I am wanted to get this cam for my mostly stock car and want to know if the pushrods should be stock length 7.4 or if i need something longer??Also let me know what springs you guys are running with this cam.Ls6 springs just dont sit well with me but lpe says they work good.give me your input.thanks

I used my stock pushrods and bought the Manley 1423 spring kit from SDPC2000.com for $179 which icluded Ti retainers. All worked well for me.

I used the stock length pushrods. I really enjoyed the power the cam made.

speedfreak what kind of springs did you use with yours.i am considering the manleys but i might lean towards a beehive spring.

also let me know sleeper if those springs you have are noisy campared to the stock springs.thanks guys

you'll get noise with any aftermarket spring because the pressures are higher.

it's not real loud, not as bad as you think.

decided to go with comp 918's just because they are a very good spring from what i read and the guys at lpe said they would also work if i didnt want to use the ls6 springs,just costs more.does anyone know if the titanium retainers they recommend will give me an installed height of 1.8.thanks guys

I went with 918's and chrome molly 7.425 pushrods. Unless you have the LS6's longer valve stems, you need to increase the PR lenght to keep the lifter preload at the proper value, compensating for the smaller base circle of the LPE cam.

Anybody got a before and after of this cam? I have been searching for some time, interested in lower RPM increases as well as peak values.

after with LTs and ORY

let me know what length pushrods you guys are using .I called lpe to find out what the base circle on the cam is so i could figure it out myself but they dont know that measurment.My motor is stock and i dont think the 7.4's would be correct with that lift on the cam.

See my previous post. 7.450 might be o.k., but to play it safe, 7.425. And I intend to dyno my car after the cam swap, but it will be a few weeks yet. The only change will be LPE cam and an underdrive pulley.

I'm running my stock pushrods and the springs that come with the kit which I believe are "484" LS2 springs.

Hasn't been a problem in almost a year. Nice and quiet

Dyno numbers in sig.

yeah i will use the 7.425 length just because i know 7.4's wont give me the stock preload.I know there is no way the base circle on the gt2-3 is the same as stock so i will definitly use the longer ones to make up for it thanks guys.

Why? LPE says stock length is fine. If mine was too short, I think I'd hear that. Mine is as quiet as stock.

I know what lpe says it probably puts you in the .030-.035 preload range which is still ok but i want the factory preload settings of .050-.060.I rather keep the factory preload than what lpe says will work.
