Eventually though I would like to swap a V8 as a sort of truck tribute to my grandpa's 1948 GMC which he and my uncle swapped a 283 into.
Unless your changing the trans nor rear, adding a V8 won't give you any more speed...3500 rpm with a 6-cylinder is the same as 3500 rpm with a V8.
I'm also in the radial camp! My '56 8400 had Bias tires on it when I got it back in 1997 and the first thing I did was to put radials on it and it made a BIG difference.
My .02 cents!
