replacing cam bearings

[1986]

I bought this one...

http://store.summitracing.com/partdetail.asp?part=PRO%2D66794&autoview=sku

and all I had to do was turn down the blue block a little so it fit the engine block since it was supporting the tool in a smaller bore than one in the 350 blocks.

The last front bore of the 350 block is the largest bearing IIRC but with a 60* the two centers are the same size and the front and rear are the same size... on the 350 the fifth front bearing is larger still so you can get two different sized ones through that hole to install them. if you were to number the 350 bore sizes 1-3 (3 being the largest bore) I think it would go, 2-1-1-2-3 where a 60* only uses sizes 1&2 so its 2-1-1-2

OK i have a tool now, almost the same as the one on that link. just diffrent colors, i have new bearings. but im STUMPED on how to get the old ones out, em i just supose to knock em into the block? will i be able to fish em out?????

i saw a video on YOUTUBE but its on a ford block and you fit your hand through the bottom and take em out and put em in.

help!!??

Before you pull the old bearings out, look at the position of the oil holes - they should be @ 4 o'clock as viewed from the front of the block. Fit the tool thru the block - rear to front, and remove the front bearing. Next remove the second bearing same as the first (bearing will fit thru the first bearing hole as the OD is smaller than the bore). Just reverse the procedure for the 3rd and 4th bearings - front to back of the block, remove the rear bearing first, then the third. Just take your time and use caution when installing the new bearings, make sure that the oil holes are aligned to the oiling grooves in the block when your done. D

i dont see how i can do that with the tool i bought. its just like this one http://store.summitracing.com/partde...4&autoview=sku

ok i got them out and installed 4-3-2 with the oil hole in the 4 oclock postion just like the old ones, but i dont remember which way the front one goes, i figure the grove on the OD has the point to the timing chain, but does that hole end up in the 4 oclock position? since that bearing has 2 holes?

Ok, i'll bump this up since I am in the process of putting in cam bearings. I bought SBC bearings to use. The largest bearing I have is the only one with two holes, and according to 3400-95-modified that's the one i'm supposed to toss??

Do other SBC sets have two bearings with two holes?

Bump..

Hoping to put these in tonight....

No they don't you have the right set. Just install the ones that fit. Toss the odd sized one. in the 660 block the front and rear are the same and the middle 2 are the same. There is about a .010 difference in OD so you can pass the middle bearings through the ends.

In the set, the odd sized one is the one with 2 holes in it. 1 is different then 2&5 are the same, and 3&4 are the same

I measured:

#1 2.025" (this is the one with 2 holes in it)
#2 2.015"
#3 2.005"
#4 2.005"
#5 2.015"

Since I started this other thread, I will keep that one going and let this one fade away.
