I'm definitely part of the old school crowd that still think "there is no replacement......for DISplacement!!!
Old ways die hard, I know. it took me quite a few years to admit that modern technology IS the future today for hot rodding. you don't have to look far to see 400, 500, 600 or more HP from assembly line cars today, and many of them are relatively small CI engines. not only do they give the HP and torque numbers, but they all get 20+ mpg and have impeccable street manners.
I guess I've never really been a big CI person anyway, but I have dreamed of building another 301 SBC in a 55 Chevy post car, just to re-live my "glory days"……… but then I realize I can drop in a wreaking yard LS motor for 1/3 the money, have equal time slips, and comfortably drive it home from the strip on 1/2 gal of gas.
Now if I could just figure out a way to make an LS sound like a 60s hot rod………….. but I admit that's one aspect of a 60s hot rod that just can NOT be duplicated with modern technology.
