Once again I find myself in the interesting position of having three (3) corvette motors sitting in my storage area garage with no formal plans what to do with each of them, yet, but I will.

One engine is an original 1971. It's lower half, heads, and intake all match. Intake and heads are off of it now. It will be taken down to parts soon and cleaned/inspected. It is a 350/270 base engine. I will consider a .030" bore and taking its hp up to 350.

Second engine is affectionately called my 68 Franken-motor. It is assembled using a 68 lower half, 78 heads, and an 82 aluminum intake. I will disassemble it completely down to parts soon and document what I have. This 327/350 bare block may be worth cleaning up and preparing for a rebuild. Not sure yet. Might just finish it out with new top half components and boost that power a little more to 400 hp. Might bore it, not sure yet, have to see what we have there.

Third engine is an original 1975 complete engine with matching heads and intake, dizzy, and starter. I will pull the dizzy out, pull the starter off, remove the valve covers, heads and intake and see what I have.
This engine was running when I got it. I will investigate rebuilding it and adding a new cam, heads and intake for a little bump in that base 350/165 to something closer to 300 hp. Bore .030" over and see what she can do.

All three have lots of options, share your thoughts, ideas, learnings you have from building your engines here please.

Appreciate your ideas.

Best regards,

I was down to zero here about six months ago, now I am at three. We will see where this adventure takes me next.

Seems like a lot of time and money to build three separate engines that range from 300hp/350hp/400hp. Not really a huge difference between each of them.

What is your goal in all of this? How will the engines be used? What is the point of building a 300hp engine?

AllC34Me

The object is to learn and enjoy the education along the way. These are ideas, not firm plans. Have any suggestions?

David

Yes, build a 400hp engine and a 500hp engine, then sell the one left over.

Or since its for educational sell two and buy an ls then you get to work with 2 different types of small blocks one classic one more modern

dmaxx3500

yes you have ''motors'',,,but real ''engines'' are big block chevys-396-427-454

AllC34Me

I hear you. I am building a 496/565 for the 72 road racer I have on the lift now. Going to be a lot of power. LOL.

AllC34Me

Have put together a 400 hp engine in the past. 500 hp, interesting idea.
I'll look into it.

I actually thought about that previously but have not made the plunge to try the modern stuff. My new 2017 has an LS3 350/460 engine that looks very complex, but I am awed by the power coming from the new stuff.

Worth a thought. Thank you.

I don't have homes for any of them at this point, maybe some day someone will want a nice engine for their rides. I do have a 71 that I could build into a screamer, then mount it up to a TKO and put it on the 69 chassis I have sitting here. Options are always a good thing.

Bring a wheel barrow full of cash. As you know HP costs. The difference between 400 and 500 is quite a lot in a SB

Revi

Learn? Seems like you are already there.

Just a well intentioned FYI - the "lower half" of the engine is called the short block. That is the assembled block, crank, rods, pistons etc.

Also, if your C7 has its original engine, it is an LT1 or LT4 (Z06).

jim-81

too late!

AllC34Me

LOL. Yes sir. That was my first thought, HP Costs $$$.

AllC34Me

Holy cow, do I look dumb or what. Short block I knew, just have not been using the term correctly so thank you for that.

I am brand new to the C-7 World and have much to learn. It is an LT1 matched to the MSU Eight Speed Paddle Shift Automatic. Mine is the 2LT equipment package. Have almost 250 miles on it now. LOL.

Thanks again for the help, much appreciated.

I remember my first week with a vette.

Wish you were closer David, I have an L88 427 that needs your level of detail put into it.
