We pumped a 351 up to a 408 stroker with a :355 equalok posi and big meats .. a WORLD of Difference .. that was many years ago but I was never beaten in a stoplight contest . ha ... We could have went to a bigger displacement , but the 408 got the job done very well !! Just sayin ' We also built a 351 , stroked it to 427 with AFR heads and a bunch of "other goodies" THAT CAR was a "Handful " also and it's presently in EUROPE somewhere in Germany . Someone purchased it and had a couple of ' events' themselves that I read about later on .. These little cars of ours can be " pumped up " to a worthy street car . Cometized Chip
