Re: 4.3 To 5.7 Swap
FYI guys chev smallblocks with a 1 piece rear main seal are not a neutral ballance .look at the engine side. you will see a pie shaped thicker area. this replaces the counter weight that was on the back end of the cranks used with a 2 piece rear main seal. check a flex plate from a small block with an automatic trans, good sized counterweight. as for motor swaps,I changed an old rinell from a 302 to a 351, went from a 13 pitch to a 17 pitch prop,4300 wot
