LS1 Cam

what gains could be seen with one??

The actual stock LS1 cam? Slim to none and not worth the time and $$$$$$$$$$$$$$

1998 - 2000 Fbody
202/210 int/exh @ 0.05" duration
0.496" / 0.496" int/exh lift
116 LSA

Vs

5.3 LM7
190/191 int/exh @ 0.05" duration
0.466" / 0.457" int/exh lift
114 LSA

For a good noticible gain go with something with a duration in the 220s with whatever flavor of LSA you like. A TR 224 is a good proven "off the shelf cam"

thought you meant the ls6 cam dude!!

I have the 1998 cam in my truck. It runs good but I want more lope. I goning to order a custom one soon and you can have mine. I'm up south of you.

hmmm, alright. thanks for the info guys.

i put a camaro cam in my 4.8l and i could tell a slight difference. but not much.

I did cam & heads at the same time and saw approx. 25hp, but after tuning in approx. 50hp gain.

I just installed the 2000 Vette cam in my ’01 5.3 with mildly ported 706 casting heads, yellow springs, and LS1 intake for my LM7 powered BMW project. Noticeable gain or not? Probably not noticeable seat of the pants vs the stock truck cam, but it should help bolster mid range and top end a smidge. My guess is if the price is right, at least go with the 2000 Vette cam, or the ’01 LS6 cam, (nothing smaller) other wise aftermarket I really the way to go! More aggressive ramps, for more lift under the curve.

Here are some OE LSx cam specs for those interested.

2000 Y body, Vette,

LS2, Vette and GTO. (Does not have the cam sensor reluctor ring on the back of the cam that the GEN-III engine use. Requires the LS2 front cover and cam gear. Not sure the PCM will read the LS2 cam gear either, sorry)

Eh....I chased a 2000-only auto Vette cam for three weeks on eBay but the homo listing it would never respond and never post the numbers on it. I think they know some people look for them and try to sell other take outs as that one year specific grind.
