Super Chevy did a series called "Major Mouse" using a 427 cu in with 11:1 compression, same heads and intake and the cam an edelbrock 2201 cam 234/239 .539/.548 with 1.5 rockers but they used 1.6 rockers. The result was 512hp at 5400 rpm and 570tq at 4000, with more than 500 tq from 2500 to 5000 rpm. This is the type of power band I'm looking for. Would I be nuts to try for something similar with the 427 block? I was told the 170cc heads are just way too small for that many cubic inches, but look at those numbers. The article I mentioned was from the April 2005 issue of Super Chevy.
Thats a sad engine to build for a racey car.I would want a lot more than that,using bigger/better heads
