[quote=gregsdart]The rest is easy, right? Well. Not quite. The Jesel belt drive spaced out the crank trigger pickup bracket. No problem. Make a spacer, done. BUT the injection pump is now interfering with the extra oil line for the dual pickup system. And i have no idea why the 255 mm belt that drives it is now too tight [quote]

This year while working at a race engine shop I have installed 5 Blower Shop "baby blowers" on big BBC engines, all over 600 ci. Some were iron blocks, some alum, all were after market. Each one was just a little different. The blowers and related parts (pulleys, brackets, ect.) were mostly bolt on, but when it came to vacuum pumps, fuel pumps, water pumps, crank triggers and plumbing for each, that was a different song. And, with most of them going into dragster chassis, I had to be mindful of the radiator clearance up front.
Easy, bolt on. Yeah, right!
