I'm lookin to put the largest blower pulley I can on the crank. Need an accurate measurement from the center of the crank snout to the center of the cam std location not raised. I cant get in there to get a good reading without removing a bunch of stuff. I'm hopin I can get a 89-90 8mm in there the fuel pump drive had been cut out for max clearance. Dont want to buy a pulley to find out it won't clear. Thanks Craig

I have a 99t on one of my engines. Uses a RCD fuel pump ext that I sleeved and then milled for clearance.
I can send you pics of that or even send you a 90 and 99 tooth pulley to use as mock up if you want ?

I have the BBC blueprints at home, if you want the drawings, sent me a pm with your email address and I'll mail them to you !

8mm pullies are measured for the most part as 60t measures 6.0, 80t measures 8.0, 89t measures 8.9 etc

It's been my understanding that the dimension in question is 5.152" (Gen 2 blocks raised to 5.552").
