LS6 cam in LS1 question

If I put LS6 cam/lifters/springs in a 2000 LS1 engine, do I need to re-tune? This is for my off-road sandrail with a Street & Perofrmance moded ECU. I know it will probably help, but will my ECU compensate enough to not need the re-tune?

Can I still use the stock LS1 pushrods?

What if I went to a LS6 intake? Re-tune????

You would definitely want to tune it. You could use the stock pushrods, but you may as well upgrade to some hardened ones, your stock lifters would be fine.

I ran a 02 LS6 cam in my car for 2 years on the stock tune and it ran perfect with no problems. If the ECU is tuned for a stock LS1 cam, it will work fine with the LS6 cam. Tuning will help (especially bumping the shift points and rev limiter up). Stock pushrods and lifters are fine. I would search for a used cam/springs to save $$$. I got mine used for $150.

Thanks for the replys. I already have my rev limit set to 6200. Seems too soon to find used cam/spriongs.

actually you need a 7.425 length pushrods for the ls6 if you have stock heads to take full advantage of it. I have my rev limiter set at 6600, and as far as a tune, after logging on hptuners, there wasn't much that needed to be messed with, you should be fine
