so i have a stock 95 gmc yukon gt.it has the 5.7l with the carb fuelinjection system.it is 4wd
mods that follow are:
shotry headers/or longtubes
catless y pipe
custom dual exhaust
intake
computer chip.

 

your gonna have to ask yourself what your really gonna use your truck for.
what kind of sound do you want?
are you willing to run a higher stall converter?
Fuel Mileage?
a lot of guys on here use cams with durations around 220 and lift around .580 and a 112 lsa would give a lot of lope where a 114 will be less agressive sounding.
personally i think i'm going for something for like 224/224 .600/.600 on a 114lsa custom grind.

 

prolly pulling a future stang down to englishtown,nj.just pulling stuff with a trailer.it is a dd also.fuell mileage is just not to get that bad.a rougher idle.more raspy.just something that sounds nast but willl work for me.

 

your in kinda the same situation as me, but i need the torque not to tow, but to move a heavy truck. i would say try to kep it around 220* duration or lower unless you can spend some money on a good converter and if you want that good sound go with a 112lsa i would call comp cams and ask them about the lift to keep plenty or torque. i was originally thinking that .584 was nice but i have talked to a couple of guys who have had custom grinds with high lift lke i mentioned earlier for that express purpose.
also, i downloaded comp cams software which will tell you what cams they have for you off the shelf based on what you wanna use it for. very helpful. its called CamQuest. i think the download is free right now so i would give that a try. you can find it right on the opening page at

wat bout this one.would it work for me.a 2000 stall in the future for me also.

 

That cam seems a little big for a small block chevy in a heavy tow vehicle IMO. I'd be looking for more torque down low to get that rig moving...something with a little less intake duration.

Remember, this is a SBC, so alot of the common cam recommendations that you see around here go out the window...the majority have GENIII engines

 

can u guys find me the right one maybe.just help me out a little.looking for something that will help me towing at the same time give me that noticeablle idle like u guys have in ur 5.3l turcks.

 

Try a comp xtreme 4x4 cam, great tourque made for a truck.

 

ok well since obviously everyone who has said somethin is running a 00+ dont worry about it unless u look up a specific one out of comp cams catalog. Or go to Vinci, they are a sponsor on the far right of this screen. They have I think 4 cams for the OBS 5.7s. Good luck
