Built a Chevy 250 inline six for a customer for his '72 C10.
Can't remember the exact specs of the cam we put in it, but it had a decent lift with a pretty quick drop on a 112? 113? centerline. Bored .030, hardened seats, polish and port on the head. Offy triple single barrel intake. Pretty mild just tooling around in the inboard carb, but became a fire breather under full throttle with the outboards open.
Owner wanted a truck he could use to haul his 390 powered T-bird around with (we restored that, too). Convinced him not to go with a generic 350. He wanted low end torque, he got it with that little six.
