i agree ryan..the moroso calculator seems to be exactly in line with riders dyno,and as such is a good barometer...

if i plug my 134.40 pass and weight into the calculator on this site,it says 633 at the tire,add 20 percent for driveline,and you would have a large number

a few years back(and some may remember it)mopar muscle had a feature article called"smallblock stomper"..they ran a 416 with "mildly ported square indy's"about 12.5 compression,and the same flat tappet cam that quickrunner went 10.69 best in his runner...they had a 1025 race demon on that motor that i bought from them,at the indy swap meet...anyhow,they showed 665 horse on the dyno,and said with a roller and port work,another 50/60 ponies were possible...we now know that couldnt have been true...figures are figures.....with only(at this time)a puny 618 ponies,that duster is as cheap to insure as a cavalier 4 door
