I have an idea, I'm sure someones thought of it already. The 368 and the 500 are the same block right? So I should be able to put the Eldabrock inatke and cam they make for the 500 on my 368, right? Or are the lobes to big for a 368 sense it wouldn't need as much air/fuel? Then get the heads machined and ad a high output coil on my HEI. Also I should be able to send my computer of and have it reprogramed for more performance. Also couldn't they make the computer run only 4 and 8 cylinders and skip the rough running 6 mode? I should get decent power with this set up right.
