I believe the 3.0 uses the same bellhousing as the 2.5 2.8 3.1 3.4 etc. a company called tech pak used to make an adapter plate that would allow you to mate a BOP or multibolt 350 case to these engines. They were originally used to swap a 350 in place of a 700 R4 in S10 trucks
nope, it's the normal 1955-up Chevy V8 type bellhousing, also used on Chevy 4 and straight 6 cyl engines starting in the early 60s.
The only hitch is going to be the flexplate. That will just be a matter of figuring out the tooth count, seal style, and if it is internally or externally balanced. It is probably a derivative of a common GM unit. From digging around, it looks like they, like the V8's, went to a one-piece crank seal in the late 1980's.
looking at the picture, which I got from a GM dealer type web page, it uses the old style crank flange, so you probably just need to get generic Chevy 350 type parts. But that's just a guess.
I found this: Don't be fooled by cheaper prices. We include the distributor and ignition system with all of our new 3.0L marine longblock engines. **This engine DOES NOT require a core.** There are various changes that were made on the 3.0L engine throughout the years. The following link will ***ist you in choosing the correct longblock for you application. Technical Tips. This is a complete NEW, standard rotation long block. Includes valve cover, spark plugs, 14" flywheel, oil pan, timing cover, harmonic balancer, and circulating pump. The engine also includes an electronic distributor and coil. In 2000 GM began shipping these engines with a 14" flywheel vs. the previous 12-3/4" If you are replacing a 92 - 99 engine, you will need to reuse your 12-3/4" flywheel. Most of the engines that fall into this category will have the small rectangular port cylinder heads vs. the larger oval port head. However, this can be mis-leading since G.M. produced the oval port head during 92. You can ensure that your flywheel can be reused by identifying the following characteristics with how your existing flywheel mounts to the crankshaft: - (6) Equally spaced fasteners. - "Bolt circle" will measure 3" across If you are replacing a pre- 92 engine you will need to order product ...p/n GM181BASE_2M which includes all the additional components needed to make the newer style long block work for these older applications.
