I think they are V8 lifters. They have to be some chrysler/jeep/dodge lifter. I didn't like the 505 cam initially because it was a cast, not billett. I.e. the same cam blank used for the flat tappet cams. The grooves are just sloppy and huge. IIRC, combining them equals a 1/4" diameter leak.

I will have to get with Clifford on this. I bought the engine built and just wanted to make a few mods. Seemed like a good start.
Welded the rods?? I am going to have to take a look at that. That could mean an unbalanced rod which means an unbalanced crank. I am not comfortable with modifications like that.
They just weld them to add to the width. I have no doubt they balanced them after they were machined. I've seen/read several builds that have used rods like that in more then one magazine. They have a pretty good rep so I'm sure it was done right.
Yeah, I checked with Larry at Clifford. It was done right. They offset the crank for more stroke. The 327 rods are Eagle GT rods. The motor was built for a "Jeep mud drag" apprently. I am going to have to open this engine up to see what all is there (rods, bearings, whether the block was sleeved or not, etc.)
Does anyone know much about the Uni-chip piggyback on the ECU? The main reason I want to keep this is because of the AW4 I have in the Cherokee.
I'm new to this forum, but I am former employee of Clifford back when Jack Clifford was running things. That said, the Eagle rods were only used on two stroker engines from Clifford. After that, we had custom Crower rods manufactured. They built the rods when they had the Chevy's in their production line. Crower just made the big end wider to fit the 258 journal for us. Then you offset grind the crank and have a perfect fitting long rod setup.
I'm sure if you contacted Crower, they'd make a few sets if a group buy was organized. Who knows, they may have a set on the shelf. Remember, we also had custom Arias pistons made to match the specs of each engine.
(This might be old news though, as I'm new to the forum)
