Default best topend (pump gas)

Well, my car should be together pretty soon (after 10 months) with the LME 408 and my old LS6 heads and FMS cam. Im expecting it to make 530-540rwhp NA or so honestly.

I was thinking about going turbo or F1 but I really like the NA setup + direct port nitrous. I was wondering what topend setup on my 408 could get me 600rwhp or close on 93 octane.

My car is no longer a daily so I can live with a solid roller setup from what I know so far.

Anyone have results from ET 255s and a big cam?

Maybe you should just drive it for a while.

Damn! That's a long time! Care to share what happened?

Anyway, IMHO you would need a solid roller & either ETP 255-265 or LS7 heads

first 2 months the motor with 500 miles was at lme getting a new piston #2 and block (dunno why it screwed up, maybe injector went bad and wiseco sucks goat nuts)

next 2 months it was at inept paintshop

then for like 5 months it was at fastech where they didnt do **** and took like 3grand worth of my stuff before they went out of business (i should shoot someone)

no its been at simple quick racing for about a month (poor guys)
