Thanks for the tip on the JE rings:D On the 454 rebuild last year I had trouble figureing out the shallow oil ring land on the Gen V 454 :rolleyes:

I am still not clear on the crank. I understand the Gen VI 454 and 502 crank are NOT interchangeable, but, can I use the Gen V 502 #14097044 crank in a Gen VI block?

I plan on having my machinist balance the rotating assembly.

Whats the difference between that block and a 10237292 block? I am looking into using this block with a 4.500 bore and 6.136 Crower Sportsman rods, JE pistons....

Scott B,
It is the same Block! 10237292 is the GM Part # .
10237300 is the casting # that is on the block near the bellhousing mount.

In regard to your distributor gear I would go with the new composite gear from comp cams (cheaper thru summit racing though). Many aftermarket roller cams are billet cams and have the gear drive for the distributor cut in them....they'll eat up stock distributor gears in a couple hours....and if you switch to the bronze gears you will only get 80 hours out of them before replacement is required. Just go with the new composite gears right off the bat and they'll work with any type of cam that you use now or later.

Thanks RWS! Nothing worse than having a nice box here, and then seeing a casting number that didn't match :)

We now take you back to our regularly scheduled programming..

hi Dennis i recently purchased a 95 crownline 22.5 br without an engine,it had a 7.4GL(genV) volva penta dp-s.i got everything but the long block(oil pan, v/c covers, oval port intake/w carb, harmonic balancer, flywheel and all acessories).... i cam across some internal parts i could not pass up from a GEN VI 7.4..steel crankshaft it looks to have been balanced due to stamping on counterweight,7/16 dimple rods,forged pistons,factory roller cam w/roller lifters,088square port heads,and GM square port alum.intake,less block) all for $200. the guy said it was a 2001 low rpm dyno engine from gm. i later found a low mileage GEN VI block to install all the above internals in. now the engine is in the boat and running with a different carb of course, but the engine has a viberation, i thought it was in the u joints so i removed the upper part of the outdrive along w/ujoints and its still there.i did use the balancer and flywheel from the GEN V(cast or steel crank???) on the GEN VI, with a steel crank. i had all the casting # to everything but my washer ate them any help would be great THANKS JOE

I have a stock crank and cam out of a 1999 502 that I am selling.

I have a set of 4.53 spr pistons with 10 hours and good rings. Would have to take the 502 block to 4.5 .030 over bore, but they are very nice forged pistons with low hours.

Not sure if said.
You will need a electric fuel pump, Different remote oil adapter, Flywheel.

gen v and gen 6 harmonic balancer comppatability
 

Hello, I am new to the forum and have a harmonic balancer question.
Can anyone please tell Me if a harmonic balancer part # 10216452
will work on a gen V cast crank motor?
I think that part # is for a gen VI motor but I am not sure if they are compatible.
Any and all help is greatly appreciated.
Thank you
