90.5 mm bore.. its a 78.4mm crank...

I used a TI 90.5mm piston inside a Nikisil plated, rebored 90mm (1700) TIV cylinder.

CR = Efficiency! It only has .035 deck to boot!

I plated a set of cast iron cylinders for Jake for that project- trying to improve the wear and oiling properties while getting a little more power from the reduction in friction. :-)

They aren' really Nickies... Just plated stock cylinders..
I am only doing it for friction reduction.

I am doing this for friction reduction as well... And also to control windage.

I thought on a type IV that the cam advance/retard was done by a selected cam gear itself, not by adjustment - no?

Yes and No, some cam companies make there cams with a 2 deg advance built in, some 0 deg, some of the type lV cam gears have a 2 deg advanced built in, some one may have there own gears made with a 4 deg advance.

There are the adjustable strait cuts, Magnum gears, makes strait cuts for type 1, and now makes them for type lV, $225 Fat performance has them made by Pauter $325.

I didn't advance the cam at all. Looking at the picture it's not as clear as I would have liked but, the dot on the cam is between the dots on the crank. If there is any advance built into the cam I'm not aware of it.

I'm back on track. 15 of the 16 head studs are in. I'm waiting for one from Charles to finish that task. The missing one is in a blind bore so I'll assemble the case.

Oil pressure relief pistons. I test fit them and the pistons are nice and free in the bore. So I laid out the pieces. It was finally time to get into the gasket kit. There is a copper sealing ring for the smaller assembly and an aluminum one for the larger

I found this old square from my dad and I used it with vice grips to tighten it. It fit the slot very well. Then a couple of taps with a mallet and chisel and it was seated real well

Allright I was following along O.K. until you got to the type1 oil pump??
Why are you using a type 1 pump? (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif)

Dave,

I think I topped your breaking the stud move.

I tightened the case down while the front cam bearing was not set properly... thinking the case was binding up a dowel or something. Well, I cracked the front cam bearing journal.

He is using a TI pump because it is far superior, it came in my kit and he is using my other oil system mods based on the TI pump.

My 3 liter is running the same pump- they rule. Tons of volume, better pressure and less HP draw from the engine..

Still making progress. Here's something that's easy to overlook. Thermostat cable pulley. It goes where the Q-tip is.
