I bought an 84 cutlass that supposedly has a 307 in it, (according to the VIN). Here's the problem, I pulled the engine, tore it down and did a check on cylinder size. Sure enough it mics out to be an Olds 350.

Here's the question... all the info I've found on the olds engines say they quit making the 350 in 1980. Is there a good way to tell what year it is?

And then, does anyone know if it's even worth turing this thing into a race engine?

Thanks

Ray

An olds 350 is externally different,visibly than a small block chevy, You dont have to tear one down to tell its an olds. But go for a chevy, the parts are more available and so are engines.

I know it's an olds 350. I just can't figure out what year. None of the stamps match it to one specific year. I've done some research since the first post. The casting stamp says 68-70, but the VIN derivitive says it's a 76. Olds didn't even make a 350 in 76. I'm way confused now. Any help would be appreciated.

Try checking out this website. It may help you with your questions. The 350 was made thru '80. The early 350 blocks were really good for building and they had good cranks in them. I was going to build one for a stock class. Negatives: oil control and non-adjustable valvetrain. Website: http://www.442.com/oldsfaq/oldsfaq.htm

We checked that site out, but none of the numbers on my block say it's this one. The casting number says 68-70, the stamp on the front tab says it's a 76. The F code for the nickle content is f10. This site doesn't even go to 10. So I'm confused.

What kind of oil control problems do they have?

Thanks

If im understanding correct the label says one thing and the casting number says another. It is possible that over the years the engine was switched. hope this helps.

Rookie,

I agree that the engine was switched. Olds didn't make a 350 in '84. I'm just trying to find out what year it is, or does it even matter as far as parts go?
