What exact engine

[eschaider]

The only thing you know for sure is you have a 289/302 style SBF engine. The auto trans makes me think you have a proletariate daily driver that someone put dress-up goodies on. The Holley carb might indicate some street performance mods have been made, but that is, at best, a wild-ass guess.

Chances are the only thing that might be reusable is the block — maybe. The heads appear to be proletariate daily driver production heads and should be replaced with good aftermarket heads. The rotating assembly is 99% a throwaway! A number of guys on the site have used cast crankshafts (which is probably what that engine has) with relative success. Additionally, most of the broken crankshafts you will read about on the site have been cast cranks. When a crank breaks, the damage internally is massive — much more than the premium you would have paid for the forged crank.

Your rods and pistons are almost certainly a throwaway item. Get a good set of Manley H-Beam rods and a good set of forged aftermarket pistons. Like most of the engine, the camshaft will be a throwaway. Again, getting a good aftermarket replacement is in order. The valve covers, and the air cleaner casting will look nice when they get cleaned up.

You have a lot of work and money that will need to be spent before you will have a suitable engine for your ride.


Postscript:

Before you begin buying any parts, you need to establish what you want out of the rebuilt engine and, very importantly, what budget you will assign to the project. Projects that begin w/o budgets almost always end up unfinished with a mish-mash of unwanted, unfinished, and unsaleable (at least at a price anywhere near what you paid for them) parts, and that will really piss you off the longer you own them. This is one of those, study a lot before you start (spend money) and a measure twice sort of adventures that is much bigger than it appears upon first look.
