right now i have a 5.3 with just a isky 212/218 high lift with 112lsa and stock 60e but right now im in the process of getting a parts list together for my lq4 swap. my goals hopefully somewhere near 400 n/a in a 2007 sierra classic cc. here's what i plan on doing.

stock rebuilt lq4, maybe forged rods ( debating on adding turbo/turbo cam down the line)
ls7 lifters
ls2 chain
pac 1218 springs
nnbs intake with xlink, or ls6 intake
1 3/4 or 1 7/8 longtubes
oem oil pump
cam is either
230/232 591/585 112 + 4
222/222 .566/.566 114 LSA
222/226 .597 .598 113
228"/230" .576"/.595" 114

heads will be simple p&P,bowl blend 243s

trans will be a stock 96 4l80e with shift kit, for now i will run stock converter then eventually do a 3400 circle d


if anyone has suggestions on my setup im all ears, this is a daily driven truck so no spray or power adders just yet.. thanks and hope to hear alot also with my setup and guess if i would be near 400

 

Looks like a good list. I would do the nnbs or tbss intake, 1 3/4 headers, and a custom cam if it were me. As far as the rods go it just depends on how much boost your going to want to run in the future. If over 10-12 lbs I would go ahead and do forged.

 

8lbs is max for me
