Rebuilding a 5.7 due to a dropped valve. Currently has a 4bbl but will be doing a vortec head/intake swap. I mentioned in another thread that I was going to run a lt-4 hot cam and it was mentioned this wan;t a good choice due to exhaust reversion.
cam specs are:
Cam Style Hydraulic roller tappet
Basic Operating RPM Range 1,800-5,800
Intake Duration at 050 inch Lift 218
Exhaust Duration at 050 inch Lift 228
Duration at 050 inch Lift 218 int./228 exh.
Advertised Intake Duration 279
Advertised Exhaust Duration 287
Advertised Duration 279 int./287 exh.
Intake Valve Lift with Factory Rocker Arm Ratio 0.492 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio 0.492 in.
Valve Lift with Factory Rocker Arm Ratio 0.492 int./0.492 exh.
Lobe Separation (degrees) 112
SO I am exploring other options how about GM #14097395 which is:
Cam Style Hydraulic roller tappet
Intake Duration at 050 inch Lift 196
Exhaust Duration at 050 inch Lift 206
Duration at 050 inch Lift 196 int./206 exh.
Advertised Intake Duration 288
Advertised Exhaust Duration 308
Advertised Duration 288 int./308 exh.
Intake Valve Lift with Factory Rocker Arm Ratio 0.431 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio 0.451 in.
Valve Lift with Factory Rocker Arm Ratio 0.431 int./0.451 exh.
Lobe Separation (degrees) 109
This seems pretty close to factory specs.
Basically looking for something reliable, being able to use factory Alpha 1 through prop exhaust. and have about 300-325 H.P.
is 14097395 acceptable for this ? any other suggestions?
