Thread: ZZP vs cam setup...Gains?

the VS you can run on completely stock heads (inclusing valve springs). the XP and s1x you would need valve springs, but would run fine on stock heads (unported) as well. they are just bigger cams and the powerband will be higher up in the RPM range. they will make more overall power depending upon your setup, but it really REALLY depends on the tune and what youre intending on doing with the complementing parts.

Man I just want to have a bad @$$ street car that will outrun these new muscle cars. Its cool to be fast, but at the rate these camaros, challengers and stangs are selling....The old infamous 3.4 setup won't quite do the trick, even with headers. Thus, a small cam and presto... right? Remember I need to retain good gas mileage and longevity of the engine. Isn't the xp cam a little overkill for that?

VS cam is the way to go unless your seriously trying to go deep into 12's. VS cam can get you in the 12's and it has the best street manners and idles great on stock RPM.

The other huge thing to consider is a VS cam won't tear up your valvetrain like a XP cam or any other higher lift cam. You can still run a stock timing chain and stock springs. I'd recommend replacing the timing chain and tensioner when doing the cam since you have to take it off anyways. I'd also replace the stock springs if they have high mileage for some cheap gm L76/L92 Springs which run $2.25 a spring or so.

These are good spring for a vs cam or for rockers up to 1.9 or so

LS Valve Spring. Beehive style spring, 1.800"" install height @ 90# pressure. 1.300"" @ 264# pressure. Used on L76 & L92 engines. Max lift is .570."

Thanks a lot. Will do. I almost went for the comp 105# springs. Is there performance gaims with stronger springs, or are these guys just trying to sell springs? I don't mind paying the little extra if it's worth it in either performance or reliability. Heck, if it's gonna be the same with stock springs and all, I'd obviously wrather go that route. . P.S. you guys on this forum are the SH>>>>>>T

The only performance gain with running stronger springs is that you are able to run higher lift with cams.

Their are many downsides to running stronger springs. From robbing potential power because of a higher load on the engine to creating extra stress on the timing chain and dampener. Comp Cams use to have a great track record with the 105's, but they've had a lot of issues this past 2 years some of their springs are now being manufactured in Mexico.

If your going with a mild setup, get the springs I pointed out along with either rockers or a mild cam like I noted with the VS cam.

Can I run those on stock retainers, or do I need to upgrade?
