engine crank

private message sent

I didn't see the last message before I just replied. Still not sure what is meant by counter boring and different nut.

I guess the answer on the crank is they are the same. that leaves me with trying to use the gear for the tach from the FB engine to the FC engine. the rotation would be the same it just comes down to the length of the shaft on the rear. does anyone have thee correct shaft length for the SC engine on this gear. I can have it cut down.  

thanks

In response to rhauser.
There is no gear cutting required. The tach gear on a s/c engine is counter bored. The nut is also different and is longer with a step to fit in the counter bore of the gear.

Thanks Cliff. My information comes from Henry Portz conversation long ago. I have no evidence what he told me was truth. This is one of the few things I can only say... "I heard something about that"....

Ramsey will "fit" but they are loose fitting. I have purchased the Vintage NOS Whitney timing chains from ebay and made my own 1 1/4 inch FB engine timing chain. I don't recommend this work to anyone because its VERY COMPLEX WORK... I use the wider 1 1/2 inch chain and remove several links. More than half of the chains kinks and spacers need to be removed to make the center guide moved to the new location in the stack. Its very time consuming and can end up a real mess if you miss one link. EGGE has sold the Ramsey chain for
many years. Or you can contact Ramsey and have them make your chain length for you. Last I knew it was about $300.00.

Gee Randy, that's not like you to make mistakes. We are all human and need to work together.

New timing chains can still be purchased from a Ramsey Chain in Charlotte NC

Sorry I thought I was on an Auburn thread not a Cord

The supercharged camshaft makes the differences in the FC compared to the FB engines. Its about the only real differences besides the side fuel pump and the supercharger. There is several smaller differences too but these are the big ones.
 As for the timing gears n chain. They are very different. The FB non supercharged engine has 1/ 1/4 inch x1/2 inch pitch gears and chain. It "can" be used on the FC supercharged engines but I would not do that. The FC engine chain n gears are 1 1/2 inch x 1/2 inch pitch and REQUIRE a deeper timing chain cover. Both engines used the vintage Whitney timing chains that are long gone.

There are two different tac drives, one for standard engine and different one for S/C engine.

SC crank Is counterbalanced std is not

I have a standard engine and a SC engine, I plan to use the SC engine in my car and have some questions regarding the crank. I have the crank that came with the SC engine and in looking at it with the standard crank both seem to be the same. I thought the cranks were not the same. If they are the same the gear that goes on the SC engine to run the tach that comes off the standard engine seems to be to long since the timing gear is 1/2 inch thicker. I know the gear is too thick but I'm wondering by how much the gear needs to be cut down to line up with the wider case. I would think a 1/2 inch but it is a cord. LOL. If the cranks are different then I'm screwed. I do have the correct cam for the SC engine.
