I've tuned a 7500rpm car.......he just doesn't have one. He will need cams to make power up that high, and then he will also need new valve springs, porting, and new lighter valves. If he had that we could be talking a different story, but I was trying to think with my head.

I think he thinks because some other people set their rev limiter to 7400-7500 to account for the timing pull that he can rev that high. I told him we can just add timing to compensate for the loss, but I don't know why that didn't make sense to him.

Even if he said he would never shift above 7200 I still wouldn't tune it that way, because with the tach delay and powershifting he would be up around 7800+ rpms. That's risking instant failure.

NOW he does, but before he blew the motor TWICE!

Alright. You guys win. I bow down to your information. I'll just put the money towards a ported head instead.

Cam.. Who's doing your cam regrinds? I wonder if we would benefit from just a hotter exhaust cam.

Crane cams is doin my ****.

Steve what are you talking about when you say it pulls timing? When does it pull timing? I had my limiter set to 7200 and I would shift 7000-7100 and my car would never pull any timing.

Only option for LSJ is cam regrinds. Blanks do not exist, I thought everyone knew about this.

AFAIK, you can techincally use 2.2 cams, but you won't be able to use our cam position sensor. All that sensor is used for is getting the motor started on first crank. I run my car without the sensor, it just takes about 5-10 crank to start, depending where you turned the car off at.

Pretty much everyone modded LSJ around here runs a 7400 limiter and takes it there everytime. So far no one has nuked their motor, and it has been over a year. LSJ starts to float at 7400ish.

I know where you can get a ported head with the reground cam, and upgraded valves and springs.

Could i just get the head steve? I'm going to stay with the 7000rpm limit. How much?

i'm pretty sure that is' been proven that they float at 7200...

Is that true!?!? I thought it was used for like ignition or something. I should disable my cam sensor so my car has to crank over a few times, before it starts. I always notice super bad ass cars take a bit to start up

What I meant was from GM basically. Not everyone has infinite money to toss around into an econ box.

JBP gives you the option. send in your cams for pay for a blank.

Man you guys are nuts. striving for more more you abuse the motor when you could go faster just by taking advantage of our torque down low. when I run a 1/4 I dont shift passed 6200 rpm's. I would run out 3rd gear though. now with more bolt ons I wll use fourth.

I used to run every gear to almost 7gs but found not as much success shifting earlier. Used dyno sheets and annalyzed difference in engine rpm between gears to come up with a plan and shift points. worked for me. 13.9 with stage 2. only other faster GMS2 I have seen is 13.8

If GM sells them then why don't they offer them to the public. Also, it has been proven to not trust JBP, lol.

Where does it state on their site that you can send them yours and get blanks in return? You sure you just don't mean the core charge when you buy their "Tri-Flows"? I could be totally looking past it on their website.

With my 3" Exhaust and Lightweight Flywheel, my car has no low end anymore. I have netrual balance shafts and cams waiting for the car though. Just need head work and valve springs. Plus I will be going Turbo myself once the motor is finished.

Best I could get out of mine at the track was [email protected] That was with shifting @ 7100ish and before the engine works, clutch, and mounts. I need to get back on the dyno and see what the power looks like.

What the hell are you talking about!?!? Read a couple pages back. I BOUGHT THE BLANKS! They are for the L61, the exhaust cam is shorter and doesn't accomidate the cam sensor in the LSJ head.

I am not calling you guys wrong. I am just saying in our search, we came up blank. GMMP even told us they won't give out any information for LSJ blanks, or anything about their Comp grind in the build book.

If you know how to go about getting LSJ cam blanks for GM, please let us know. If JBP is the only magical way... well then I personally won't trust them, but that is just me.

^^^ Exactly my point, JBP is out of the question. I don't see how they are the only ones that can produce these blanks.

Tag was suposed to, but I guess they gave up and handed it over to Mase who used to work for them. The confusing part is what happened to the money that people gave Tag as a deposite. I'm not even sure Tag was heading in the right direction with thier design.

Your car wont pull any timing unless it is the GM tunes. Running like 20+ degrees of timing on pump gas is redick. Oh I know. Also Just because your timing is advanced doesnt mean you are making any power only early detonation, right Cam haha.
