Hi, I've read the 1st thread in this section and read up on setting pinion angles, etc. but I still have some questions. I'm putting a TKO 500 in my '73 AMC Javelin (street car). I didn't bother to measure the stock setup and now I'm trying to figure out what angles I want everything at so I can fab a tranny crossmember. Here are my questions:
Currently pinion points UP approximately .8 deg. The engine is pointing DOWN approximately 4 deg. The engine cannot come up anymore without clearancing the tranny tunnel more. I'm trying to figure out if that's what I need to do or if I can get the angles equal and opposite by adjusting the pinion angle...
1) is 4 deg DOWN ok for a street engine?
2) If not, what's a good angle to set at? If I need to get to 3 or 2 degrees I'll need to cut away the tranny tunnel more.
3) Is it a MUST HAVE for the pinion to have an equal and opposite angle from the engine? Someone on another forum said my 4 deg. down eng. and .8 deg up pinion sounded fine and to just put it all together and see if I get any vibration...
4) Is 4 degrees up an acceptable angle to put the pinion at?
5) If 4 deg. up for the pinion is ok then should I set the eng. to 4.8 down and stack (2) 2 deg wedge plates on the rear? Then I'd have the eng 4.8 down and the pinion 4.8 up.
Whew... thanks in advance for any insight you guys can shed on this topic.
