So I got a 73 Camaro with a "built 5.3", supposed to be turbo but not tuners/fab shops in norcal wanna pick up their phones or answer emails so here I am doing this myself without the turbo cause i miss driving my car
99 5.3 LM7
55lb FiTech injectors
FiTech Intake
102mm throttle body
LS3 MAF
BTR Stage 2 turbo cam-- 226/231 .605"/.598" 113+4
BTR .660 lift springs
450 lph walbro fuel pump
LS7 Lifters
No Afr Guage
Stock pushrods
So Im having an issue with the car not even holding an idle. Sometimes itll take a minute to crank before it starts, but itll start after i start scanning and then crank.
It'll run for about 3-4 secs max and then just die. Im listening to it while it cranks and my guess is that its igniting at the wrong time. Im also adjusting the screw on the throttle body to allow it to open a little, but I dont know if thats helping much. I know VATS is removed so I dont think thats the issue. Other than that I don't really know what direction to go in tuning wise.
Any help is greatly appreciated, can't wait to get this thing on the road and hearing the cam is just too much of a tease.
