well i ended up picking up a 4.8l a month ago with 30k on it and before tossing it in my truck i was looking to build it while its out. I'm wanting to do mainly the top end and a custom tune afterward. Any advice on what setup I should do, cam, heads, valves, etcs... Im not really wanting to turbo it either. so any help would be nice.
well its a standard cab long bed 2000 sierra 1500 4.8l 5spd 4x4 lifted 6" on 36's. I have k&n cold air, BBK headers, High flow cats, Flowmaster 3", and a bully dog programmer. I did all those bolt ons to get more power which it helped alot. i blew out the 10bolt so i swapped in a 9.5" 14bolt SF w/ factory locker. my budget is around $1500 i want to put into the motor build and looking to get the highest HP for the buck, Id be really satisfied if I could get into the 400's.
You won't be able to get New heads, cam, and a dyno Tune on for that price.
Heads alone start at $899

You can purchase used heads and new cam for well under $1500 and still have $ for tune. I agree with selling the 4.8 outright for a higher mile 6.0 tho. You'll be better off and be able to meet your 400hp goal

Don't get me wrong 4.8 is a great little motor, there indestructible and you can make some serious power out of them but that usually comes in the form of FI. I've got a N/A mildly built 4.8 in my truck and its pretty stout for what it is. What's your plan?
