engine size autocross

Soo... I'm going to be that LS guy I guess. If you are planning to AutoX the car a lot, I see no better option than the LS motor. Adding lightness to vehicles seems to be the best method for being competitive in that setting. It's hard to get much lighter than an aluminum LS engine. If you are going to be all in for the 454 SBC at $10k, I'm confident that you could piece together an LS swap for around that price. GM has a Crate LS3 430HP engine for $5k. (Granted, you may have to wait given the shortage) I'd grab a Summit Cam kit, Terminator X Max, stock loaded LS3 intake and find someone selling C6 Vette accessories. I'm sure someone makes mounts, oil pan and headers for a C3. Not sure what you are doing for a fuel system, but I ran a stock 5th gen Camaro fuel pump assembly that was modified by vaporworx that was pretty inexpensive.

There are literally a million different combinations that could be suggested for an "LS" swap, but I think this one would meet all of your goals. 2 year warranty, and not kill the bank.

Even if you aren't making the same power as the 454 SBC, you are much lighter up front and the LS motors love to rev. LS3 Vette/Camaro guys usually make 450 rwhp with H/C/I. Then if that isn't enough, swap on an LSA supercharger.
