Well both Yay and Nay.
Some cars looks pretty good with bigger than 16" wheels (like '67-'69 Camaros) but some cars don't ('50s cars with those huge rims, yuck!) . And what came with those engines well I'm guy how respect old school and like it most but sometimes it's nice to see car with LS engine under the hood (like '80 Camino for example) than that 140 horse power 305 under the hood. But theres also those cars what don't need plastic covered LS engines or something new under the hood. Like all 50's cars.
