hectic, if you're planning to use an automatic behind the 153, please reconsider. i doubt if you'll ever be happy with an automatic; they will really do much better with a 4, or 5-speed manual tranny. i had a 153 in a datsun pu, a chevette and a chevy II wagon the chevette had a turbo 350 and the other two had powerglides. this 181/4-speed has proven to be the best/most powerful of 'em all. if you'd like some ideas of modifications that have served me well, during build-ups of 3 previous chevy II 4-bangers, drop me an e-mail at drh@digital-link.net
