Just a looser converter 2800-3000 and a 650cfm possibly 700cfm carb will make it come alive...
But one other question where is the 11.3 to 1 compression coming from...? What pistons...? Those 882 heads with the large valves work good together but they are large chamber (76cc)...
BTW if that is a Summit cam with those spec`s its the 1107 part number and with a stock converter it must be hell...?
