I was told this car was street ported when I bought it. Didn't really car if it was or not, it needed rebuilding, figured if it wasn't I'd have it done during the rebuild. So... is this street ported? I've looked at several pictures and I don't think it is.

 

just judging from your photo, this housing looks stock to me. opening side looks stock for sure. closing side may be modified; i really don't think it is, but i honestly can't see. clean it and look for casting flash. that will be your definitive answer.

 

if you clean off the ports you should be able to tell if it still has the roughness of the casting or if its smooth/grinding marks
