need help bbc

can anyone help just bought a bbc 427 for my new project bought a 29 plymouth 4 dr can you put a turbo 350 behind it? and do you have to have special torque convertor? or will it bolt to the flywheel i have on the 427?

thanks to everyone GARAGE RATS

 

A 350 turbo will bolt up to a GM th 400 flywheel. Converter size is up to the builder. Car weight and camshaft have to be considered.

 

Do not use a 400 flywheel, it has external weights and the 427 is ballanced internally, any small block or big block flywheel will work other than a 454 or 400. The 350 will bolt up .

 

Do yourself a favor and scrap the th350 and go with a th400. I dont know what your plans are for the car you are building but the th350 wont take the power output of even a mild big block, been there done that. I even went so far as to talk to a performance trans shop and was told that without several bucks a th350 wont survive. But the others are right any flexplate other than a 454 or 400 small block will fit. And if you are going to argue that the th350 has a lower 1st then the th400 you are correct but trust me a 427 wont give a hoot. Just my 2 cents worth.

 

The 350 can hold up to that 427 with no trouble....but what do I know I just build the damn things and have for 32 years. There's my Dollars worth.

 

bolts right up
a turbo 350 built by a good trans guy will hold up fine.
my trans guy has several of them in drag cars going tens
he charges me 375 a tranny.
never had a problem

 

you guys are awesome i have alot better look on things now,thank you very much to all of you this will save me some bucks and thats what i do this is my first big block so wanna do it right

heh...you guys are talking about different 400s. You can use a TH400 flywheel, as long as it's not for the heavy duty 6 bolt converter. You don't want to use a flywheel for a 400 CI small block V8, as it's balanced wrong for a 350 engine.

and if you do use a TH350, get onlychevrolets or other competent builder to put it together, with the knowlege that it's going behind a big block and needs to be strong.

 

And remember that what you need is a FLEXPLATE, there is no flywheel used with an automatic

 

good point...we just call em "wheels" gas engine older GM's have big wheels and small wheels...shop lingo for 153 and 168 tooth flexplates.
