Based on what you said, you don't like long rod engines or just not in longer stroke engines? The longer rod engine will have a marginally lower dynamic compression ratio (lower by 0.1 to 0.3 compression points at the extremes) but I generally like a longer rod in a short stroke engine....

just remember before you hot rod it too much you have taller gears, so dont do the "too much of a good thing" you need the right rpm's so the engine can move all the extra fuel and exhaust.

I like the RR to work with the use we're going to be at, if we aren't hanging at 8000 rpm all day then i find no reason to keep a long rod and hurt the motors perf in the low and mid where it will see more use.

For example everyone building the b motor with the rb crank, none of them are building for superspeedway use, so why lose that low and mid power for the upper area they aren't going to be in, the other thing is piston speed and that also helps in quench.
