Seeking 318 rebuild advice
Normally ,I go Magnum, use what you have .Here a basic 318 gig: Like the headers, a stock cast iron /Edelbrock's Performer 318/360 dual plane/ your choice of carb/a Summit cam & lifter kit( K6900 real mild/K6901 a mild copy of the original 340 grind both ground by Crane/ a good valve job on stock heads/ stock 340 replacement springs. ) A good economical combination, with some oats under the hood. Stock 318 short blocks, respond well to similar combinations.
