When I switched to a standard steel timing cover and got rid of the reluctor wheel I used and older style 8" balancer for a 350 with the longer stub where it goes into the seal and went to a standard width timing set, any roller cam timing set for a 305/350 from the late 80s to early 90s will work. Just spec a '90 camaro with a L98 and you'll get there. Add a couple 1/4" dowel pins to the block to locate the timing cover. The holes are in the block already. GM # 10456413 distributor gear should fit a factory HEI and work with a GM roller cam.

You'll get a sweet set of PM rods and a windage tray in there too! If you need an auto trans flexplate I have the number for that around here somewhere too.
