what numbers to expect?
ported LS6 heads (Trevor Johnson)- flow over 320 at .600 lift hopefully
MMT M2 cam
all the boltons and no cats
MMT had a stock 346 car with Trevor Johnson ported LS1 heads and the M2 cam make 455rwhp. According to those numbers, I can only imagine what my car will make since I have LS6 heads and 49 more cubic inches.
I am hoping for 470 when its fully broken in maybe more.
What do you expect?
I am curious as to why you did not go with an all bore setup?
Good luck with the engien build.
Alex
