I'm building a 5.3 for a s10, all the work is done besides the cooling system and engine mods. I have a built 4l60e and 2500 stall, stock internals with 9000 on the clock. I have a set of stage 1 prc 243 heads, and a set of 1.8 ratio roller rockers. I was originally going to put a z06 cam in it but it wont be completly a daily but will be driven 3-5 days a week still. I will be adding a ls6 intake and long tube headers when they come out in a few more months. and I will be adding spray sometime around christmas. I'm looking to have a streetable engine that can go 12s motor and 11 with spray. keep in mind I'm looking for those numbers with a shortbed st cab s10.

a buddy of mine has a 99 camaro ss that puts down 355 to the rear wheels, I want to kill him with this truck if possible.

the cams that I have in mind so far are the comp 216-220 with 525 531 lift, with my 1.8s the lift is .556 .561 also the same lift with 214/224

also have been hearing alot of good things about tr220's for the 5.3s so i'm looking into them. and have seen up to tr224's in these with good numbers.

if anyone has 5.3 with heads and or more let me know what you have and what power and or times it makes. I'm still learning cam theory and what not I know that the comp i listed and the tr220 are proven 5.3 cams, but I will have more done to my motor then most i've seen with those cams.

thanks
Greg

 

Your gonna need more converter, if you wanna run a cam in that size. A 3600 Yank is my suggestion.

 

Because the S10 is so much lighter than a full size you can run more cam/less converter.

 

TSP 224/581 112 and a 3600 stall, still very streetable and has been a very good combo for many.

 

Is this a daily driver and weekend warrior or 100% street machine?

 

times in sig, with 228 230 cam, full boltons,4.10s,3800 converter.

 

Hey v8 that wouldn't be a Futral cam would it?

 

nope comp cam 228 230 571 573 112

 

Thats damn near the same cam we just put in a buddies truck. It was a futral F11, the same thing just a little more lift. It works very well.

 

For only 5.3L in a street vehicle, I would not go over 230* of duration. If it will see more strip than street, then feel free to go over that.

I would strongly recommend more converter. In my LT1 Impala SS, I still have the stock 191/196 cam in, but my converter is rated at 3200. In reality, it flashes to 3800 though. I drove my car pretty much everyday with that converter for more than 4 years before getting a new daily driver.
