dissasembled the Lq4 this week, crosshatch on the walls, pistons are good, bottom end is good as well. No scary messes in the oil pan either! not bad for an 89,xxx motor
i picked up some assembled 243 casting heads for 300 dollars from my transmission builder, all they are missing is the little coolant plug for the passenger side head and valve covers.

I still have no picked out a cam and it's been bothering me to hell as to what i'm gonna do about it.
i do know if i bolt on the 243 heads as is on to the lq4 i'll have 10.2:1 compression.. which is only 1 point up from the stock ls1 compression right?

What would you guys do from here? the current mods on the car are...
ls6 intake and 36# injectors/ported TB/ MTI LID/ PACESETTERS.

planning on a 3200-3600 stall..

I want 400rwhp but with a nice torque curve.. i notice some people don't even start making good power until late in the powerband..

also, will the 6.0 drop the front end of the car a bit? because the car is stock height and it needs to come down LOL.

Would a Vrx5 Cam be optimal for a daily driver?

I have a lq4 with 799 heads and its gonna be running a 216/224 cam with a 2800 converter in a hunting truck... I had a 230/238 eps cam and made 407 on a unlocked converter on my ls2.. Id look into the vrx5 or a 234/242 xer cam but to make 400 through an unlocked auto your gonna have to go big on the cam... The cam I have in my ls2 now is 239/246 and it drives like the 230/238 cam..

a torquer v2 is a nice street cam i put down 414whp in old setup with it
or a 228r from TSP works great too dont know specs of the vrx5 havnt run into anyone running it?

well guys i really wanna be able to dip into the high 11's on this setup, but i don't want it being a dog around town, i had a 5.3 in a 97c1500 truck that had around 9.6:1 with 243's and a tr220 cam and it was a DOG..

would i be fine with higher than stock ls1 compression? maybe like 10.5:1?
would i run into any PTV clearance issues?

did you mill the heads on the ls2? what compression does the ls2 have? i'm starting to think if i match the ls2 compression i should see similar results to yours

Mill the 243's to 62cc... A big cam will LOVE the compression and itll make more power

Call me tomorrow at Tick if you would like to discuss a camshaft whether it be off the shelf or a custom deal. I can spec both for you!

Just a FYI I now spec all of our custom cams for our customers. Lobes used, duration, lift, lsa and icl advance are all chosen in house and not by a third party!

So you at least know that the guy you're talking to actually knows how and why the package works and why it will work best!

i tell everybody to ms3 there car but i was tryin to be considerate but if you want a beast then ms3 it :-)

I had ported 317 heads and they were milled to 65cc and it was 11.0 compression

greenvortec97

iTrader: (1)

how is this possible if the 243 heads are 64cc?

stock 243's on a lq4 yield 10.2:1..?

edit: nvm, the ls2 must have flat tops

Just surface the heads a little and put in a cam in the low 230's duration and you should hit over 400whp easily. My motor is just a little bigger but with 241's, 11:1 compression, and a 235/235 cam, I was making 400whp by 5000RPM.

would a .010 mill bump up the compression and still allow me to run a cam that size?

KCS

iTrader: (20)

Yes it should be fine.

it appears my last posts didn't make it through.

i settled for 10.5:1 compression.. (how much will i have to mill off of the 243's?)
and i chose the tsp torquer v2 cam (will this cam cause any issues?)

youll be fine with a torquer 2 its a good street cam not too aggressive

Seen a 99 ls1 vette with unported 243's, torquer v2, ls6 intake make 414 to the wheels with a 6 speed. I think you'd be close with a cam in the 230s through an auto.
Edit: it was a good friend's car so Im sure of all the mods.

not unheard of at all i did 414rwhp with 241's torquer v2,bbk ssi,90mm tb,pace Lt's,slp loudmouths,tsp y pipe, in my 6speed ws6

Alright guys, im really trying to decide between the El Toro Custom grind and the TSP torquer v2.. Predator Z showed me a graph of the el toro cam on a stock compression lq9 which is (10.1:1) and the torque curve was amazing

does anyone have a dyno graph for a relatively stock 6 liter motor running a torquer v2 cam?

Don't chase the almighty dyno sheet.. Get a cam that'll suit what you intend to do w/ the car.. The Torquer is a very nice cam. make's great power.. and has a aggresive lope to it.. But you can always call Tick perf., or any of the other cam gurus' and see what they come up with....
