Nitrous made me do it
I seem to have melted my piston rings. I decided while the motors out to replace it with an ls3 stroker and go n/a for a while. Gonna be down for a while but I will be ready for Racewars!

That sucks but I feel compelled.
What are the full specs on the new LS3?

It's a terrible feeling for sure but sounds like you are on to bigger and better things. Are you planning on spraying or boosting the LS3 eventually or keeping it NA?

Motor is being built for n/a specifically with intentions on bracket racing. Should make around 575hp, hoping for a solid 10sec reliable/ consistent machine.

Only 100 wet, have an arming/timing retard/widow switch. the guess is there was a fuel problem.

Most of the time, there is a timing issue and not a fuel issue... but I may be wrong.
Your car was cam only, right?

Cam and stock ported heads. Your probably rite about the timing. Really didn't look into the problem that deep. I made up my mind on the new motor pretty quick.

How many passes did you make on that 100 shot. You have me 2nd guessing myself now. I have kit hooked up just waiting to hit the button. Did you spray it on a dyno the 1st time?

it was sprayed on the dyno. I wouldn't really second guess yourself. If everything is rite you'll be fine.

I was gonna have TTP put in a nitrous tune for me so I'm sure they will adjust everything as needed. Thanks for the heads up tho. Good luck with your Ls3 build. There's an LSA for sale on CL for $9500

Not bad for a small setup.
Timing brakes parts. If you went lean, normally it doesn't make power... its not nearly as bad as too much timing.

You can have TTP do the tune or get a LNC001/timing twister and pull the timing when you want and run NA other times.
If you want, a sunday or a day when you can, do some runs and pop the plugs out to make sure everything is okay.
