I also like the idea of HO454 crate motor by GM.
Recam it with the ZZ502 cam, a set of roller rockers...along with a 800cfm carb and your about done.
Oh yeah and EMI exhaust system too.

I'd like to see your 330 "reciepe" as well Crasyhorse. I've about settled on the competition cam, but haven't bought them yet and would still like more ideas. Also, do you guys thing we could do the pocket/bowl porting of the heads ourselves? Seems straight forward and I have all winter to putz with it.
Hope you don't mind me jumping in here mpejsa. Just working the same project as you.

blue thunder - no problem -- the more the merrier
maybe we can get our list together and compare what our outcome is? should be interesting.
I'd like to work with what i have -- but the 502 is a tempting option.
i am still gathering ideas and will post more -- when i know more.

Heres what I have done numerous times with good results. Doing another one this winter. basically everything Kaama said plus I go a little farther and have everything magnafluxed to check for cracks and I have my stock rods bushed for floating pins. Make sure the crank is straight. Inconnel exhaust valves are good insurance if youve got the cash. I also use crane gold roller rockers, their expensive but I dont believe in cutting any corners on the valve train. 3/8" chrome moly push rods too. I use trw 2399 forged pistons which have a slight dome and give good compression but not so much that if I want to "blow" the motor later, I dont have to change pistons. I use 781 or 049 large oval port heads, they are quite similar and like Kaama said, hardened seats are a must. My cam choice was based on using Gil magnum choice exhaust and to avoid reversion with the early water entry, I chose a 114 degree lobe seperation. I used Edelbrock Torker 2 cam which is a 224, 232 duration with .527, .553 lift which I advance 4 degrees. Check intake valve to piston clearance closely, it will be around .080 with this setup. I also had to use Edelbrocks Torker 2 intake manifold because of deck height clearance issues. Holley 780 and 3" by 10" flame arrestor. In years past I angle milled the heads too but dont anymore. Not saying this is the greatest setup but it works for me and my limitations. The new exhaust will be expensive but really needed for a naturally aspirated engine. You can find used pretty reasonably but make sure they are pressure tested for leaks. Good Luck and keep us posted.

Also remember when you have the trans outthat you should have it gone through if it is a merc2 transmission. Huber or Bam can do that for you. At 450 hp or better you need to take it easy with this transmission. I have the same set up in my 27 excalibur. Good luck , Forrest
