ok so i just picked up a re-manufactured lq4 ,and i'm going to be dropping it in my t/a, i've been trying to figure out what would be the best cam choice to go with. its gonna be a stock head motor for now, and i'm looking for advice on cam and intake manifold selection, im wanting to run an edelbrock jr victor or super victor efi manifold and a elbow i'm also looking at doing a fairly decent size cam because i will eventually be changing the heads to a ported ls6 head, i've considered the TR Raptr cam which i think will make good power but im unsure about ptv clearence also considered there split patern any advice helps thanx

CAM SPECS:" RapTR" - 236/242 - .615/.615 - 111 lsa
"Split Pattern" - 230/236 .592/.602 112 LSA

First you need to figure out plans for car. Is it going to be dd? Street strip? Trans, converter, cam selection should be based on plans for car. I have an EPS cam and my biggest thing was not flycutting. I think a custom cam is worth money. lt is worth thde few dollars more to get exactly what you want.

its not my dd its mostly strip but i wanna drive it on the street i also plan to use 150 shot as well

its also a 6spd car and id rather not have to fly cut the pistons

First thing, you need to figure out what punctuation is...

2nd, ditch the idea on the single plane with an elbow. The elbow is horrible for air flow and there are better intakes out there.

Ditch the elbow, keep the single plane.

Based on what he wants / goals, I think an LS6 intake is just fine. I also like his cam choices.

I see you want to run stock heads until down the road. What springs are you planning on using on the stock heads?

Why not fly cut the pistons and run the T-Rex or similar cam? The T-Rex is steetable in a 6-speed with a gear. Will make a ton of power at the track and use your future upgraded heads to the max.

Also, a bit of advice. The veteran members here will share a ton of their LSx wisdom and help you more than you could ever read up on. Most of them will not respond to poorly constructed posts though.

thanks for the advice i post on the form because i know there is alot of wisdom on this site.
I have considered running a t-rex cam but there very hard on valve train, I don't want to fly cut because I would have to remove the heads its a totally sealed engine as it sits at the moment minus an intake manifold, I like the look of the super victor manifolds and from what i've heard/read is they also make very good high end power. However if there is a better route to go than an elbow i would like to know what i should run. I'll also be running a patriot extreme dual spring kit.

I probably would not do the single plane intake manifold. Why not get a FAST? I have the TR 230/336 cam in my LS1. It might be a tad small for a 6.0L motor.

FAST are good but but there also $1000 for intake and TB, whats wrong with the single plane intakes

batboy

For a track car, nothing. They generally love high rpm and make lots of power there at the expense of low end torque. I found my FAST 90 used and already ported for a lot less than new.

did you have to fly cut with your cam

batboy

No, the TR 230/236 cam fit fine with 243 heads milled 0.015". The 6.0L heads have a lot more clearance than that. You might give Thunder Racing a call and see what they think of the fitment of the RapTR cam. With the 317 heads and 4" bore, you probably will be okay.

ok thanks i appreciate it

I'm not exactly an expert but I think everyone has missed your biggest problem, you got a LQ4 which only has 9.4:1 compression, that plus a big cam will make your car very lazy at low speeds. If it's not to late get a LQ9 your compression will still be a little low at 10:1 but with a thinner head gasket you could probably get it closer to 10.2-10.3:1 and get buy pretty good till you change heads.

yea i know im eventually gonna swap to a prc ls6 head i was looking for an lq9 but i got a heck of a deal on this lq4

Fry_

I guess you could put some LQ9 pistons in. I've been looking into doing a 6.0L build for my Monte Carlo and have come to the conclusion that it would be cheaper to buy a LQ4 and put LQ9 pistons in it. You can get stock replacement LQ9 pistons and rings from rockauto for about $325.

batboy

While the LQ9 pistons would be ideal, I think the LQ4 with LS6 heads would be ok unless you really are after every single pony. Can always mill the 243 heads a little, but then you might have PTV issues with that RapTR cam.

shoot if im tearin in to change pistons ill just get the 317s cnc'd and run a dome, maybe ill jus save some more and do that haha, has anybody heard anything about the professional productsy 96mm typhoon intakes
