could find them dirt cheap from a junkyard.
