Started my 4.7 Stroker build today.

I just started my 4.7L stroker build today for my 2000XJ. The build is composed of a bunch of parts, the main ones and machined block that I got from Russ Pottinger, including a Scat stroker crank, a ported Edelbrock aluminum head, custom pistons made for Russ Pottinger that match the Edelbrock combustion chamber, ported intake, connecting rods, HS Roller Rockers etc. Special thanks to Cal and Mark who are helping with this build. This is my first engine build, and it is great to have fellow members that I can learn from!

Laying out the rods and pistons - and putting them together




Getting the rings installed -and checking the piston position with the combustion chamber of the head





Cal showing me how to install the piston correctly and then test the clearance of the rod bearings




Installing the pistons - you can see how the kidney shape of the piston is directional based on the combustion chamber shape for each piston position.



Pistons and rods are all assembled in the block - that was it for the day, I made some good progress for it being my first time doing any of it!

Very cool.

I'm jealous.

It should be at 10.5 to 1 -

Awesome. I am picking up all my engine parts next week from Russ. Maybe over Christmas I will have it all built.

Your going on the high end, what are you doing for tuning?

I thought with an aluminum head, you would go a bit higher on compression?

No, but it may necessitate running premium. When I did mine I worked with Russ to keep it in the 9.4 range so I would be able to use regular.

RCPPhx is spot on. I will need to run 91 octane in the engine, but don't want to go any higher than 10.5 to 1. Cal tried running up around 11.5 I believe and had problems with it. If you run higher than 10.5 even with premium you have to pull so much timing out to alleviate pinging that you start reaching a point of diminishing returns.

Ron, I am planning on having Mark and Chris tune it for me here in LA.

That will get it done, when I did mine Chris was definitely on the list of 3!

I did the same. I did not want the $ for gas. Mine will be a road going, with light trials. I do have a Viper coil planned. I'll be coping your bracket or at least use the idea.

If you didn't already I would p/u the Screamin Demon coil. I was able to open the gap on my Champion plugs to a safe .047" gap.
