I'd like to have the P/N for the 425 lift cam for the future .Is it for a reverse rotation engine?I have 2 more 4 bolt (010) blocks , a gear drive timing set, 041 p/n 300hp stock corvette heads.Just waiting to have some money thrown at them.BOAT = break-out-another-thousand. (Don't tell my wife!) I think the 350 weights bit less vs 305 (alum. intake) |

I'm turning 5400 RPM on the tach and Perfect Pa$$ at about 52.1 MPH verified on Perfect Pa$$. GT40 Heads cleaned up a little, Weiand Intake, Carb with secondary metering blocks, DUI ignition, and my favorite weapon of choice...Hi-Tek headers.
 Stock cam at the present time but saving up for a new one from Cam Research.
Thanks! |

I was bit off with my memory. The stock 350 comes with around .400 lift. Going with .410 will give you about a 10-15HP increase according to the book I have. That shows a .430-.440 lift for a moderate increase in HP. then a .440-.450 lift for a a 383 or 406 engine. Keep in mind these are 1.5:1 rockers. The .410 lift uses a Comp Cams XE 250 Xtreme energy cam. The .430 lift cam is Comp Cams XE 256 Xtreme Energy and the .440 lift is a Comp Cams XE 262 Xtreme Energy. I'm sure that all of these can be had in a reverse rotaion. Hope it helps. |

The .410 lift cam plus 1.6 roller rockers ends up at.437 total valve lift.I picked these parts for performance and longevity. |

I've had my '96 SN going 70MPH before. Full tank of gas, loaded with gear.
Of course, it was on the trailer at the time.
