1 of 3 cam choice
Hydraulic Roller-Good low end torque with exceptional mid-range power for 305 & 350 TPI applications Need upgraded exhaust & aftermarket chip.
XTREME Fuel Injection (XFIâ„¢) Hydraulic Roller Camshafts USING 1.6:1 ROCKERS
RPM range: 1800-5800
valve timing: .006
lobe center angle: 113
intake centerline: 109
valve lash: hyd.
Dur.: 268/267
Dur. at .050: 218/224
valve lift:.57/.565
Lobe lift: .357/.354
comp sells the whole kit wit rockers, springs, rods, timing kit, cam, and lifters, i'm thinking about just going that route... here is the link for it... http://www.compperformancegroupstore...Code=LTCAMSXFI

you aint bull****ing! that duration is pretty big, i wonder why it doesnt say what needs machining on the cylinder heads and i bet that pretains to stock head, i bet any aftermarket head will work
thats actually fast approaching some of the more moderate ls1 cams which are entirely different than lt1. pick something closer to 550 lifts or lower. and someone else can verify this, but i think a good street cam for the lt1 is typically like 211 duration @ .05.
from what ive heard other guys running, that sounds like a strip-only cam

specter is absolutely correct, what are your plans/goals ?
if this is your daily drive id step down the cam big time to maybe a mild or lt4 cam, youre gonna be wasting a lot of gas in that thing.And a huge cam is not always a good thing, you could be losing some power

alih.... are we agreeing? this feels kinda dirty [

to the OP,
I dont have time for the in-depth science-ey explanation. but if you overcam your heads you tend to lose power down low. so the car will feel sluggish off the line and will gain power up top. you will also have to rev higher. this is true of pretty much any cam setup as you increase overlap. the problem with overcamming is that your heads may not support enough flow so you really arent gaining power up top anymore either. so now what you have accomplished is a car that loses torque while not making power either.
my cam is a 232/234 duration 595/598 lift, but im LS1 so my heads can handle these figures. my car builds pwoer like a turbo car. actually.... quite similarly to the way my bike makes power too. nothing... nothing... nothing... OMFG!!!!!!
its kinda like "VTEC OH SH** THATS FAST!" lol
iim worried that you will overcam though with that package. its probably made for cars with ported heads or a 383 setup (i say 383 because the power range seems low for that radical of a cam (relatively) so maybe its a compensation for the lower redline of a stroker)

spec brings up an interesting point that usually is reserved for me to bring up first. if i were you, i'd do heads at the same time i do my cam. that way you can match your heads with your cam and get the absolute best results for what your individual goals are. that's where you need to start....pick what you want out of the car and then you can start putting pieces together. the biggest cam doesn't mean the best cam for you
ah... gotcha! nicely explained and understood... i like the explanations... lol nothing... nothing... nothing... OMFG!!! my favorite... haha i will look into some smaller cam packages... thank you guys for all your help... and even for he questions i asked that didn't even really perain to the sbject (headers etc...) i will let you know what we come up with... i wil call comp and repost the specs of the car etc... hopefully she will be done by thanksgiving wen i get back to my home town... and i willpost a couple vids.. etc... Thanks again guys
