351W-SpreadBore intake manifold.

[Madgyver]

No adaptors. For a Qjet.

Is there an intake manifold available for the 351W with a spreadbore mount?
I searched and found that Offy had made them available sometime ago.

The Offy one is the only one I know of had one in high school usually see about 2 a year at the big swap meet if you really want you and no one else comes up with any ideas I could look for you it in 2 weeks just let me know they usually go from $80-125 have seen one as low as $50

Mad I just had my kid check an intake I have at the house. he confirmed it is a windsor spread bore, pm me if interested.

I was thinking Holley or Weiand did, but like most they only use a Spread/Square Bore combination. Although known to have better MPG the spreadbores were often noticed to engage the secondaries too early. Squarebores evolved to solve some of that problem and give more throttle area before secondaries dumping. Now morphing into both to give the full advantages of both.

I have the offy with the spreadbore pattern on it. You have to machine it out to fit the secondaries of the q-jet. I can text you a pic if you need since I haven't been able to get pics on here.
