Default what numbers to expect?

Hey guys, MMT is building me an all stroke Lunati 395 that should be done in another 7-10 days. I cant take it any longer. What kind of numbers would you expect from this setup?

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?

Kumar, I think 470 to 480 rwhp is possible depending on what rear you have and how good of a tune you get.

I am curious as to why you did not go with an all bore setup?

Good luck with the engien build.

Basically, my tuner did not feel it was worth the possible future pains for doing an all bore setup. There have been some problems with leaking sleeves etc and although those problems seem to have been solved, I just wasn't as comfortable with boring. I figure I should end up close to the same hp numbers that a lot of the MTI 422 people are getting with my 395. Also, I think I heard that a stroker is better for supporting nitrous.
