I wonder if a Y could be competitive in the Spec small block class that ran today?  By the power numbers, I think so.  I wonder if one could get by on a technicality since Edelbrock do make John's heads and Intake.

Oh, nevermind.  in the rules, minimum bore 4.00"  That would be hard to pull off.
Min rod journal of 2.00", so no 4" stroke crank.
"OEM replacement production style rocker arms only."  I guess that means stock rockers - no roller tips or higher ratio aftermarket.

Did you guys see the intake manifold on Jon Kaase's engine?

Very interesting.  I wonder if anything has been reconfigured in the heads or manifold.

We've seen something like that done for a blown motor.

Does anyone have a explanation how a SBC intake works on a Y head? Those spacers must be pretty trick.

My thought is that he reworked the inside of the manifold.  But, this is Jon Kaase, so maybe he found a way to make it work with the port mismatch.  We should find out how well it works today!

That would be interesting to know. If the spacer could be made relatively cheap that would open up a huge selection on intakes.

I bet on reworked manifold too.
Opened up a whole middle wall of runner pair and welded up a new horizontal wall if that is not against the rules.

Do that thing to heads might be against rules and might be quite impossible.
