oh ok nice. right now theres a stroker in there with 4200 miles on it..yes 4200...but im getting 4-6 mpg..i want to turn this truck back into a daily driver so i think with the new engine ill get some better mpg and still some pretty good power. here are my plans for the lm7:
ls3 intake
tr 224 or 228 cam
springs? idk...
rockers idk...
3000 stall
long tube headers
performance tune..
goal= 350+ rwhp
