I had a local shop build a 422 stroker. 340 .060 over with a 4” crank. I have 9.5:1 compression because I wanted to keep the stock 2.02/1.88 J heads. I had the heads ported and they flow 255@.600. I have a non ported offy port o sonic single plane intake and hydraulic roller valve train. I will upload a pic of the cam specs. The shop called today to tell me they made a pull with a 750 Edelbrock carb and it made 355 hp and 421 ft lbs. I think it should be at least 100 more on each spec. Any...
