Hey guys, I have an 83 K2500 suburban. Stock LT9 350/Sm465/3.73s.
I asked comp cams what RV type cam they recommend for my engine. They suggested this:
Grind Number:XE256H
Engine Family:Chevrolet 262-400 c.i. 8 Cylinder (1958-1998)
RPM Operating Range:1,000-5,200
Cam Type:Hydraulic Flat Tappet
Lifter Style:Hydraulic Flat Tappet
Camshaft Series:Xtreme Energy
Camshaft Gear Attachment:3-Bolt
Usage:Street/Performance
Valve Springs Required:Yes
Camshaft Material:Cast Iron
California Proposition 65:WARNING: Cancer and Reproductive Harm P65Warnings.ca.gov
Advertised Intake Duration:256
Advertised Exhaust Duration:268
Intake Duration at .050 Inch Lift:212
Exhaust Duration at .050 Inch Lift:218
Intake Valve Lift:0.447
Exhaust Valve Lift:0.454
Lobe Separation:110
Assembly Lubricant Included:Yes
Intake Centerline:106
Lobe Lift Intake:0.299
Lobe Lift Exhaust:0.304
My question is, what kind of gains can I expect from this? I'm trying to get more towing power on the cheap.
