Default Motor need a bigger cam, what to do?

My mods are listed in the signature. Obviously the cam I have is quite a bit too small to really utilize these heads. Is there any kind of range someone could suggest for them? I know it's a pretty vague question but any guidance would be appreciated. Thanks!

EDIT: Streetability is not a concern.

My car was professionally done by LG Motorsports, and I totally endorse everything Lou sells. If you want a big cam you can go with the G5X3 or the bigger G5X4 also a custom grind could be arranged. Give Bobby or Anthony a call 1-972-429-1963 to find out if you need to flycut your pistons. The X3 is good for 50-70 rwhp over stock in C5 Corvettes and the X4 is even more. X3 is more streetable, X4 is rougher. Tell them that Doug sent ya. Hope this helps.

Thats the thing, we only have 91 in CO for premium, so I have to mix up some 100 octane every tank. And no, the pistons are not flycut.

no reliefs in the pistons will be your downfall.you have the cr but with a very big cam ptv is an issue.if you have them flycut maybe the ms3 or similar might be what you want.

If you are looking for a big cam I'd look into the G5X3(or4), TRex or MS3. I would notch the pistons anyways to be on the safe side.
