Hiya, I got a fox with a built 351w. Fun Budget build. 30 over with Forged flat top pistons, h beam rods, Weiand stealth intake, msd everything ignition, Holley 650 dp, comp cams xe268h cam... etc. the car will not stop running rich, I can cut the timing down below 10° btdc and it’ll not smoke as bad but I feel like that timing is too low. Car runs good jus smokes a little. 200 miles on motor
