Default engine info

I have a 77 prodject car without an engine. If I get a 350 out of a wrecking yard from other than a corvette will the oil pan fit into the vette or do I have to have a corvette oil pan? Also if the wreckingyard engine cat had an electric fuel pump is the old fuel pump pad only covered by a plate or did they eliminate it in the block?

This is kind of a double posting. This was my first time posting. I put an earlier post about my engine install but couldnt find my post so I reposted and me being a dummy found my original post. Thanks for the welcome folks I hope to get some pictures of my new toy to post. I will be calling regularly on you guys for help. Thanks.

Yeah, you should be alright going with a non-vette pan. I think that they were all pretty much the same. I have seen later model blocks that have in-tank electric pumps with the provisions for a mechanical pump with just a cover over it, both small and big blocks. However, I have seen blocks that still have the mounting area for the pump cast into the block but weren't machined to put a mech pump on it, if that makes any sense. As long as there is a cover bolted on the block, you could put a mechanical pump on it. You will need to get the pump shaft though.

There's a lot more to it then just buying an engine from a junk yard. Assuming that you know that the engine is good, no knocks, cracks, or major leaks or spun bearings, once you know what vehicle it came out of you should be able to get an answer to the fuel pump cover question. GM made a couple of versions of the "350" since 1950's. Once you know what vehicle it came out of, go to a parts store and see if the can cross reference the oil pan part number from the donor vehicle to the oil pan part number of your '77. Engine mounts, manifolds, etc will also differ. As suggested, get a shop manual, you will use it more than once.

Good Luck.

I am planning on finding a compatable doner engine. I am also going to overhaul it and then installing it. It sounds like my first order is to get that aims manual. There is a swap meet in my neighborhood this weekend I plan on doing some shopping. Thanks for all the replies guys
