Comp XFI 273

I'm thinking of running this cam. What supporting mods are going to get me the most out of this upgrade?

Unless you're planning to run ported big valve heads, a 4000+rpm stall, and rev the **** out of the engine, the 273 is typically too much of a top end cam for the trucks which need a lot more bottom end to get going. The trucks perform well with a Sidewinder, Spartan, Spartan Max, or a Comp 268/260.

You'll never get going fast enough to really get what you want from this cam

Yep you need big supporting mods.

Crazy jay ran a 12.3 with the comp 273 , heads, and 3400 stall and 4.56 but his truck was very very light

Bigger than stock engines also make good use of the larger cams.
