Hey guys I'm thinking about running kb399 pistons in my 318 I have 360 heads on it with stock 318 pistons but trying to get some more performance out of the 318 so I'm wondering if it would be a good combo with porting and polishing the 360 heads and some kb399. Any insight is appreciated I tried searching to see if there was any info on this combo but couldn't find anything
Setup I have now
318 stock bore with stock pistons and 360 heads cam I'm running is a lunati LUN-10200702LK and weiand action plus and quick fuel 750
