in desperate need of a 255 walbro pump it is for a sunfire i know its a sunfire but it is far from stock its n/a with 13.5-1 compression and i have a serious fuel delivery problem thx
im getting ready to swap cams and was wondering how much lift a stock set of sbc heads will hold before i have to swap out springs and other stuff. its a new cam going in so i would also like to know of a good way to break it in. any suggestions would be great. thanks
