I say go for it! I forget what tranny an L-88 came with (think it's a Muncie M22 rock crusher) but I would go with that or, if's an auto, a turbo 400. I believe that 572 CI engine is a tall block so you will probably need to go with a new hood. Just guessing though.
.400" taller will cause interference with the brake booster and more...even if you run the low-profile valve covers... but you wouldn't want to run stamped steel rockers on that motor, and typical roller rockers require tall(er) valve covers.
Also, if you're doing a trans swap, why stick with a 4-speed Muncie...even the M22. Those have relatively crappy gear spacing. Might as well get a 5-speed. I have a Richmond 5-speed in mine and it holds with no issues. Mine is a lot tamer than this engine (mine is ~520hp flywheel).
If you want to run a super sticky tire on it, you will most certainly want to upgrade the entire rearend. Do a search on "Tom's Rearends" and you will find some nice stuff there.
Please check on the ability to fit this block in a C3 Vette. It has nothing to do with the height of the hood...that is the intake, and with an L88 hood (I put one on my car) you will have a lot of different intake choices. But the tall deck BBCs will typically NOT fit in a Vette.
But even if it doesn't... you can easily get a 502 shortblock, add some aftermarket heads, headers, decent cam (I like hydraulic rollers b/c of ease of maintenance) and you can make 600+HP easy.

I'd personally go with a 502 ramjet, there's somethign to be said about fuel injection, and that ramjet makes more than enough power to keep you happy in a nice lightweight 69 vette, I love it in a 5400 lb tahoe, I could only imagine it in something a lil more than half teh weight.

okay well that was the first stage, at least the one I'll talk about..
A 69 should handle it, I put in a 454 LS7 in a 77 Vette and used the 400 turbo that came in the car and put in a manual valve body. It was pushing around 550 hp and it would not stay in a straight line, but it was fun as hell to drive.
This is slightly off topic but my friend is redoing her Firebird and wants to put an LS1 in it, but I can't help but ask. Could she put a long block LS6 in it? I know the V8's are naturally LS1's but I'm not sure if their is enough room under the hood for the LS6.

Are you taking LS6 small block or LS6 big block? :-?
I owned a 69 for a long time. Bought it new. Anyway, taller block might cause tight exhaust/header problems. Wider spacing of intake ports on the heads could limit you on intake choices. GM might have intakd choices available but I have not checked lately. I would do the package mentioned earlier using a standard height block with selected mods. Good Luck
good catch, Rick. I was just thinking valve cover clearance, but Rick is right on. I have large 2 1/8" primary headers on my car and it is _tight_ in there. Pushing them up and out (which is what would happen with a taller deck) would screw things up, not to mention the potential intake issue.
A Ramjet will not fit without a custom hood. L88 hood? Forget about it.
You can go insanely fast without getting this 572" crate motor. You can go faster if you want, with parts that will actually fit.
