help

Ok i have done the search thing and did not find anything I'm looking for one. what they mite have come off of. Im doing a conversion. I have a 1981 cj 5 and i bought a 1996 4.3 vortec out of a blazer. (auto) and i have read that i need to get a 153 tooth flywheel to put in it in to my stock tanny (and i know it wont hold up very long but no money) so can any one help maybe a part # or some thing that i could use.

some has to know this cum on

Try an 86-up Camaro/Firebirds with the 5-speed for the 153-tooth. Trucks are 168 exclusively. It can be VERY hard to find a 153-tooth for a one-piece rear main seal engine. Might have to go to GM or aftermarket.

Sounds odd that you can only use one particular size flywheel :confused:

Your engine block will decide if you can use a 153 or 168 tooth starter. (Starter must match flywheel) Straight-across (parallel to back of block) bolts are for 153. Diagonal bolts are for 168.

It's been a while since I mix-matched clutch/flywheels but I thought the 11" GM clutch would fit either the 153 or 168 flywheel. The 12" will only fit the 168.

Does this mean I can't replace a 153 toother and starter with a 168 toother and starter?

You can - if your block is drilled for both patterns.

Some aftermarket mini-starters *may* work with either bolt pattern on either 153 or 168 tooth flywheels. Dunno for sure though...
