Dean, this post is pretty old. It's already been dyno'd.
The block is a Dart Sportsman block. It has 4-bolt splayed caps on the middle caps. 4.155" bore, able to handle up to 4.25" stroke. The block was already clearanced and even with my 4.100" crank, it had a mile of clearance. The block itself is rated for 1200hp. It's very beefy.
The bore is 4.155". A 427FE is 4.230". A 428FE is 4.128". A 460 is 4.360".
As with all strokers, side load at the bottom of the stroke is a concern, but it's no more concern on this engine than it is on a 347SBF.
This engine made 584hp at a low 5900rpm. 555lb-ft of torque with 486lb-ft available at 3900rpm. For 445ci, the camshaft was the weak link. A solid roller with about 260 degree duration at .050" would really liven this thing up. The heads flow 343cfm, which is about as much as you can get out of a smaller port SBF head without sacrificing port velocity.
As I mentioned in the other thread, my hobby is planning/assembling engines and seeing what they do on the dyno. Kinda of a plan/experiment type deal. I'm through with this one and I'm on to the next.
