mattsny83 Posted April 9, 2009 Report Posted April 9, 2009 I am wanting to put a 4mm crank with long rods and 60 to 80 over blaster pistons with stock clyinders and port them and run off achool. How much horespower should i see ???? Quote
shanYE west Posted April 9, 2009 Report Posted April 9, 2009 you dont want to bore your cylinders anymore then you have to.. The gains are minimal and not worth taking away cylinder life. But.. a properly ported and setup stock cylinder 4mil should be anywhere from 80-90hp. There is some stock stroke 350's making 90+hp on alky.. but.. that porting is very pricey... Quote
