Damper and Flex Plate Problems
I am trying to replace my worn 289 with a late model crate engine from SVO. The engine I am wanting to use is a long block 302 with GT-40P heads. This engine comes with 50oz. damper with a four bolt pattern instead of the 28.2oz. with a three bolt pattern like on my '67 289. Has anybody encountered this problem? Also, I would like to know what flex plate I can use (I am running a C-4 trans).

Heres the beef.
The late model 5.0 I believe 1980 and up uses as you know a 50 oz flex and 4 bolt damper. You wouldnt want to use the old 3 bolt damper anyway because its for the lighter 28.2 oz plate. Also the timing marks are different too. Leave on the 289. Solution: You will want to use a 50oz flex plate. If the one supplied does'nt fit in the bell housing, you will need a smaller plate. The one thats on your C-4 will most likley be the one you use. (The plate must match the trans). But make sure you balance it to 50oz. Ford made a 157 tooth & 164 plate later is the AOD plate. And use a late model 4 bolt damper designed for the 50 oz plate. Confused yet? WARNING using the wrong balance will shake your teeth out. If all else fails,,,,,GOT HAMMER? Good Luck, Hope this helps [This message has been edited by mustangII460 (edited 06-17-2000).] |
