XR274HR-10 in 318

@JoJo

I run that cam in the wife’s 360. I have the compression a hair under 11-1. The rest....750 carb, Weiand Stealth, OOTB Edelbrock heads, TTI “X” piped exhaust, 3.55’s on 26” tires. The trans is a 904 with a custom converter by Pro Torque (since they used to be down the block from me.) Which stalls at 2400.

I feel your compression is a bit low though it need not be high like mine, your converter is way to much and could use a cam with a intake duration as high as 240@050, though that’s pushing it.

If you want to run that cam, (the 274) mill the heads down
(and yes, probably the intake as well, but check fit first!)
Any stock head will have to be fully ported
(since that move will fit your description of what you want from the car and avoid it falling on its face at mid and high rpm.)
and at there cost vs what they will flow afterwards, IMO, your going to be a head of the game if you go with a set of Edelbrock’s heads instead.
