I'm amazed when I read how "small" 318's are. There were the 302 Chevy and ford motors that were Dz an boss that spanked 340's in their day and they all ran big 4 barrels.... 327's are not that much "bigger",,,, Just sayin. Just cause it ain't a 340 don't mean it can't run. I ran a big cam x heads milled and a six pack with a 4 speed and took my share of 340 pride in my rear view mirror.
