So, i am starting my first ls build and have aquired an lq9 dropout from a denali yukon xl. I am wanting to build something around the 700-800hp range. This will be going in a roller and most likely be a strip car only. Id like any newb advice or help that i can get. Ive stripped it down to the short block and plan to pull the pistons, cam, and crank tomorrow. I was thinking from the little research ive done of stock crank, big roller cam(not sure of numbers), forged rods and pistons, strengthened pushrods with a trunion kit in the rockers fast 102mm intake and tb(or something cheaper with the same flow ls2 or ls6 maybe?). Any help or hints would be much appreciated!

You want 700-800 hp naturally aspirated?

Crysis

You wont make that NA no matter what you do to it

Jmaitland806

No sorry should have stated that it will be a turbo set up

Jmaitland806

no there will be a turbo added sorry

SevensSpeedShop

doable. You already have a good base plan

Jmaitland806

Any idea on budget suggestions?

Crysis

vsr racing stuff is good and u can just use stock manifolds and make your own

Jmaitland806

i was looking at a summit 102mm

Crysis

Yeah they work or you can get like a tbss intake or nnbs intake for cheap those are the best stock manifolds I use it on my turbo build unless you want the looks better

Jmaitland806

which one? I have the stock one that came on it

Crysis

look up like a 2010 Silverado 5.3 intake manifold not the best looking but really good budget manifold you can use like a 92mm tb

I'd call ws6store or TSP and have them give you a bulk deal on everything you need to put it together. Then find a good used huron turbo kit. For fuel I'd go with chrs1313 dual pumps and go with a th400. Then get the appropriate drive shaft and cross member that will work with either a 9" or dana S60 rear.

Jmaitland806

A th400 over a built 4l60 or 80?

Crysis

4l80e imo but depends on individual

A stock LQ9 will hold 700 at the crank reliably, without anything ARP.

I'd probably do a mild cam and valve springs, some fresh lifters, head gaskets.
No need for a big throttle body or intake manifold with boost. Use what you think looks good or is cheap.

Jmaitland806

Im looking for more around 800+ at the wheels

Crysis

You can get arp stuff just to be safe but matts made over 1000 hp with stock bolts you can use ls9 headgaskets works great with boost and arp everything

Jmaitland806

i might just do the head bolts and crank bolt arp maybe the mains not sure yet. Kind of just getting an idea
