Will a 6.2 flywheel fit on the back of a Gen V 454?
I dont think so...
If I remember correctly,NO other motor shares the 6.2 crank bolt pattern..its a "loner",just like a caddy..no other GM motor uses the same bolt pattern on either of them,to my knowledge..
I think I read in the diesel forum on another post that some years of 6.2's flywheels wont fit other years ,the crank bolt pattern is different,they changed it somewhere along the line..however,I'm not saying this is gospel,I could be wrong!..at any rate,a 454 will need a 454 flywheel,unless its a newer one past 1986,I know zilch about the newer stuff..they might not be externally balanced like the old ones were anymore.. ..someone here will know..
Swappin a GM Goodwrench 454 in place of a 6.2.
Pretty sure this is the motor- http://www.sdpc2000.com/catalog/123...Chevrolet-GMC-C-K-P-R-V-LE8-454N-LF8-454W.htm
Need the flywheel to fit. Anyone know the application? Could I just get a flywheel for say...an '87 1 ton with the 454?
Like this one? http://www.napaonline.com/masterpag...de=BA&PartNumber=0656008&Description=Flywheel $250!!!
The flywheel on the 454 depends if it is a 2piece rear main or a onepiece...summit has Hays flywheels fer around 230 or so..that is what I ended up getting...
I think I have a flywheel for a 454, I will check tonight if your interested
Just got the casting # from the block-
14015445...454.......78-90...2 or 4 bolt
Which means its a Gen IV 2 piece rear main seal block, and not the '90 and up 1 piece that needs a different flywheel. Jesse made a call for me today and can get a remanufactured /resurfaced flywheel for $140....but that includes a $90 core.. Guess they really want a core back! Anyways, thanks for the replies!
so buy the one for the 454 and then the next day go back and give them the flywheel for the 6.2. unless its a place you guys do business. do need to give jeese a bad name/ rep with a supplier. But if its a place like auto zone theyll never know thie differance
i said differant day cause if they happen to have both sitting there in front of them they may notice the differance...but theres also a fee for these ideas...i thinks its about 89.95
