I need a spreadbore Edelbrock Performer (or copy) for Vortec heads for a bit of time to perform RPM Air gap vs RPM vs Perrformer engine dyno testing with TBI configs and E-Tec 200 heads. Anyone have one I can borrow or BUY??? I'll pay shipping both ways if borrowed, obviously. No time to wait for EBay auctions, either. I have stuff for trade, too, if someone needs parts instead of cash.
