Posted by 55clippercustom On 2009/2/6 11:43:07

Hello,Im finishing up building my 352 up and getting ready to install in car,and hopefully have running over the weekend!! My question is what should I gap spark plugs at??I had thought about 40 thousandths to compensate for unleaded fuel?? I have this car and engine on a project blog on here.This motor was rebuilt back in 1981 by someone other than me,and Im assuming there prob. was nothing special done during that rebuild to compensate for unleaded fuel(I really don't know) So I am assuming nothing was done. Also what other recomendations or simple adjustments do you have so that I can safely run engine on today's(Unleaded) fuel??Should I use a lead supplement? Thanks for all your input in advance!!!
