what to do? i have a 6.0l block,crank,and rods,no pistons and a new ms3 cam i bought off a friend.i would like to build this engine with this cam in mind.the heads i have are:706,317,243.i know the 243s are the heads of choice but will they work with this cam and what mod need to be done to them?oh! and what pistons?
what yr 6.0 and which version of the rods?
i would say just bore it .060 over, use lq4 speed pro replacements with rings. if it uses the pressed wrist pin rods. the pistons are round 450$ with rings.
mill the 243s, .030 a vj, with backcut valve. ls3 head gaskets.
make for a stout 375ci motor with a super victor intake and a holley 750 hp carb

Im still gettin used to the big *** cams that these motors seem to like so much! I've been messin with small block fords for the past 10 years and a .600" lift cam is race car **** in that world! Got a smokin deal on an L92 out of an 07 Escalade though so I'm takin the plunge. I went with Mahle powerpack pistons, they were $550 and they come with rings

You have to do exotic stuff to the heads and buy a race cam to make 400hp w/ a 1g sbc.but with a ls motor just a mild cam install you can make 400+ hp.a co-woker has a big inch ls pushing big block #'s.

Anytime man. this site is invaluable! Mahle makes excellent pistons. I've never used em in a car but I used to work at a shop in Friendswood TX that built high performance Detroit Diesels for big yachts and that's the only pistons we ever used! I didn't even know they had automotive applications til about a month ago.
