Ok I have an 82' el-camino with a 79' sbc 350 4 bolt main,2 piece rear main, staggered bolt pattern starter.
I have pulled the old block with casting # 3970010. Swapped with another block with the same casting. We also used the same starter
and flex plate from first engine. Now we have very noisy engagement of starter to flex plate. If we add a shim it no longer makes contact
with the flex plate. Starter needs to mount closer to the flex plate. I have now tried new 3510 gm starter and a mini high torque one as well.
Same issue across the board. looking for any ideas or suggestions to resolve this. thank you again in advance.
