Boy there is really no easy way to do it with out the right tools as the cam bearing housing bores in the middle of the blocks are smaller so what ever you use becareful.

You could make your own I suppose but it would be time consuming, take a look at proform tools they have one for around $200 that is decent. Otherwise take it to your local machine shop and have them do it for 30 dollars. If you are doing it alot the tool is a good idea, If this is a "once in a great while" thing then just have a machinist do it.

Cam bearing installation is pretty touchy, even the pros have problems. This is best left up to a shop with tools and experience even if it 30 freeway minutes away by LA distance measurement.

To add an important technical note.. 4.3's use different cam bearings in blocks made in Tonawanda Ny. Than blocks made in Romulus Mi. One of the many "gotcha's" designed into 4.3's.. Look for a small "T" on the rear of the block near the rear seal attach area.
