OK guys...I am about to buy a 4.8 chevy and do a 6.0 swap on it, but I am new to Chevy's and need some help. If you had unlimited resources, what would be your perfect 6.0 build...from the motor, headers, possible boost, heads, cam, tune, tranny, stall, rear gears, etc.....I'm planning to use what I learn from this thread to figure out how to do my own build...I appreciate the help guys!!

How would you build it??

 

like i did with a few expections, more SCR 11.5 would be my next move and a fast 90/90 setup and that would be it. o maybe CNC ported 243 castings

 

I'm pretty sure dropping a 4" stroke crank in a 6.0L will get you a 408. I'm not as sure if there is any machining require on the block for clearance? My plan is to build a forged 408 iron block for a turbo, probably 9 - 9.5:1 cr, reverse split cam, stock or maybe ported 6.0L heads.

 

headers go for pacesetter tune if you want go to efi live and do your own tuning, forced induction it would depend on what you want to do get max hp or around 600-700 is good. You got a lot of things you can do oh and tranny to go with a good one like a 4l80e and save the headaches for later.

 

So if I choose to follow your basis, I would need to get the LQ4 right?? I was originally planning to build it N/A, but now I am starting to think about going turbo instead. I have always wanted to run boost, but could never afford it. Now that I have the chance, I want to make sure I do this right.

 

Sounds like you are ready to get down to business.....

 

The cheapest way to build the motor would be an lq4 iron block. The forged internals are up to you, I think they are a good idea around 550-600 hp. If that is all that you want to make, new rod bolts should be the only upgrade in the lower end. If you wanted to save some money, you could forget the 408 idea and use the 6.0L with its stock parts. A cam swap to something turbo-friendly would be a good idea (like a 230/218 on a 114 or 115 lsa). If you search through some threads you can get ideas of what is possible with each set-up. The stuff I know is limited as I just started researching turbos and have never had a truck with one before. I like the front mount turbos that members here have put together, they make tons of power too.

 

I dont know..I like the whole 408 idea you mentioned before. You guys are making me more and more excited about this build every day...haha

 

Small update, I think the 4" crank with a 4" bore would make a 402 not a 408. Not much difference but I think you need to bore the 6.0L .030 over to get the 408. I don't think there would be a reason to bore the 6.0L unless it needed to be cleaned up. Matt, what kind of power do you want to make?
