Which FE Cam & Lifter manufacturer is best?

[A98Coupe]

Brent,
Thanks very much for the advice. I had no idea Bullet had so many grinds to choose from. I will be discussing my build with my engine builder, but just wanted some additional opinions.

Rick L.,
Wow, so many questions, but good to see you active on CC again! Anyway here goes with some answers about my application:
- This motor is replacing my iron 427 SO in my Kirkham 427
- Rear end ratio is 3.07 with 4 speed close ratio toploader gearbox
- Looking for around 600hp for mainly road use but some track day & hillclimb competition use. RPM probably no more than 6K
- I like the idea of big bore shorter stroke for fast, free revving feel, so am leaning towards 468, but I know 482 will give me huge amount of mid-range torque where I need it.
- Compression target 11:1 on 99RON pump unleaded.
- Heads would be Edelbrock Stage X, fully CNC port & chamber work by Barry R. I like the BT heads, but the raised exh. ports won't work with my Kirkham headers.
- Carbs would be Holley 2x4, 600 or 750 CFM race prepared by Barry R
- Inlet manifold is a BT dual plane to make the package more driveable at the expense of high end hp
- Exhaust system is Kirkham's own side pipes which flow much better than original 427 systems
- Not sure about roller cam type yet - many conflicting stories about solid rollers

I will be speaking to my engine builder very soon to start pinning down some component specs.

Thanks again for advice
Stuart
