The 351c.net forum has a topic on this and I was going to post this info there, but I have been waiting for registration authentication, so I'll post it here before I forget all the details.
In episode 32 of RoadKill Garage, David Frieburger and Steve Dulcich build a 351 Cleveland Stroker. Dulcich calls it a 406 at some point, but I think he meant 408.
They use aluminum Trick Flow 225 cc heads with 60cc combustion chambers. The pistons are dished with valve reliefs to set the compression ratio, but I don't think they ever mention what that compression ratio is. Freiburger confirmed on Instagram that the heads were straight out of the box and Dulcich did not port them.
The cam is a Comp Cams solid roller. 252/260 @ 0.050, 0.659 lift, 109 degree lsa. He said the lobe numbers are 2513f and 2517f.
When installing they found that if they lined up the timing marks on the chain the cam would have been retarded. They advanced it, but it is unclear how much.
The intake was the matching Trick Flow single plane.
They set the ring gap at "24-26"
They put it on the dyno at West Tech and unfortunately never show a graph. When they first show the dyno screen it is already at over 6000 rpm. At 6300 it shows about 630 hp and 520 ft lbs of torque. It (torque) was falling, but hp was going up because it was falling slowly as rpms increased. Peak torque was 550 and happened at 5400 rpm. Peak hp was 658 at 7400 rpm.
I am considering copying this for my build, perhaps changing something (dual plane intake?) to move the torque lower and going with a hydraulic cam. I would not want to spin it as fast as they did. Changes might not be necessary if the torque curve is flat. I will see if I can catch Freiburger on Instagram again and get him to share the entire graph.
My other direction would be Scott Cook heads and intake. I like that he made these look like the stock stuff externally, but I find the ability to drive 30 miles down I-75 and pick up a set of the Trick Flow heads (right now if I wanted) at Summit Racing and walk out of the door with them appealing compared to sourcing high dollar, heavy items from Australia. The Trick Flows are based on a 2V arrangement (I think), but if they can make that much power, it's as much as I am looking to get.
