An engine change for my 'Bird

and once its all done drive bird back to CA, an idea?

IF you are talking about a landoll or flat bed to haul the bird, budget 6$/$7.00 per mile.

Your looking at over 10,000$ to move that bird from Ca to Wi. You might be able to find someone needing a "backhaul" to do it on the cheap. Say around 7500 then you will be looking at the labor, parts, and fluids for the change over.

Trying to be blunt and an honest opinion, this is not a good idea.
the BB has sat for 5 years all systems need repaired, tires batteries, chargers, etc, then an unknown used donor engine. I would ask myself, "if the used engine was already installed, how much would one pay for this old used resting Bird".
There are Birds for sale at a better price and in good condition, keep looking.
Just trying to help. Old BB owners do not like new folks to get hurt.

In WI now, modifying the grille to fit over the new CAC, I think/hope it's all good for now.
Plan on doing a repower on the 31 FC starting in June, another saga.

80+ at how many rpm and how fast is + ?

What did it take to do that ?

What would it take to do that to a 87fc-35 and how much would you put the cost at ?

Mike has a double overdrive tranny and a 300 plus horse 3208 cat. He has also changed the ring gear and pinion. No need to try and catch him.

My coach is geared for 106 @ 2800 in 6th .65 od.
87/89/sp w/ZF are geared @ 82 in 5th that's .8 I believe.
That being said the FC drive shaft is too long and complex to safely exceed 80 by much, been 90 a time or two but the drive shaft thrum gets right scary.
75 is a good cruising speed, and it's the speed limit on much of my WI to ID commute that takes 3 days.
Doing a few more calcs: the sealed bearings we used to repair my Thelma type retarder have a speed limit of 3500, have to hit 135 in 6th to over speed them. Probably not an issue but shaft balance and angles are critical.
