I was curious exactly what was different between the two engines, bottem end, head, and manifold choices. I was considering starting off with a 2.4 head and maybe mating it to a 2.2 block to save some cash (vs the 2.4 block). If I were to 'build up' the engine at a later time what would i better off with? Are the case and oil galleys similar between the 2.2 and 2.4? And if i were to look for some more displacment and or turbocharge it, which would i be better off with. I cant afford FI to start off with. I dont have a problem with running dual webbers or a holley. Any ideas? Thanks again.
