i respect em all...but in the end...im my opinion there is no replacement for displacement...i mean i know guys with heavy ass old school chevy's and fords with big block all motor's turning in the 10s and lower with a power adder...i have never seen a 4cyl or 6cyl import turn those times without serious work...and a huge power adder such as turbo or nos...or something so in the end motor to motor wise with no power adder there is no competition...and alot of the import guys i talk to that are building crazy power and turning crazy times...they say they have to do a basic rebuild every season...i mean logically that small of diplacement cant hold the high horsepower and torque as long as a bb or sb domestic can.
