trade a torker 340 aluminum intake even trade for a stock cast iron 71 340

I have the spreadbore 340 intake on my 78 360 motor. The 340 intake was from a Demon I think. Early 70's-maybe 73-74?? All I know is that it came off a 340. It works great with my 600 edelbrock. You do need to use a new spreadbore thick gasket or the squarebore to spreadbore adapter-on stock at my Advance Auto Parts store for around $40. The kit comes with 2 gaskets hidden in the cardboard inside the plastic casing. If you dont use the spacer- the primaries will "hit" on the intake. I just did all this last week, so I know lol.
