Question
I have a 1989 chevy subberben. it had 359 small block which blew. im know runnining a 454 big block. the origanal transmision is a 700r which isburnt i have no drive and no overdrive. what would be the corect transmision to bolt up to the 454. also the subberban is a 4 wheel drive. thanx for any help.
This is a much newer vehicle than I am used to working on, so take this advice with that in mind. The only automatic I would put behind a 454 is a Turbo-Hydro 400 - those were what was used when the engine first came out, and it can take the torque of a big block - The 700R4 was at its limit with the 350.
Put your question to some of the other guys on this service that have more experience with modern vehicles - you might get a different answer.
If your Suburban had been a 1935 year model, I'd have been much more comfortable answering your question. (Didn't know they had them back then, did you?)

Expertise
I can help on most American passenger cars built between 1930 and 1970, and Imperials through 1983. I have over 50 years experience in restoring and maintaining antique and classic cars, including 20 years operating a classic car repair shop. I am now retired, but I am willing to help with any questions of a technical or mechanical nature. I have more experience with Packard, Studebaker, Hudson, Imperial and other luxury makes, but I do have reference material and experience with most makes.
I do not know anything about modifying cars - if that is what you want to know about, pick someone else. I keep them the way the factory built them, and I advise you to do the same, to maintain the value of the car and also for your safety.
