With cubes that big and compression that high for the street, it looks like the cam is too small. 248@50 is small. Why an even pattern. We all know the exhaust side of an FE is limited? Even with the Edelelbrock heads. Not enough duration, therefore not enough HP. With that amount of duration, I suspect you might have detonation problems. Not enough to bleed off.
FYI, the first dyno pull is usually right around where the hp will end up. I rarely see 50 hp in the tune of one of these unless there was something drastically wrong like a bad carb, distributor or loosing a cam lobe, etc.
WHAT WAS THE MAX TORQUE?
WHAT RPM DOES JOE FEEL IS MAX?
5800 IS LOW FOR A MAX HP.
DID HE RUN IT UP HIGHER?
WHERE DID IT NOSE OVER?
THE MUFFLERS COULD COST 50+HP.
JUST WAIT TILL YOU PUT THE LITTLE AIR CLEANER ON.
THAT WILL COST 40 TOO.
