Timing Gear Drive
Trying the Cat Gear Drive on the 318 based 402 I am putting together right now.
Issues that I have found.
1) There is only 1 hole that needs to be drilled and tapped it is on the lower right bottom of the plate.
2) Very hard to degree the cam by skipping teeth on the cam gear only.
3) The plate will need to be clearance'd so the timing cover will go on all the way and mate with the block.
4) You will also have to cut the V out of the cover to clear the drive before buttoning it all up.
For example my cam card says installed ICL @105*
Using the standard key it came in at 103*, skip a tooth and it came in at 115*, put in a Mr. Gasket 2* key "that fits VERY loose in the cam" and is really 3.5* comes in at 106.5*, So I ended up at straight up rolling the cam gear 1 tooth back counter clockwise and using a Mr. Gasket 4* Key to bring the cam back clockwise and ended up at exactly 105*ICL, I found out that the 4* key is actually 5* and it fits very tight in the cam just like the stock key. FWIW
