I'm buying an engine to swap into a coupe mustang I can get either a 06-07 6.0 out of a truck or a 6.2 out of an escalade. I know the 6.2 is an aluminum block but do both have same heads and intake or no? The price difference between the 2 is like $2100 the 6.2 being more. The weight difference in the block doesn't matter to me. What heds come on a 2006 or 2007 6.0 out of a truck?

a search will do wonders, with your post count im suprised that wasnt the first thing you did...

6.2 is an l92 which is easily converted to ls3, just take off dod/afm and the vvt. the ls3 has much better heads than the 6.0...

On the 6.0 it depends which one, there is lq4(325hp) and lq9(345hp) for the trucks. On the 6.2 there is a lil over 400hp. 6.2 has the "l92 heads" which are rectangular port heads that flow more than the 6.0 317 casting heads that are cathedral port. I believe the l92 is set up for vvt which may affect what you can use for pcm and tuning. What do you plan on doing with the motor, N/A, forced induction, nitrous? Were you looking to buy used or new? If your going for new id look at the lsx376 crate motor especially if your dropping it in a fox body and have to buy all the supporting parts anyways to run it. Or just look at the for sale section and get a good price on a used one. Good luck hope this helps.

i have an ls3 and it seems to me there is a lot cooler **** out there for the ls2....such as TRICK FLOW cylinder heads...

I would get the 6.0 and spend the extra $2100 on making more power!!!!

2006 6.0 still lq4
2007 6.0 is ly6, comes with l92 rectangle port heads, same as ls3,l92
2007+ iron block l92 heads ly6 is best bang for the buck.
but lq4 usually priced way lower.

just diff. valves. not necessarily better

just shows that the grass is always greener................









ls3 owners should not feel slighted in the least. the additional bore has a secondary effect in that it unshrouds the valves for better flow.

ls3 heads are cantankerous with respect to cam selection, but offer some of the same flow of the best from the cathedral world.

loved the ls3 that I dismantled an l76 with a ls2 bottom end and replaced it with an ls3 bottom end in a pontiac g8 with 4000 miles. anyone need a ls2 shortblock???? (acronyms, confused yet?)


oh, and i stroked the ls3................

ls3 head is an entirely different casting than a ls2... ls3 has rectangular ports and the ls2 is a cathedral port like a ls1.....

edit: didnt realize he was looking at a l76 ly6 engine, should have read better, but the older 6.0 vs. a 6.2 is no question imo

People like to talk about about how great l92 and square port heads are. Yes they have great flow numbers, yes they make good power, but they are not just out shining cathedral port heads. There plenty of cars out there making great power and running awesome times with cathedral port heads.

When your talking bang for buck the square port heads are very hard to beat though.
