I have a mildly built LS1 in my 99 formy...i want to upgrade the valvetrain so i can spiin her to about 7500 RPMs...what kind of valvetrain is available for this build?
the car will be h/c car with forged bottom end..and maby some spray as well..i have seen the scorpion rockers/ fuel rails etc..and they look nice..but are there any particular gains? hp/tq? reliability issues? warranty? i am curious as to who has what on their cars and or any problems that they have encountered with aftermarket parts.. thanks in advance

 

Are you gonna run a solid roller cam? If you are thinking of going that high of an RPM you are in that arena. I would consider it because the 98% majority (That I know of) hydraulic roller cams fall off at 7200 for the latest. Either that or stick with 7200ish.

Maybe the stock upgrade from Nasty Performance would be the way to roll. It is cheap and is a strong/reliable rebuild.

 

going to go with a vindicator and ls6 heads and i already have the ported oil pump , comp lifters, comp pushrods, crane springs, going into a forged bottom end..just want to be able to reliably spin it to 7K
and do you have a link? what about the scorpion line? anybody?

 

What kind of intake are you going to put on it???

 

well right now it has a stock LS6 intake and tb but soon to get a vengeance ported TB when i get back...cant afford the 90/90 just yet..

 

Why rev to 7500? A efficient cam and valve train for that application will be a pooch on the street.

 

You will be making poo for power at that rpms. You may can get a useful 7K out of it, but that is pushing it, big time

 

she redlines at 6500 rpms right now...and my goal is 500 rwhp All motor...then comes the 150-225 shot...just want to make sure the rest of my engine is as bulletproof as the bottom half...

 

All you have to know is one phrase: How fa$t do you want to $pend?

 

crane quick lift rockers is what i would put on it, lifters wouldn't hurt either. 7000k+ capable, but motor will fall off on power way before then. dual springs will be a must, along with lightweight valvetrain components to help reduce harmonics or float issues.

 

One word:

JESEL

 

anybody got a link or part number so i can do more research on this? and 7K would seem safe and from what i understand is a bit retarded to go beyond that with the build i have in mind...and thanks again for the help
