I've done a couple of "period correct" engines, both street and race.

I built a 428CJ for a guy in Mississippi. It had the correct CJ heads, we just did a good valve job and put some Ferrea valves in them. Used a 227/233 @ .050" hydraulic roller cam, about .600" lift. Intake was the 75 lb cast iron CJ piece with no porting whatsoever. Compression was 9.7:1. It made 422 hp and around 460 lb-ft if I remember correctly.

Also did a 427 LR 2x4 for an FIA road race Galaxie. It was a rules engine, but we used the factory heads (did some heavy work on them), the factory 2x4 LR intake, and a solid flat tappet camshaft. It was an 11:1 engine. It made 510 hp @ 6000 through 6500 and 511 lb-ft of torque. That particular engine had a $ crank, with the rod journals turned to 2.200", Oliver 6.800" rods, and RaceTec pistons running .043/.043/3mm ring sizes.
