I have a set of 4mil ported stock cylinders drag ported for Alky.. Port work done by TZracing on here he is a stand up guy and does awesome work, im sure there are several on here that will vouch for him and his work! Cylinders are fresh at 64.5 bore comes with pistons, domes and of course cylinders. 18cc domes cut for the 4mil 200psi, set up for .015 base gasket. Bore is in great shape as well as the domes and pistons. This set up ripps just ask him as they came off of his personal drag bike. looking to get $450 shipped for everything.
