    My 73 came with the inline 6, so I guess the t14 was stock in that JEEP? Explains why mine had a 8 1/2 stickout. I'm slow, but i'm catching on.
    Probably have to do less floor pan mods with the t15, than one of the 4 speeds. Its looking more and more like, 231, t15, d18.

    Yes. If the T-15 is the same stickout, that indicates it's from a '72-75 304 CJ or '72-73 304 Commando, or from a '76-79 Wagon/J-truck with the 258.

    I'm trying to learn a little about it. The large fitting on the rear of the intake man, does that have something to do with the air pump circuit. It wont have an air pump in the 3b.
    Pulled the oil pan and found rod and main bearings had been replaced, and look to be in good shape. Bought this engine from a member here and looks good so far.

    The slotted opening is for the EGR for sure, but the one just to the right. EGR also??

    I am looking for a flywheel for the 231 v6. would this one work, or is there a better option, without excessive cash involved?
    More Information for LUK LFW131
    Its fits a 1980 El Camino. I'm sure I would have to use the correct starter because of tooth count.

    I think that some catalogs list 1980-84 3.8 liter for the Chevy 229 engine. If it has 7 crankshaft holes it will not fit.

    The intake in the pic is a 231 unit. Giveaways are the egr valve mount S noted and the pcv valve hole in the right rear of the intake. They can work on a 225 if using the right FelPro gaskets.
    Most of the El-Camino flywheels I've had used a 9 1/2" clutch. Not optimum for a Jeep application but can work. The Jeep and Monza applications I've run into used a better 10 1/2" clutch assemby. My 231 is from a 1980 Monza and uses the 10 1/2" clutch assembly. Under hard use the stock clutch is marginal which is why I upgraded to a heavier duty unit (Borg-Warner Super Brute). Not sure that unit is still available but there are other options like Centerforce out there.

    All Buick engines are externally balanced. A good shop can rebalance your odd fire flywheel. The engine can stay buttoned up.

    I hate to disagree with the statement that a good machine shop can balance an odd fire flywheel to even fire spec's if they don't have the spec's and or all of the moving parts. Even if you were to invest in the Centerforce flywheel it is balanced for an internal balanced forged crankshaft. So you would still have to get it balanced for your stock even fire engine. Aftermarket rotating assemblies with forged cranks are usually internally balanced. All production Buick V6 cast-iron crankshafts are externally balanced. The unbalance factor for 1977-and-earlier odd-fire Buick V6s is different than the factor for 1978–1987 even-fire Buick V6 engines. According to TA Performance, the even-fire production unbalance factor is 36.6 percent.

    Perhaps I missed the "Good Shop" and still a little bitter about the work done on my chevy 383 stroker engine. I called my local shop he said he would need all the moving parts to balance the flywheel. Cost per hour deal approximate cost $250.

    I bought this flywheel from RockAuto and it will not fit my 231 evenfire. 100% sure. I think I will try the oddfire flywheel and see what happens.
    Anybody done this??
