Have a 1998 L31 in a K1500 pickup - 4L60e with 3.73 gears
buttoning up the motor after a rebuild - 9.1-9.4 compression depending on head gasket and I have the Alex Parts spring kit which will alllow the vortec heads to accept .530 lift
QUESTION: 1) considering a CAM change over the stock L31 191/196 414/428 on 111 LSA to perhaps 1) Delta Cams 203/203 450 450 on 112 LSA or 2) a Comp 08-500-8 206-212 480 / 488 on 112
2) I have the 4 connector black computer which is HPtuner-able -
How tunable is this motor ? I dont want to get into issues of a sub par motor because I have a flip phone ECM in a smart phone ECM world
Any ideas would be appreciated - also would appreciate any tune files for 1998 L31 with smallish RV cams
thanks
