Latly my 351 C has been running a bit shitty. But it's been getting worse, and worse. I tinkered with the carb and that helped some for a little while, but went back to the shitty stage. I replaced dist cap, roter, and plugs. No change. I checked out the fuel filter and it looked clean. Fuel pressure is 7 lbs. Here's the build; 351C bored .030 4V heads, closed chambers, stud mounted roller rockers Mallory Unilite dist. (electricronic) vac adv. MSD 6A MSD 8mm wires Holly 750 vac. Weiand Excelerator intake solid cam 226/300 dur @50* 540/560 lift Mallory fuel pump, regulator, and filter I also put port plates on the intake and exhaust for torque. Now I thought it was running to rich, that's why I adjusted the carb. At idle it barely runs, but when giving the gas it gets running, but not that great. My thought is carb or distributer. I'm going to limp over to JBA and have them tweek it out and dyno tune it. Any thoughts on what might be going on? or what I might try before taking it to the pro's?
