Help Needed with 5.3 cam swap
- [QUOTE]Just rebuilt my 5.3 and had to bore out 30 installed replaced the dish pistons with flat top pistons also.
just recently ran the engine for the first time on a run stand and had issues with the idle I found some great info on how tune the engine to what cam you have and got the engine to idle by itself but its way to high falls on its face when I blip the throttle. I somewhat have a idea what I need to do to prevent that but I would like to have some of yall check the data log out and the tune.
CAM SPECS
LIFT: CAM TIMING @50 OPEN CLOSES LOBE CENTER DURATION
