hi everyone
i just finished my new build, is 5.3, l33 aluminum block, stroke to 383 using tsp 383 stroker kit, piston -3cc dome
heads 706, mill to 0.20, valves intake 2.02 exhaust 1.60, port and polish 220cc intake 80cc exhaust.
cam tsp 233 intake 239 exhaust 600 lift 112, lsa injectors #42s
put the engine in the car but when i tried to start it sounded like it off timing?
crank but no start
I'm using my old tune for ls1 bolt on tuning
do i need to change cylinder volume, timing?
I have hp tuners and I'm learning.
any help appreciated. thank you
Car is 1998 Pontiac trans am
