yeah all 82 and newer are 50oz im into 5.0 also i got a 91 vert most of the stroker kits on the market are normally the 28oz though

 

also alot of guys building motors go with the vintage rotating assemblies and have the lip ground down on the crank to be able to use the late model block with the 1 piece rear crank seal and because the vintage crank is stronger and can handle more power

 

also the less external weight the better throttle responce will be. Thats why mine will be interanl balance as i said before I am a machinist that balances cranks all day long.

 

So how do you tell if your harmonic balancer is working.And do they break or need to be replaced a anytime. thanks.... Rob

 

check the balancer if the rubber thats sandwiched is dry rotted its a good ideal to replace it because the outer ting can slip and make timing the engine from the timing marks impossible

 

ML66-when you say "we" who is "we"

 

i thought when ford changed the blocks for roller lifters and a one piece rear main they changed the crank to accomodate the seal and THATS when they went from 28 to 50oz

was i wrong?

 

You may be right...it had to do with the roller blocks.

 

The 1985 GT was the first year of the 5.0L engine.

[edit] brain faster than fingers, I meant to say '85 was the first year for the roller engine in the Mustang. Duh.
