Split Y pipe

Could the pipe split as a result of a backfire? The 79 350 I got had oil diluted with gasoline and some inexperienced kids had previously tried to get it started. The donor truck was later scrapped due to severe rust.

It has a TH400 attached. I am wondering what is the minimum I have to do to ensure it is OK. Put some oil in and do a compression check? Remove trans and put in new T/C seal? Pull engine pan for a look and put in front and rear seals and new timing set?

I will be putting in a quadrajet carb kit and having a look at the distributor that seems a little stiff to turn.

Opinions welcome.

Re: Split Y pipe

Plugs will give you an idea of the overall condition. Puling a valve cover tells you how well it was taken care of. Nice and clean and we may have something, full of gunk we have one that may need a rebuild. With gas in the oil I would pull the pan. Never know what shape the bottom end is in. Any time I buy a non running engine I just assume its a core.

Re: Split Y pipe

The price was right in that I just had to pull them out. They got transported in the back of a VW Golf sportwagon on a cut down pallet.

The plugs must have been good because I was told they were previously swapped out to a different engine.

In the car

I did some phoning and found out the split Y pipe was not even from this engine as it used to have dual exhaust. Regardless i'll take PGSigns advice and tear it down for an overhaul.
