new to the site, been lurkin for awhile, I'm starting a LY6 6.0L build with L92 heads, gonna be a stock bottom end motor, cammed and carb'd for a 92 S-10.have been looking at some different cams and not really sure just yet, sent comp cams a request and they recommended their 277LRhr13 grind, 277/285 duration, 227/235 @50 and 614/621 gross with a 109 center line. does that seem like too much for a stock bottom end motor? It does have the factoy pistons with valve reliefs, but wasn't sure if this was gonna be pushin things.

 

can't say for sure on that particular cam, but I have one just slightly under those specs (223/231-.610/.617-112) and PTV clearance on my LY6 is fine.

BTW.....still have the complete LY6 intake with throttle body?
