Take a look at my dyno sheet. This is a 470" engine with an unported weiand tunnelram on a set of 906 heads. Running 14psi with twin te44s on regular old pump gas and no intercooler.
This is chassis dyno, so the converter does play a part, but this is what the tires are seeing.




wow! that's good power... and right around the rpm range we think this one will make power and torque at too! got any pics of that thing?!
