Big Block Gear Drive On A Slant?

Make sure you check the movement with a full load of valve springs on it. Also, blocks that have had the **** line honed out of them can get some of the movement out of them. When that happens, the gear tooth is shoved too far into the root of the groove.

IIRC they make undersized floaters for that situation. I've seen more than one have much more movement than a chain with slop in it.

Just bringing thread back up as @Hyper_pak asked some questions. I have changed my mind about the dual idler gears. yellow rose is right. There's too much slop to use them, so I am converting it to a single, fixed idler system. I'll post up more as I go along. I am going to modify the camshaft to be a three bolt, like the big block so I can run the cam button. Also to convert to a fixed single idler, I am going to drill the big idler gear pinion dead center with a 3/8 hole. Install all three gears on the engine. and jack them together with a .003" feeler gauge between them. Next, using the drilled pinion as a guide, drill a 5/16 hole through the front of the block and tap it 3/8 24. Then finally bolt the pinion and large idler gear to the front of the block. Since there's minimal lateral force on the idler gear, it should work fine. I'll be adding pictures as I go.
