The HVH is not 4-hole. I understand that it does have 4 holes on the top but it is effectively an open spacer. It is better than a basic or typical open spacer but it is open, nonetheless. The 4-hole spacers are cheap, so definitely give them a try once in the car. You probably will feel a difference. Here's the vid

Rowen: In your general description of the engine, there was no mention of block milling/decking or milling of the "G" heads? If that wasn't done, it's possible your compression is lower than the piston description indicates. If that is the case, a change to a milder Cam might be a good idea? Any change should be done now as it's not easy on a Y-block.. Just thoughts to kick around ?

The block had been decked prior to me purchasing it. John did check the deck height before doing any assembly. Not sure if I should post these next couple of pics or not. Let me say that I am COMPLETELY satisfied with the results achieved by John with the parts I supplied him for that ol iron headed Y-block. I wanted a streetable pump gas motor and that is what has been delivered. Within a few tenths of 1 hp per cube was my goal and as far as I am concerned, achieved. So, having said that here is a list of labor and parts:

I think you've done real well with numbers from a very honest Dyno.
I can't wait to see the car when finished. Best

Jim, I broke down and bought John Mummert's dual plane. The numbers it makes are just un-matchable with any other I looked at.

Merry Christmas to you gents!! Got the engine in over the weekend. Couple minor issues fitting those headers but got em in. Haven't fired it yet but boy howdy in my humble opinion, it looks perfectly at home! Drive lines have been sent out. This weekend I finish up the disk brakes and plumb the fuel lines. Jus a little closer...........
