Joss Engines 468ci. SB All Aluminum Ritter XR Engine

Hey everyone, as I stated a little while back in another thread, I would do a build thread on this engine when we were seeing the light at the end of the tunnel. There were many challenges in making this thing come together to what you see now. Many are wondering what issues we ran into using the Ritter Racing XR Aluminum block. I think I might do a seperate thread for that. I would first like to talk with Kent about this block. IT IS THE PROTOTYPE ALUMINUM BLOCK.

1050 dominator
Indy rect. Port intake.
Indy 360-1 245cc CNC heads
Ritter Racing Aluminum XR 48 degree block.
12.2:1 compression
4.185" bore Ross custom forged piston. -16cc inverted dome
GRP 6.300" Rod
BPE 4.250" stroke crank
Comp solid roller
277/284 @ .050"
.724"/.693" lift.
110LSA
1-7/8" primaries 3-1/2" collector

This info is subject to change as I am at home sitting on my couch and this is off the top of my head.

Looks good, what did it make on the dyno. Must be a torque monster with all those cubes.

Looks good Kenny. Have you thought about a larger tube header, maybe 2" primary with a 4" collector?

We haven't done a whole lot of pulling on it yet. It will be being disassembled to address the one last problem we are having with this block. The oil drain back is not enough. The holes provided aren't enough, and the small amount of crank case pressure is keeping the oil from draining back well.

We have made a pull to 6500, and we were seeing 100 points (This works out to 650hp) We are of course expecting much more than that out of this thing, as it is very similar to the engine in my car.

These headers are our dyno headers and not the headers which will be in the car. I could see benefit from a 2" primary, how much, I am not sure. Maybe the best bet on this would be a step because of the port size. 4" exhaust for sure wouldn't hurt. My car at the same cubes is huffing through 3" street exhaust still and the fastest it has run is with the pipes on.
