hello people!
well, after I finished up, building my engine...with a certain degree of satisfaction It's now time to put some strain and effort in the transmission!

What I have, is a genuine 1966 casting C6 with FE bellhousing. Now, what I want to know is, how much do the C6 castings differ, over the years they were made?
For instance:
I got a remark this week, that a new "Superior super servo" wouldn't fit my '66 casting and there is no other servo upgrade either (the Ford's R-code version, is what I would like to use) for this casting?

I'm not going to blast a 1000HP at it, but I would like a HP-rebuild, with an all-over better performance, capable of handling around 500 HP and mainly street use. (I.E. no transbrake or full manual, but firmer shifts and the lower gearratio as well!)
I got the advice that a '66 casting isn't what you want to have for this kind of a rebuild...

problem is, it's what I have...and living in the netherlands, means; either buy and ship another from the states and do my work on that, or try and do my thing with what I have...guess what I prefer?!

grtz,
Tom
