I have rebuilt a 302 roller block to drop in my 66. I have had previous post with questions prior to the build & found good info from here.
After dropping engine in & doing up torque converter & bell housing, the engine was bound up tight, & couldn't turn it over at all. Some facts are;
Different 302W block
New 50oz flexplate (match balancer)
Same old bellhousing
Same old Torque Converter (TC)
Sandwich plate fitted
Flexplate correct way around
All bolts/drains in TC mate & fit flexplate
TC aligned with C4 oil pump (confirmed)
Snout of TC is only just protruding through flexplate.
Flexplate appears to have a different offset compared to old 28oz flexplate.
My money is the flexplate; however, allegedly they don't make one with the correct offset. I believe it is the offset of the Flexplate. I'm just trying to get lived experiences for the desired outcome.
Anyone else experienced similar, & what was the workable solution?
