Had a bud with one.
We put a set of 352 heads on his 390 and it was a screamer.
Had a c6 trans and a posi in the rear,it did some large smoke screams when wanted.

As for small block Ford engines,to me there is none better when it is wound up.
Put a ignition block switch to cut spark when shifting and watch the flames come out when you are doing fast runs at the drag strip. grin
