looking into doing a ls powered fox. i will be using a 5.3 truck motor (lm7 most likely) already have a car lined up just doing some research so when i commit to this i know what to buy. i want the car to be a decently fast car. street manners arent a big concern (want a lopy idle), but i want the car to move when i tell it to. i will probably spray the thing to. what do you guys recommend??

A cam with around 224 duration would be a good streetable cam for the 5.3 but also perform pretty well.

Since you want it to be a litter more on the aggressive side I think is go for a 228/230 .590/.590 112 lsa. In a 5.3 that should do both, sound and perform the way you want

TR224 would work well, the Vengeance VRX2 (224/228), or the cam posted by mark21742 would be a little more aggressive and good choices also.

ok cool those seem like nice cams, what do people rev these 5.3s too i wouldnt mind trying to spin it to 7k

what heads and intake,and exhaust.how much will the car weigh ?consider comp 54-455-11,or get a custom cam.

In a 5.7 the 224s and 228s peak and start to fall off somewhere around or just under 6,500 rpms, in a 5.3 I'd think they would probably peak a hundred to two hundred rpms higher.

I would also get and install a set of aftermarket rod bolts anytime you cam a car and plan on spinning it any higher that stock red line. Do you have to? No, but do you really want to risk your whole motor on stock rod bolts...I'll recomend Katech bolts (cheap insurance)

The rod bolts are my opinion, and just for you info when I install a camshaft in an ls motor I ALWAYS upgrade the rod bolts and will not do a can swap if the person doesn't do rod bolts too..... No, I don't do this just to make more money on a job, and I've never had to turn a cam swap away because the customers understand the importance of cheap insurance.......in my shop for the rod bolt install I charge a 30 pack of Keystone lite, then you have to help me drink it

as far as heads and intake im going to try to find a nice set of 243s and a ls6 intake, this is going to be a budget build. if the car performs nicely im going to put the motor in a nicer car being the one i have is kinda rusty. (i paid 200 for the car) and then i might upgrade some of the stufff
