Help with my cam selection....please
Here is my combination:
BBC 454 .040 over (462)
10.2:1 Hypereutectic .250 popup pistons
Stock 781 oval port heads with 1.7 roller rockers
Weiand 8005 Large oval port intake
750 CFM 3310 Series Holley Carb
This is all to push around a 72 Chevelle with a 4 speed and 3.42 gears.
I had a Comp Cams xe268h and was somewhat satisfied with the performance, but the infamous Comp Cams Xtreme energy sewing machine noise really bothered me. I had a lifter go south on me so I'm changing the cam a lifters at this time. I'm thinking about these cams, and would appreciate any input.
Lunati 60203 - 268/276 Dur - .542/.554 lift
Lunati 302A7 - 280/288 Dur - .525/.550 lift
Comp Cams 280H - 280/280 Dur - .520/.520 lift
Which do you think would work best with my combination?
