yes the 4.3L is the L99 aka The "baby" LT1. They look identical to an LT1. Have to check the block casting to tell difference or remove head and do some measuring of the bore.

There's a 4.3 L99 motor going in to my 94Z. Bolted right in. It put down 203 rwhp on the dyno (at 10:1 afr, yeah, needed tuning).
It's now sitting on an engine stand. I'd sell it if anyone wanted it. Cheap.

So it's a corvette block with normal cast iron heads and so forth, just less bore? Or is the crank stroked different? If so, making a LT1 destroker for higher RPM would be cool!

lol Well true, you'd have to change it up to have the rev limiter raised. Low stroke = revs though. That's why Ferrai, Lambo, etc, use 10 and 12cyl 5.x L motors instead of making power the old fashion way like we do 
I kinda want a baby-LT1 now just for the block and lower end!

actually no. You're going to have to go to aftermarket fuel management, unless you consider 7200rpm a high-revving motor....

Sucks for you MAFs! lol For a stock motor, yes 7200 is high-reving.
