I don't personally know of anyone moving enough volume of these to walk-in customers that they are unsealing boxes to sort through them.
It could happen, sure. I would guess that the "+" blocks are being held back for their better customers and/or house karts being a bigger problem. The average blocks get built and sold to others. This was a regular deal back in the early flathead days.
Has anyone heard of any dealers charging more for the "+" blocks? I would think that would be a big red line to be crossed with Briggs.
Power Distributors will definitely not allow you to sort through the at their facility, this I know.
I don't know that it's worth it from a "0" block to a "+3" block since not one of us has the capability to accurately measure that, but I would disagree with Jimbo (I know, not the first time
) that -3 to +3 bearing no difference.
Personally, I want every advantage I can get. (and so do my customers!)
Even if it's halves of tenths...a few here and a few there really add up on a sealed spec engine.
It's sort of pot-luck when you get one that's right on the max pop-up, but it sure does make you (and your customer) smile when they see that little "3" on the front of the block.
$875 complete & race-ready. This one just went to Texas.
