Headers glowing and fire flying
Im running an imca stock car with a 383 non stroked chevy. Schoenfeld stepped haeders and the holley 350 carb. im having a problem with the headers glowing and flames coming out of the headers ppl around here are running around 73 for jets. usually that means the engines running lean but i put bigger jets in didnt help. went to leaner jets helped out timing is at 34 adv. any advice appreciated
