Mike it is one of those early R3 blocks with the wrong cam tunnel. I would press in sleeves into the cam tunnel so you can use a 59* cam... yeah its a fair amount of work but if the block is cheap enough it would be well worth the work... I would assume that $800 block is the same way based on the price... or talk to the cam grinders and see if they can cut a 48* cam to 59* specs and then use the needle bearings EDIT Or check on getting a few cams made for this type of block... there are a few out there

My R3 is #003. The only issues were the main bulkheads weren't trimmed enough to clear stock counter weights, 30 minutes with the carbide. And the upper 2 timing cover bolt holes were drilled in the low deck location, drilled and tapped 2 holes. Doug My R3 didnt have any number(that I recall)... it had the same issue in the bulkhead area

I called Bullet they said they have never heard of this before but could grind a cam for $750. Not bad considering. I dont know if Bullet buys their blanks or if they make them.. but if they get rough cores they can grind anything with them... a 48* cam ground on 59* with roller bearings would be great... or even better would be a 48* block... mine was a dry sump block with a solid valley area and no filter set up

What are the bearing bores? No such thing as 48 or 59 bearing size. I have had several different bearing arrangements with 48 degree. There have been a few for 59.
What is the lifter bore spacing? 1.625 is common for 48. And 1.875 is stock 59.
The hurdle in making a camshaft with oil pump gear. Loose the gear and go external oil pump and front distributor solves problem. Order a spool and get your cam ground.

Leon, I'll measure the block when it arrives. He didn't know. What does a guy have to do about a intake? I have w5's and a Indy intake. Can a guy mill enough off a standard deck Intake to make it work or what should a guy do? Thanks

So you need a 2 in Babbitt bearing cam for that block. Or is it set up for a 50mm roller?

Port match and slot bolt holes. If you plug and change to 48° you will have to cut the heads and intake for pushrod clearance. Personally, I would keep shopping and find parts that mate.
