LM7 383 Build Up

[blackout]

Dang Ty--you have learned a lot so far. For the most part, every one on here has given good advice.

The TBSS intake with 90mm TB will be a welcome addition, but not needed. A truck intake with a Shaner PnP TB would have been fine.

The LS6 cam will leave you saying, "I wish I had a bigger cam." AND NO RE-GRINDS! Re-grinding a cam removes the heat-treat on the lobes and makes them soft and more prone to failure. A good cam for your build would be a 218/224 .563/.563 113+3 LSA.

Good luck with it all.

Yeah man I hear you on the no-regrind thing. After talking with some people I found out that re-grinding a cam is not the way to go.

Where would I find some more info on that cam? The thing I am worried about is tuning it and having it be a reliable runner time after time. That is why I choose the GM LS6 cam because they have a good reputation for being a good quality cam.

I will be using the truck as my daily driver, but I do want respectable hp and tq out of it because it is my towrig for my snowmobiles.

I think you're still going to want a bigger cam than that. I may sound like I'm preaching here, but you're putting all this money into machine work, intake swap, blah blah, and then skimping and going with a baby cam. You can EASILY daily a 220/220 or 224/224. Don't get me wrong, it's your build, but like Tyler said... a cam like that will make you say... MAN, I wish I had more. My suggestion to you would be the TSP 220 or something similar. It's small enough to retain low end and drivability with a small (2500-2800) stall, but big enough to give you very noticeable gains.

i would call comp or texas speed ( talk to matt ) or thunder ask them about a cam for your setup, anyone of these companies will give you an idea of which cam would be perfect for your build, just give them all the info you can and let them know what you want out of the truck and youre good to go

flip that intake over and take a pic of it, is it the cathederal port or rectangular port? i know they make both, just wanting to know which one you got. the rectangular port wont work with the 243 heads.

just tuned in and i'm curious...

for a 5.3 -> 383, what bore & stroke are you using?

You would need to bore the block .125 to get to a 3.905 bore (same as a LS1) then use a 4.000 stroke if I'm not mistaken.
