hello: any body ever clearanced a pete jackson gear drive ? I got one with no instructions , I got it to about .000 clearance should there be what maybe .040 between the timing cover and the gear axle shafts ? and will .100 over length push rods hurt any thing in a stock 327 ?
well I got the info on the gear drive .Any one care to guess about the push rods ?
not likely you will cause any problems with a slitely longer pushrod as long as the rocker rides across the valve head ok ..Quote:
