Hello all, I am new to the site, but I have been lurking and reading here for a while. I have an 88 Bronco which I bought without a motor. The original motor was a 302 and i bought a 351 for it that used to reside in a 96 Bronco (not 100% sure on the 96 part..but almost). I had the 351 installed, the engine starts, the truck runs fairly well and I'm pretty satisfied with it so far, although it still needs work before I get it to where I want it to be (I don't drive it around much yet...hence, "sittingbronco").
So after this long introduction comes my question. I have read on this forum that when a truck goes from a 302 to a 351 the flywheel also needs to be replaced because they are balanced differently. I'm not sure the 351 I bought came with the flywheel. I am mechanicaly challenged so I didn't do the swap myself and that's why I don't know. However, as I stated above, the truck starts, and runs fairly well. Can anyone tell me exactly why the flywheel needs to be replaced, or what will happen if its not? Thanks in advance.
