What's the deal here? Who's used it besides Jasen? What's the better route to go? Drilling out the crank or using the adapter? With keeping the engine under 400HP.

I'll be using it or one like it and mine won't be under 400 hp. Should work fine, basically just keeping the input shaft straight, shouldn't be a lot of force on the bearing itself.

If your crank is out of the motor and you know a machinist that can do it, Id drill out the crank. But they need to know the specs and they have to get it right. Theres no fixing a badly drilled hole.

My experience with the adapter bearing:
I used the Mondello's bearing on my 330 (originally auto). The 330 had a badly drilled hole in the crank. It was not centered and never would have worked with a regular bushing.
Using the adapter bearing and no bushing in the hole, the tip of the input shaft does not touch the crank at all.
If I did not have that badly drilled hole, the input shaft would have needed to have been shortened. I would not suggest that.
I read somewhere (don't think it was this forum) where they used a portable drill press that mounted magnetically to the flywheel and then they aligned it to the hole just right.
I guess, if you are not going to take the crank out and get it done right, the less pretty way of getting the job done is just drilling a big enough hole and using the adapter bearing.
(lastly, I have nowhere near 400 hp so I cant comment on that).

Theres no fixing a badly drilled hole. Actually there is, but it's really expensive. A very good machine shop that restores engines can fix a crank. This type of repair is done all the time on very old engines for which there are no parts available. |

Hey Dolzinnig:
I noticed in your sig line that you own a 1973 Chevrolet Firenza CanAm, that's a really neat car. A sailor that lived in our neighborhood used to own one of these as well. Now that's a car you just don't see everywhere!

Big Mike, It's quite a handful, I tell ya. Got a flat cam right now. Weighs about 2500 lbs. Kinda like putting a Z28 engine in an RX2. haha. -grant Grant: I saw a car like this sometime around the late 70's early 80's, before 81 because it was before I got married and that was May of 81. This was in the VA Beach area, the Pembroke neighborhood to be exact. We moved back to the DC area from VA beach in 1968 (my dad was career Navy), but my oldest brother stayed in VA Beach and never left. I had gone back to the old neighborhood to see my bro a few times and saw the car then at this sailor's house. This particular sailor was a real car guy and used to race a 442 at the loacl strip. He had this Can Am when I was there in the late 70's early 80's and before he had that car while I still lived in VA Beach he use to own an 66 Arcadian which was a Canadian Chevelle. This guy always had odd cars. |
