72_Cutlass_LS_Swap

I have a 72 Cutlass that I'm doing an LS Swap on. I have a 02 Silverado LQ4 with LS3 Heads/Intake, with Nick Williams throttlebody. Looking to put a Cam in it before completing the swap but I need some help. I've been looking at these 2 cams but not sure which one would be best for me. It's my project car that I would like to drive maybe once or twice a week at most. Let me know if I need to provide anymore info.

Do the Pat G. It'll be easier to street drive

What rear gear and tranny?

Hmm, how big is your stall? If it's a fairly large stall I'd get the first cam, if not... Get a shorter rear gear (maybe 4.11?) and go with first cam as well.

I haven't decided on Stall yet, just now putting my setup together, but a friend of mine told that the CompCam might be too be causing it to not be very fun to drive on the street. Unfortunately I don't know much about Cams so I tend to want to pick the Cam that sounds the choppiest

Your friend is right, that is a fairly large cam. That's why I asked about your tranny/stall/rear gear. With a good tune, a shorter rear gear, and a bigger converter you should be fine. If not, it might bog a bit and make it kind of annoying to drive. If you want a nice choppy cam for your setup... lean towards a 24x/25x .60x/.61x 110-112 LSA. That'll give a nice choppy idle. That's pushing the limits on a 5.7, but on a 6.0 I think you'll be fine. I know what you mean about wanting choppy idle, my cam selection will also be decided by that, even if it means giving up some performance

any off the shelf cams that you'd suggest?

Hmm, I have an LS1 so all my research regarding off the shelf cams has been for a 346 LS1. I know that the T-Rex cam is one of the biggest off the shelf cams for a stock cube LS1, so that'll be somewhat mild in an LQ4. Check it out on YouTube and see if you like the sound. Personally, I think the T-Rex on 112 LSA sounds badass in an LS1. I bet it'd sound nice in an LQ4 as well. The T-Rex specs are: 242/248 @.050, .610/.615. Pretty big for an LS1. Look for something similar, I suggest giving TSP a call and telling them about your application and what you're looking to do. They'll be a big help!

I ended up going with the Pat G cam, hopefully it'll work out for me as there's no turning back now

going to pickup my new springs and pushrods locally so hopefully I'll get the cam by the end of the week

Cool man good luck I think you'll be happy with the choice. If you want it to be choppy you can bring the idle down a bit. I used to have a similar cam in my LT1 set up and I had it idle a little lower and it really brought the mean sound.
