76 400 block fitment and compatibility questions
Hi I am considering swapping a 76 400 in place of my 350 in my 71 GT-37. I have the following questions:
1) Would the 76 400 block that came with factory automatic have a boss that could be drilled and tapped for the clutch linkage on my manual transmission 71 GT-37? 2)Would my 71 bell housing bolt up to the 76 400 block? 3) I believe the register on the crank for the flywheel got smaller in 76 on the 400’s to about 2 1/2”. Is that correct? If so would it make sense to use a flywheel listed for a 76 Firebird 400? Any help would be greatly appreciated. Thanks! |
