223 performance build...questions!

Thanks Paps61
Yes I would still like to have those specs.
The cam specs will also be good to know.

No problem! As soon as I get them I will let you know!

Galaxyinline, we’re you able to get all back together?

Yes, I had been driving it almost daily until about May of this year, until my "NOS" water pump...with its 60+ year old seals decided to steam clean the paint off everything under the hood with propylene glycol. I yanked the engine for clean up and repainting, and the water pump is being rebuilt. lol it's always something with old cars.

Updates?

Updates?

Yes sorry to say I was unable to get the specs on the rods. The engine builder I used was far away otherwise I would have gone and measured them myself. But just recently now that you asked I remembered I know a guy he has one sitting in his garage I will ask if he can provide those specs and get back to you! I had sent Pmuller9 a message a while back that I wasn’t able to get the measurements of the rods but he did give me the cam card if you want that info?

Just an update:

After lots of tuning, She can lay rubber

I need to get a better video than an accidental capture off my doorbell cam lol.
Oh, that's with open headers too.

Nice! torque will improve noticeably with an exhaust system.

I should clarify: Not exactly open headers, more headers with some open pipes. I put electric cutouts just behind the driver seat, so there's significant length of pipe after the headers before the mufflers. Still gives great sound for car shows but I can cork it up for regular driving. Where I've got them doesn't really feel any different open vs/closed.

I got 'cha. 18" of uninterrupted collector pipe behind the header flange = significant low end torque improvement on dyno testing. What configuration is behind that 18" of collector is of lesser to no effect, assuming it's not restrictive. A 450 hp V8 with the collector vs open header with no collector = 30 ft lbs. Going to single exhaust (V8) increased it more. The max power (HP & TQ) on a stout 351 Ford was with collectors, smooth Y pipe and single exhaust pipe of the same size as the collector pipes. All duals' configuration had less power than the single exhaust. Numbers will be smaller, but same dynamics apply to a six.
