Not Ranked
3.31 rear gears with the Goodrich BIG letter tires at 26.5" tall.
2800 rpm or so at cruise. I had a roller cam and the engine was good to 6500, just wastin' time after that. 2X4 intake.
The point is: It BARELY liked 2800 rpm cruise. Sometimes I would cruise in 3rd just to get the rpm up a little bit! Maybe it was that 12.5 to 1 compression ratio?
Going with a flat tappet, less wild, looking for 2500-2800 rpm cruise range. 6000 or so max rpm (done racing I keep telling myself, liar liar). 
Gessford is recommending the cam profile based on my new 9.8 to 1 engine.
Looking back on it, I think the RADICAL center squirter drag race carbs were as much a problem as the cam profile. I switched to vac secondaries a week or so before she "blew" and it DID appear to be doing much better. In fact, it was running GREAT, isn't that the way it always goes just before they blow?
