Hey Guys,
I have a 78 Bu with a 3.0 200ci V6,I plan a V8 eventually,I believe I understand this engine is internally balanced and has the same crank flange/bolt pattern and bellhousing pattern as any average smallblock chevy,IE if I set up my T56 to fit this 3.0 It'll bolt right up and work with any internally balanced Chevy engine I can come up wiih ? Does that sound right? Let me know what you all think!! Thanks,KillerDave

You will be able to use the T5 behind the 3.3L Chevy V6. Just make sure you get the correct flywheel that will work with that engine, and your proposed V8 as well. I used a new flywheel for a 83 z28 350 . Its a lightweight flywheel. You could use something like that as well.

The 3.3- and 3.8-L V6 uses the same neutral-balance flywheel as the 2-piece rear seal V8 (excluding 400 and 454). There are standard weight and light weight flywheels in the 2-piece rear seal pattern, and they are interchangeable.

The bellhousing for the 3.3- and 3.8-L V6 is the same as for the V8.

there is no 3.0... just 3.3 200, and 3.8 229. but yes, 2 piece rms is what you need.

Hey T5.
Yea I though or kinda knew so,that's what I've always loved about GM,Chevy's in particular,all very interchangeable with the exception of the 400sb and 454 and larger bb being strokers and needing to be externally balanced,I just wanted to hear it from someone else!! I've done bought the 400dollar flywheel,I just havn't had the time to tear into it yet!! Later

Yep that's what a conversion fylywheel for an internal balanced,2 pc rear main conversion to a T56 with the back asward
pull clutch set up costs,apparently if I had a later model 1pc main engine the LT1 flywheel would have worked just fine,
Oh well such is life!! KillerDave

Hey T5,
From what I gathered on using an adapter plate you have to change to the longer Viper input shaft to compensate for the thickness of the adapter plate,besides I got everything including the master cyl,braided hose,slave and then the flywheel back,
eventhough the clutch works backward it seems like a pretty good set up as I don't remember hearing anything bad about them,
and like I said If I had the later engine I could use the LT1 flywheel,I got a pretty decent deal on it and well I didn't like the fact I had to buy an expensive flywheel it was either that or a special bellhousing as Wildman is suggesting or the adapter plate or sell this one and you can buy one for a couple grand give or take that'll slide right in there so since this one (T56) is destined to be
behind a daily driver engine (Tuned Port 267,stock 6 for now) I decided to go with the flywheel as I think it should work just fine and It kinda adds up to one of those six of one,half dozen of the other kinda deals,when you modify cars it's going to cost you money and that's really all there is to it!! Thanks for the suggestions though!! KillerDave

Yea I've got everything except time right now,hopefully I'll be able to tackle it sometime in March or April after Winter is over,I don't have a big garage but could put the 81 outside under cover for a couple weeks but I havn't had the extra energy as I'm in Truck Equipment,you know snow plows,salt spreaders and that sort of thng so when I've been getting home this season I'm done!!
Especially since Winter started about a month early!! Later,Dave
