Title: Thinking about swapping out for a 8v71 and a 4speed....Thoughts
Post by: John316 on April 01, 2013, 04:45:10 AM
Not much else to add? Found a deal on 8v71 and a four speed. The tranny is supposedly in good shape, but the 8v71 would have to be rebuilt (came out of an old truck).

That would give us an opportunity to get rid of all of the electronics on our current S60 and b500 tranny. At that point we might look into running unfiltered straight veggie oil in in and used motor oil. Could save us a bundle on fuel.

Anything else we should consider?

Oh yes, I would consider putting Google Nose on it eventually http://www.google.com/landing/nose/ (http://www.google.com/landing/nose/) Might be pretty cool.

Are the 8v71's and 8v92's much difference in size and weight?  If you gonna take that 60 out go with the gusto!

Wing to help traction! With all that extra power and low gear it would be a wheel spinner. Bob

Actually, may not need to be rebuilt. Looks pretty good.

    Just "minor finish issues" -- that'll buff out!

I have a set of slicks for that puppy when you make the change. You'll need um when you drop the proverbial Hammer!

Good points and thoughts all around. Bob, I like the wing idea. Probably be needed. Muld, let me know when I can come pickup your slicks, will need those for sure.

Thinking of painting it before install.....thinking silver.

Put a good paint job on it and it should run just fine. Obviously this is from a GMC Astro since it has a GM air conditioning compressor on it and the low profile turbocharger. 8V-92 and 8V-71 are the same block and head external size. The only difference is the 8V-92 has a large vibration dampner on the front of the crankshaft (like a small flywheel) that keeps it from easily being installed in a V drive.

Yes changing to the 8V-71 will be one way of having a mechanical engine. It will also be a way to loose 2 or more mpg and about half the torque. If you change it out, let us know-we'll take you directly to the looney farm-and this from a person that has his birthday today. Good Luck, TomC

John,

Why not come down to Florida and we can exchange our engine and trannies?

I know a lot of nay sayer's say you can't put a straight engine in a V-drive like my 4905, but I think I have it figured out for both of us

Since I am only 96" wide, I can modify the tranny service door to let it hang out a few feet.

Only folks who might complain are bicycle riders in the share lane, but I doubt they will make it to a phone... :P

Happy Birthday Tom.

Cliff

I think it's a great idea and that you should go for it.  But do it today, cause tomorrow it will be a stupid idea.

That small ac compressor also means it might have come out of a GMC pickup. I think GEO Metros also used that combo with a larger turbo.

LOL, fun thread. Had quite a few great chuckles myself. Florida Cliff caused me a real laugh ROFL. Just stick it out the side....good one.

Happy Birthday, Tom. Turning 79 today? ;D Very astute observations. It for sure had to come out of that Astro, no doubt about it.

Have fun you guys.

John,

Take your meds...

You actually had me for about two minutes yesterday. Need to move the coffeemaker closer to the bedroom. Caffeine helps expose pranksters.

T'was funny, I'll give you that

Rick,

LOL, fun stuff. Actually, I could have probably switched with you, and you might have been okay with that.

I was thinking about swapping my 8v71 for a 4v71 so that my fuel usage would be cut in half. ;D

Now that is brilliant, Ed. Smart thinking. Whee, think of the possibilities. LOL

When the center bore or the bull gear goes on the 60 series you may wish you had a 8v71 when DD gets through with you lol

So John remember we want lots of pictures! ;D
Do they make a 2V-71 because we were thinking of welding one to our 6V so we'd have a real motor that can actually move to coach. ;D 8) :o

Uhhh... Florida Cliff:

I am only posting this because of my concern for your well-being.

With all due respect, my friend, If you are '96-inches wide', you might do wonders to your fuel economy by going on a radical diet. And letting your 96-inch-wide body hang out of the tranny service door might get you injured by those bike riders you are talking about.

And according to this sign, you are putting yourself in more danger than you think!

Just sayin.

Hey Budd,

My Doctor said as long as my waist is in a multiple of 5, I am OK.

So 96" is just fine.

By the way, who has ever seen an overweight bus driver? Yeah I thought so.... I rest my case.....
