Hi everyone this is my first post. I am planning a rebuild on my old 1975 F-250 Custom. I am going to do a chassis up rebuild to make her look brand new. Going to be using mostly Clifford performance products and I was hoping for your input deciding which cam to use. I am going to use most of the parts from their 6=8 rebuild kit but I am going to use hypereutectic pistons. Zero deck the block then mill .060 off the cylinder head. I am going to use their oversized valves. I'm still deciding on a holley 390 or the 470 truck avenger. Clifford intake and headers. Roller rockers and all the upgraded valvetrain goodies.
I have a borg warner T18 4 speed with granny goose gears. I was going to find a 5 speed to switch to but I decided to keep the good ol T18 and use a gear vendors overdrive. I will be using the truck to pull the boat, to pull my brothers 1992 beast of a mustang to the track, and for all around work (I am getting ready to remodel my parents house and 20 sheets of drywall aren't light), fun tooling around, and tailgating.
Regarding the cam. I'd like to get some more horses out of her but still want some low end grunt. Don't need too much though as I've got the 4.10 rear end and granny low. I don't mind an idle lope but don't want it to sound like she's gonna stall out. I'd think that the clifford 264 hydraulic cam (206 @ .050") 2000-4500 RPM or 272 hydraulic cam (214 @ .050") 2200-5500 RPM would idle well but still give me the performance I want. I'm also thinking about the 270 duration mechanical cam (240 @ .050") 2200-5500 RPM. What do you think about going with a larger 280H or 290H. Do you have any experience or suggestions for cams like these?
