I'm just wondering if it's possible to rev my motor higher because it's fully built. It's a DOHC ZC, it's been sleeved, has SRP pistons and eagle rods. The whole assembly will be balanced. I belive the rev limit is 7200 or 7400 on a stock ZC. Also throw into the mix i have a Zdyne comp and it will be tuned before i over rev it, that's if it's safe. I'm hoping to rev to about 8,000-8200. I'd really like some opinions. Thanks

 

did you upgrade the valvetrain?????? if not, dont rev past stock rev limit.

 

upgrade the valvetrain (springs, retainers, valves, guides) and you could probably hit 9k with that thing.

 

Well if there was valvetrain available for the ZC i would upgrade it, but there is none so i'm kinda screwed. I could send my stuff to ferrea and have them custom make it, but that's WAY to much $$$$$. I wish someone would wake up and start makin performance parts for ZC's

 

I wish that were true too. One time I had wished there was an inexspensive way to modify my engine and it worked with my intake.

 

AH HA! Finally found a shop the has some experienc with ZC heads. Appearently they mod the head to fit LS valvetrain and there's aftermarket LS valetrain available. WOOPIE!! So i should be able to safely take it up to 8500-8800.....hopefully.
