[Newbomb Turk]

Can you post a link please. I went to his channel and looked for a title about main caps but didn’t find one.

Yup. I’ll see if I can find it.

The new owner of Pro-Gram Engineering, Billet Speed Works, can make the caps if you contact them. I had a complete 340 2 bolt set made last year. Be forwarned, it will take several months and are NOT cheap. You can opt out of the billet rear cap and save a good bit. But if youre gonna go through the trouble you might as well go all out and do it right.

I only did it because a production block is significantly lighter then an X or R block. If youre not confined by a particular class, I would go with the X or R block.

curious on the cost? they look expensive. what was the final cost to have it all done, (engine machine work cost )

Caps were $900 + the $100 or so for the ARP stud kit. I still have to bring the block to the machine shop.

What is your process on how you install the main caps?

go right here to Hughes and read it.

You wouldn't be nervous those roll pins would work their way out?

Put an LS in it. Six bolt caps.




Just kidding.

I know what you're saying I feel the same way. I just need to decide how serious I am.

I spoke with Kent today and he does not do the caps individually any longer . He feels it compromises the integrity of the stock block. He stated a stock block could not handle any more than 600hp either way. He suggested I purchase one of his blocks and have the machine work done by a reputable machine shop. He figures the cost is in the $6500.00 area complete.

When I asked him about it I specified for converting an R or X block from two bolt to four bolt.

Those things do look like a thing of beauty though.

I asked for his 2 bolt caps for my 360 block. Kent was very nice about it and expressed his thoughts on how he thought the stock block would be compromised.

Nope.

I thought all R blocks ARE 4 bolt blocks.

 

[Newbomb Turk]

Nope. There are 2 bolt versions of X and R blocks.

You are better off starting with a 2 bolt block anyway.

The Ritter caps move the register to the outside of the outside bolt.

we have a R3 block that was 2 bolt then converted it over to 4 bolt.

IMO if you need to replace the caps, you probably need a better block. That being said a set of main studs and a thorough deburr and detailing of the stock caps with a cartrige roll goes a long way to improving a stock block. Light weight parts, a good balance job, and staying out of detonation are your best friend.

I have a set of the pro gram 2 bolt caps on my 340. Nice pieces

I had a 2 bolt X block with studs.
That motor is still together to this day. It’s been as quick as 140 mph at 3220. That’s making some steam
