515ish

I was gonna say a little above 500 rwhp as well.
In all honesty, I would say around 525 rwhp is very feasable out of that combination!
Just My .02!

Either way, You'll LOVE the Instant TQ.

cadenwade

IMHO 550/500 should be a minimum with that combo. (all motor)

Subscribing.

I am building a 418 and just had Geoff@EPS spec me a cam as well. I'm hoping to make above 500 rwhp hopefully closer to 530 with a th350 and a 12 bolt.

garygnu

well over 550 hp,you will be ordering a new rear end soon if you don't break it on the dyno.why the 243s over the l92 heads?

cadenwade

Thats all i have right now.

will go ls7 heads when i can afford it.

cadenwade

o you should easy we had a 402 with that set up make 504hp

dont know the heads but if they are good, i would guess 530+rwhp through the 6 spd. rear wont last long though

cadenwade

i know the rear wont last and is next on the list just really reading the differences between the 9in and 12 bolt.

it goes up and down on the forum.

And the heads are as good as they can be there just cnc+mill 243 heads. And im sure they are going to do the job to break the 550 mark.

^^ with that motor and a M6 a 9inch is the only choice. Or a heavy s60. In for some numbers I think it will hit 550 with that 10 bolt in there.

cadenwade

well i am going to look at doing a 9in then
