Sorry to highjack the thread, didnt mean too! Mark, im not sure what to he true specs are on my engine as i didnt build it. All i know is its a 326 with a mild cam, 4 barrel, edelbrock intake...yada yada yada! Almost put a tremec behind mine, bust nostalgia got the better of me and i put an m20 behind it.... Lots and lots of fun!
