you should replace the push rods no matter what cam you have, stock LS1 push rods flex a lot and can even brake at high RPM.
LS1 blocks are different than LS6 blocks. only about 15% of '01 and 28% '02 camaros got a LS6 block. you can tell by the part number on the back.
1. the LS6 block has vents at the bottom of the cylinders to allow for better back pressure dissipation... the LS1 block did not have this.
2. the LS6 blocks that wound up in the f-bodies were made from the denser casting, and therefore were more prone to tolerate nitrous... the LS1 blocks were almost equally tolerant of nitrous, but were made from a less dense product run.
3. the way to tell if your block is an LS6 block is to look at the casting number at the top, back of the block and on the driver's side... the LS6 casting number is 12561168... anything else is the LS1 casting number.
good reading about the LSx engines.

if your running everything like i am and like we have already talked about then no you do not need to delete VATS in the PCM. i am not deleting it out of mine because i like the fact that i have anti-theft in my 1969 camaro and its that much harder to steal.
read up on LS1Tech.com, there is a cam only section and people put the cam they have and the power they made. a lot of good info there. if you want to keep stock valve springs you need to stay under .570 lift IIRC. |
Yup, I had read before about the LS6 blocks and checked the number at that time, mine is the LS6 block. I've done a fair amount of reading in LS1Tech over the last year but I'm still a little confused. Even though it's an LS6 block, I thought it was still considered an LS1 for a number of other reasons. Are you saying it would have an LS6 cam in it as well or are you saying to stay with the later Z06 cam if I make the change? My motor came from an 02 Camaro. I believe the intake is supposed to be an LS6 as well. The heads are 241's not 243's that Fitz78ta mentioned earlier. The car was built in the second half of 02 so I'm thinking that it must have most of the later upgrades.
Thanks for the tip on the tune. From everything I've been reading the tune is most important that's for sure! When I get the thing finally fired up, I will find a dyno shop somewhere around here that can do the tune like you said. It sounds worth every penny. Meanwhile, I'll keep researching, that's for sure.
As far as the VATS, I agree, same plan. I too like the thought of the antitheft, especially with a ragtop that can be opened easier. I've got the gage 02 cluster mounted and just about have the dash set up completed. I'm pleased with the results. I moved the conv top switch to the old ignition location. The dash cluster area in the 64 will basically be blacked out - tinted glass to see the gages only, the rest dark.
By the way, I did get right steering wheel adaptor set up from Grant to work with the 02 column. I got the correct number through Steve at Madman & Co. Racing, Inc. That was a lead I got from an LS1Tech forum search. Steve was real helpful.
