Im new to this forum.. and new to the LS world. Basically, I am on a budget build due to the fact im hunting for a house soon.. so I need some ideas of current power/ cheap ways to maximize the parts I have.. here is a list of what I have already.


LQ4
M6
LS6 Cam, Valve springs, and pushrods
LS6 intake manifold (picking one up next week)
317 heads (debating on having them worked a bit, currently have LS1 heads on the side as well)
SLP Lid, SLP Long tubes, SLP Y-pipe, SLP catback.
picking up 4:10 gears from my shop
LS2 timing chain
LS6 oil pump


If it matters at all, Im looking to do a turbo next summer. (rear mount)
What kind of numbers with a good tune are possible?
What kind of numbers can I realistically pull with some more small mods? What small mods would I need?

Thanks a ton.. coming from a Ford Lightning and Mustang owner.

Off hand id say around 370. You have more cubes than an ls6 and the 317s flow just as well as ls6 243s but then again your comp ratio is gonna kill you.

I would imagine it would be a little bit less than that.

A bolt-on LS2 with 10.9 comp ratio is good for 370-380 through a manual. This LQ4 with it's 9.x comp ratio and 4.10 gears will probably put somewhere around 350 or so.

If I have the heads ported, would I come close to the 400 horse mark? We are talking wheel horse.. Right? I'm looking for 450 crank. Eventually I'm going to turbo or spray it. Have a good deal on a 125 shot and the guy ran stock motor with 125 shot for a season on a stock ls1 and ran 11s

just mill the the 317's and use a thinner gasket, or sell them and get 243/799's... this will get you 380-390ish

consider a GM ASA cam,it works with GM yellow beehive springs.or consider a TSP 228r cam pkg for $600.
