Why did you buy that cam anyway? It amazes me how people just go out and buy the biggest cam possible, LOL. Sounds like lots of this stuff is over your head...which is ok, but its generally a good idea to have a firm understanding of this stuff when deciding to push the limits. My best guess says you will have PtoV clearance issues. You may be able to spin the motor over, but when you heat it up and actually run it, you'll probably make some contact. My advice...get a smaller cam. When you break some valve heads off, you'll be really pissed.
The numbers folks are looking for are things like IVO (Intake Valve Opening), IVC (Closing), EVO (Exhaust Valve Opening), EVC (Closing). Before/After Top Dead / Bottom Dead center. Those numbers. Those are the real cam numbers. Everything else (duration, lobe separation) is a by product of those valve events.

alright... well im going to get the cam (when it comes in) and get every number i can find off of it 
then that way yall can see if ya think it will fit or not (this would be GREATLY appreciated by me!!!)
if nothing else, ill just buy another cam and keep this one till its time to go even bigger in my set up... i really dont care, i mean i dont HAVE to run this cam. its not like im ready to do it tommarow.
now in theory, if i cut the pistons, THEN it would fit??
thanx everyone!!!

It doesn't matter about gross lift(.602/.610) as stated above it all has to do with where the valve is in relation to where the piston is. TDC etc. The timing events that are ground into the T-Rex are designed to work with stock heads. Just because one large cam fits doesn't mean that all big cams slightly smaller will fit. Most cams have 4* of advance built into the cam to give it some low end power. For instance the more advance you have the more power you make on the low end scale, and the more retard you have the more upper power you make( I think). take my cam on a lunati grind here are the full specs 237/242@.50 .595/.595 on a 112lsa. 112 lobe seperation, 108 Int/cl. 10.5* BTC 46.5* ABC/ 57* BBC .05 ATC. Someone with more cam knowledge than I can explain what they all mean. Once you have these numbers you can find out if it wil fit with stock heads.
Edit: I just went to comp cams website and the largest cam they have for an LS1/LS6 motor is the 238/240 .605/.609 112 are you sure the 238/242 cam is the one you got?

Verdad Gallardo I hope you know that the car will idle like total ****. That cam is way too big for a street cam IMO. But you'll see what I'm talking about once you get it running With 4* advance built into the cam, it definitely will NOT fit with stock pistons...no if's, and's, or but's. So you have two choices, notch the pistons or pick a different cam. Good luck.

crap... my bad... dang typo. its a 236/242.
and i know that this cam is big for a street application, but i have had four different cams in my car now and i know what its like to have a big cam in a car. the reason i picked one so big is because for the future build that i plan on doing
when i stroke the motor and get some hellacious heads! but i have been running some numbers and it will be cheaper for me to just buy another cam then to spend the money on damn bolts and gaskets and isky tools to flycut that biatch. so if i do decide that the cam dont fit, then ill just get another cam for CHEAP this time and just run it for 6 months.i know that will 4* built in that the cam prolly wont fit, but what if i was to get an adjustable timing set and retard that bitch 4 degrees back?? would that help it? and can i do this with no ill effects? what do yall think???
thanx!

ok.... i just called comp and they have no idea what the hell is going on.... stayed on hold for 15 minutes and they dont even think that its a comp cam... LOL.... dang, what luck. the cam has not gotten here yet, and when it does im going to get the numbers off of it and then they can tell me all the pertinent info. i swear, this is about to get a little bit more involved then i would like for it to be... lol... the isky tool will cost me about 150$ to rent, along with the 240$ head gasket kit from thunder so that is 390$..... i think ill eat my losses and get a new cam if i do determine that the cam will not fit. its time to get this beast rollin!!!!
thanx for the help!.... any more input would be appreciated!

well... that DOES make me feel better ... LOL... i think i have figured out what im going to do... if it IS determined that the cam will not fit, then i will get the damn hotcam kit for now (425$) and just run through the summer with that, until dec. when i can afford the heads and isky tool to cut this ****, and i will have my BIG cam sitting by, waiting for me > : ) Sell the hotcam for 150$ and put it down on the head gasket/bolts swap. THEN cut the pistons, get the heads, put in the big cam... and life will be good
any more opinions?????
