good sized twins for V8?

i was lookin and i looked a while back. whats some good sized garrets that would be good for my pontiac 350?8.0 comp, Bore:3.875, Stroke: 3.75, Valves 196int 1.6ex, cam will be a short duration street cam around .500 in lift. ported heads with C. chambers polished for hot spots. guess ill have to use headers since the only know turbo kit isnt in production anymore and only used ex. pipes.

edelbrock just released EFI for the bigger 389-455 engines but i figure i could make it work when it came to FI. so the efi makes things a lot less complicated for me.

thanks for any info

Maybe a GT30, they have a A/R of around 1.06 I believe and are rated for about 475hp. If you go single, if you go with twin maybe a GT25 and there A/R is .63 or so. Good luck with that monster.
