I've come into an engine I'm having trouble identifying or at least finding more out about. Any info or light would be appreciated, I think it is an 81 or 82 Buick, has distrubitor in the front, casting numbers, block 25514291, heads 25506293s has a 2V Rochester. This engine was a transplant into a Jeep and the block is cracked. My questions are , do the later V6's have the same bellhousing pattern, and are the heads interchangeable. Thanks, Patrick
Starting in '64, the rear drive Buick V6 engines had what's commonly called BOP (buick-olds-pontiac) bellhousing pattern. those engines ranged from 225 cu in to 231 cu in and on to 252 cu in. there were rear drive Buick V6's in '61-'63 but they were 196 or 198 cu in (loss of memory is a terrible thing) and had the same bellhousing pattern as the 215 cube aluminum V8's of the period. Later front drive Buick 231's (3.8 litre) have the same pattern as most other GM front drive engines but will accept a 700R4 from camaro and S-10 4 & V6 (60*) engines and presumably, stick shift bellhousings from the same. Don't know about flywheel applications for the Buick in that instance. Ray
Not really sure how to identify the motor short of taking off the head and measuring the bore which should be 3.965 inches. I have no idea what the casting numbers would be but from the outside since the 3.8 and the 4.1 are identical on the outside. I believe the deck height is the same on both motors. The 4.3 is an entirely different motor from the 4.1, the 4.3 is derived from the sbc.
BUICKS RULE!!!!!!!!! actually, they are great engines that are often underrated by rodders because they are not 8 cylinders........ I began installing them in Jap pickups in 1970.......the largest cu in engine that actually would fit in the space available and made my Datsun pickup fly! In those days, hardly anyone was doing anything with the little trucks, especially in the midwest. I had LOTS of fun surprising drivers of all kinds of vehicles. I built four trucks over a ten year span, each a little better than the last. My final such project was an '80 Datsun (Nissan) with a factory turbocharged 3.8 V6, the 350 turbohydramatic it came with and a 3.70 (i think) third member from an 810 Datsun sedan in the truck housing. California step side box, mags and fat tires, Z-28 buckets, the console from the Regal the engine/trans came from. All very nicely blended into a very satisfying ride. By '84 Nissan was building V6 pickups and it was no longer necessary to build my own and I moved on to other projects. The current available factory supercharged 3.8 would be a good rod engine for the right car.........'41 Willys Coupe maybe??? Ray
Being a Buick mechanic, i would absloutly LOVE to see some picws of this Buick powered minitruck of yours. I have been seriously contemplating a 3.8 powered A-Pick Up.
