looks like 1.266 is the CH listed for the combo, how close do they come to the deck with a 6" rod?

If you are fool enough to believe the deck of a 351C is 9.2, then the deck clearance is only 0.009"

In reality its more like 0.024" deck clearance

Its in my charts if you study them .... little known fact

R code motors = 9.206 deck height

All others = 9.215" deck height

George's number for other blocks explains a lot. I cut .016 off the last block to get zero deck.

Just note something I learned from Scat - just because the numbers work out doesn't make it a viable combo. I asked about the same thing with a neutral balance, Scat tech said "won't work - rod too short to balance". 6.125 rod, custom piston. Just keep that in mind.

I remember a conversation with one of their tech guys about balancing a forged Cleveland crank and they told me that you would just need a piece or two in each end....yeah right....if the rods were made of cardboard.

The few motors i have built, one of them having TRW Flat tops, all needed 32 thou to get zero deck. These were 1981 Australian blocks.

I specifically asked for a 3.85 arm W steel crank, C type piston, neutral balance, rings and bearings. $2200 was the rough quote and that rod was required to make it work - according to them. When I get to do this next engine, I'd like a crank that can be fixed or fairly easily replaced. Believe me, I'll call you and/or other real time experts when the money is really on the table for it.

I did a neutral on my stock 351C cast crank with stock 5.78 H beams and light probes (stock pin height), took 8 hours and 4 pieces of Mallory. I'd like to not have to do that again LOL.
