So...
I have a pretty freaking radical cam in my 72 c-10...
355, XE274 cam, Trickflow 23° 62cc heads, Performer RPM intake, 750 cfm carb, and Hooker comp headers... stock torque converter...
So... here it is.
Of course my truck runs like crap from idle to about 1200 rpm... but if I pull the choke (not enough to mess with the rpms, but just a smidgen) it runs fine (no bogging down) up to 1200, at which point I open the choke back up again, and away I go...
So... It's like it needs to be richer at off idle to 1200 rpm... is that the metering rods that would change that?
