427 Motown In!!!!!
It was everything not fitting like any custom motor. The ATI damper had to be honed to fit over the crank.................
Here is the other thread if you want to look at it:

Anyway here are a couple of pictures. It's fully studded Motown 427 with .021 Flatout copper head gaskets. I had these AFR heads sitting new in a box and decided to put them on. They are just the 2.08/1.60. AFR told me that I could reach my HP goal.
Well anyway in the pictures you can see how much smaller the ports are than Dart 227cc heads The solid roller lefters are the Crane Pros.
The studded head picture was when I was setting the ATI damper spacing to get belt alignment.
My old 383 in the shipping box :o

You need to add a "/" to each "[img] at the end of each pic url.
The end of each pic url should have a "[/img]"

Did you guy's even notice - I use light grease on the Felpro intake gasket on the intake manifold side. It's been on for year and 5000 hard miles and came right off. I've had racing temps over 230 degrees for hours on end.
The total of 5000 miles was mostly done in two and 1/2 days of driving. 3000 some miles in two days round trip from Reno to Mount Rushmore and back. I drove up in one day - parked it and drove back a week later by way of a bunch of Colorado national parks

I just keep looking at the quality of ports between the ARF 210's with CNC.......... Then look at the Darts. Bigger and really port matched to Felpro 1206.
I had a real hard on for AFR and talked to the CEO about the bougus products. We worked it out and he said that I could have got the AFR full CNC 60/40 valve arrangement AFR 227's at cost. Then I would have had to sell these Race ready 210's that had been flat milled to 64 cc and all done up.
You can't bad mouth vendors on the forums It just gets me some times. I just didn't have another couple of thousand to spend and having heads just sitting in a box

I use that spray red Permatex on one side and grease on the other.
My buddy with the hot 68 camero and 408 BBC uses a Holly HP920 or something like that. It was setup by the local "Carb Shop" anyway I thing that's the business name. He helped me on and LARS pointers how to get my Demon working. I'm going to run a 825 Race Demon I used it for a short period of tim on my 383 ci. ........ In short words it was to much even with it's 7500 rpm red line.
IMO - For the dyno you can get great numbers with 1000 cfm. In the real world which is 99% of driving time smaller is better.
I even considered less tha 750 for road racing. Your powering it through a turn and your only at less than 4200 rpm. Kind of off and on the gas depending on rear slip. Then you 100%throttle and you can feel the power coming as rpms rise. Maybe in the same gear you only get to 6400 before the next turn and your on the brakes. Your never using the max CFM except on the main straight.

Just a picture of dialing in gauge - or should I say verifying the Piston to deck height VS the degrees on the ATI damper. The Wiseco pistons came in at -.020 and my copper head gaskets at .021 give me a quench of .041
Wood blocks under all four tires and lawn chairs for my beer drinking buddy's. Half inch drive air socket on the front of the damper installer to run it it to length for the pulleys to match up. Timing cover is two piece with roller button Chrome for Roller cams
