Hey Guys, i got a lm7 5.3 today and been planing my build, as you can see the truck has 220,000 miles on her and planing to push her to 300k but im ready to get my build going, i just have some things jotted down, would love to here ya's opinion and what has been most productive..
so far i got
Lm7 5.3l block
have honed,bored,decked and cleaned up, new cam bearings..
bore out 0.12
pistion bore will be a 390 instead of a 378
stroke will remain stock at 3.622 unless someone says i should do somthing else
Rods out of a ls1
Stock Crank- new bearings
Stocks head with 3 angle valve job port and polished and all that good stuff
Trick Flow TrackMax .575 220/224 0.50 cam
still have to look into springs, lifters and push rods and all that good stuff.
does anyone know where a good build is on her?

im not gonna boost most likely so what should i do about commpression,,
would love to here all opionions EXCEPT for buy a 6.0l. i've determinded to just stick with the 5.3l
