I'm in a quandry and perhaps member(s) can set me straight. I am building a 69
L/71 ( 427-435hp ) engine back to its former glory. I am currently on the
crankshaft portion of the project. Here's where the fun starts. What is the
correct crankshaft for this 427? I have several 396's that used the 3856223
forged crank. 4-bolt variants were cross-drilled & tufftrided. What were the
corresponding crankshafts for the 427-400hp, 427-425hp, 427-435hp, L-88 & ZL/1?
I have seen too many '6223 cranks on ebay that sellers claim were 396/427
crankshafts. But, acording to Alan Colvin's book, the 396 & 427 crankshafts
were different in that the width of the counter weights were different.
Evidently due to the differences in piston weights of the 396 & 427. What is
the truth? I was actually hunting the coveted '7115 crankshaft for this engine,
but perhaps that is an L/88 - ZL/1 crank only. Currently on ebay there is an
L/88 crate engine ( reported to be ) that has the '6223 crank. What gives?!!!
Did 1969 4-bolt main 427 engines use the '7115 crank and/or the '6223 crank?
HELP !!!!!!!!!!!
