You need to mock the engine up with that cam gear and the crank gear you intend to use to see how they fit. There is no other way to do this correctly.

There are 14 different pitch cam gear that w ...

Weld the spider gears together. Not much cheaper than that, and there isn't much real load just spinning the tires. It will make the tires chirp around corners and in parking lots unless you over fi ...

Most of the factory uncut VW stuff I have measured was .011"-.014" oversize on the bore. If you only had .003" clearance you wouldn't be able to get it all together without something b ...

It will make the hex bar crooked, and the drivers side arm will probably hit the shroud. I actually prefer offset linkage with straight manifolds. You will need to do some clearancing on the front s ...

I like a nicely built single port.

Post some pics of the valve bowls. The bowls and the valve job are where most of the gain in a SP head happens.

The intake/exhaust flow ratio is pretty clos ...

Yes. Every bearing for oil clearance. It will take you hours and hours to do. You will also need to assemble and tear the engine apart many many times. This is all part of doing it correctly, and ...

If I'm using a new crank and new connecting rods do I still need to measure the bearing clearances?

You ALWAYS need to measure EVERYTHING!

A .0015" either to big or too small can cause yo ...

I think the super short curvy intake manifolds might be the limit of the whole engine. With the 2110cc, I am pretty sure you will be past the 125hp limit on the exhaust.

If you are buying a crank, the 76mm, 5.5 rods, and B height pistons is a pretty easy combo. The case doesn't need much more clearance work, and the deck height is usually right close to a perfect .04 ...

I look at the chamber the same way as Torben. It needs to be an extension of the port. The biggest bottleneck in a port should be the curtain area and getting the air past the seat and around the va ...

Throw those F'in swivel balls in a lake somewhere so no one ever has to deal with them again... I can't see any engine that needs .200+" in shims.

There is almost no way to get the swivel b ...

CB hex with a bearing upgrade is just about as perfect as it gets off the shelf. I prefer the offset manifolds and matching linkage over the straight manifold setup. The straight manifolds use a 1&q ...

The only way to know is to just mock is up and measure. Don't bother trying to guess. Way to many variables.

Sounds like your parts pile is getting better and better.

If your crank is a 78mm, you are going to need B height pistons. Do you have the box for them, or are they on an invoice? They usually ...

I agree with Dave and Torben. No need for a box.

On my 2332cc in my bus I have a 6" hose with the mini filter on it. All on a stock OE breather tower. Works perfect and never leaks.
