95 bronco

Got my bronco all together internal balanced motor and t18 and bellhousing and flyweel from 87 external balance will it hurt to fire it up and pull it out off barn to ware I can get it on a flout have a friend with a shop and houst to take it apart and send the flyweel to be rebalanced

I would not Start it with the wrong flywheel!

I used a 351w pilot bearing does it make a difference?  Should I switch it out for the 460 one do they sit out different?

I would think it would be to your benefit to put it together right once. Rather than wrong a few times?

I just had it handy for mock up I read about some people having to use the smaller pilot wasn't sure if it had something to do with motor never coming with standard maby wasn't bored for the bigger pilot

My experience has been as follows;
IF you are using a 400/351M bellhousing, then you use the small pilot bearing, which installs all the way in the small step bored in the back of the crank. If you are using a "true" 385 series bellhousing, then you use the larger pilot bearing. The 400 crank does not protrude out the back of the block as far as the 385 series does, so the bellhousing is shallower, even though the bolt pattern is the same.

That makes sense thanks I will switch it out when I put it back together.

What style headers should I be looking for I found a set for $ 100 for a 81 f series 460 would they work for me?

What's the length for flywheel bolts? Can only find 1 inch bolts I figured standard ones would be a half inch longer

All worked out thanks everyone here and thanks spare parts bronco for the inspection

Thank the Lord for the big block ford
