rick i have a square 351 lower and a round 351 lower that i ported out to match my home made upper i have only found one at the wreckers but then i stopped looking it was from a late model f150.

Is there anyway to tell by looking at the intake if it is square or round? I will have to go hunting at a local srap yard I guess, I want a square lower so I can use my Holley upper on the 393/408 I plan to build, it will either be n2O guzzling or have boost.

Thanks A lot!
