Hi Rowen
Best of luck with the car & engine.
John Beck really knows his stuff.
The compression appears a bit high to me,
but I wouldn't worry about the cam at all. 
I'm sure you'll be happy with the result.
Are you going to try the dual quads too?
Best
Jim

Congratulations, that’s a good looking motor and good looking numbers. Should be a real pleasure to drive when the tuning is finished (if needed) in the car.

Almost 1hp / ci is great.
Were any other carbs or spacers tried?

Charlie, We did try a 2" spacer and it didn't like it much. The low end, which is where I will spend most of my time, went away rather significantly. As much as 10+hp and up to 35tq. I am very happy with the #s so we stopped. Not to mention dyno time ain't cheap. I think it will be a fun ride. Miker, thanks, I think it's kinda pretty myself. Yup, some street tuning in sure will be in order and I am hoping for a smooth dial in. Jim, not right now as I want to get the car up and running and get the bugs worked out of all the other things yet to dial in, drive line, brakes, elec, seats,..etc..etc. after she is road worthy and all the extraneous things are right then I will maybe start playing with it. Here's the sheet with the spacer...

I would expect the HVH spacer to hurt low end in most cases.  What you did with that is make a great dual plane manifold into a mediocre single plane.  Try a 4 hole or divided spacer, something that preserves dual plan functionality, and I bet your numbers will pick up.  I think there is more in it with tuning.

I also see that the mixture was leaner at the lower end of the test range with the spacer.  So the loss probably isn't as great as it seems, with additional tuning.

The spacer was a 4 hole (tapered). There may well be more, perhaps much more, time and budget dictated the stopping point. I'm happy with it and the budget didn't take any extra cost hits. More tuning will be needed once in the car and the dyno was more for break-in and fun for me. This whole process has been and continues to be a gas! I'm having a ball!! Next pics will be of the install. Stay tuned.
