Hi there, I have a 521 BAE motor that I run in my funny car... I have gone 5.57 @ 264 with my screw blower. I have it built and ready to go and I have a list of spare parts to go with it like a spare rack of pistons mounted on rods with new rings. This is in Ontario Canada so it does not have to go through the lovely border "stuff". Please call if your interested Paul Noakes 519-657-9850
