I see on Mummerts web site it says a new tunnel ram manifold is now available, But no pics yet?
Anyone know of pics and price??

No price but here are pics of the tunnel ram with the supplied plenum on engines.

that looks like a two piece manifold with a weiand top!
By Joe-JDC - 5 Years Ago
It is.  I got a defective tunnel ram from John M, and cut the plenum off, milled it flat, and fit a 289 Weiand Tunnel Ram top to the Mummert.  I had spacers CNC'd to give me more plenum volume, but have since decided it is not needed, and have removed the spacer.  Hopefully I will be able to get the 375 Y back on the dyno sometime soon, and give it a workout.  It was used on the 2018 EMC entry that placed second in the Vintage Class.  Joe-JDChttp://forums.y-blocksforever.com/uploads/images/2a14b63c-c9de-484a-aac3-2228.jpg

Wonder how it would look with that hanging out the hood of my TBIrd?  BigGrin

Phil.  It would LooK awesome, BUT I doubt that you would much like your 'Bird's low end performance, throttle response, and drive-ability.

Perhaps installing 4.50 something rear end gears and jacking the idle speed up would make it live-able.  Too, a 5 speed transmission with the right 1st gear would help to make it work-able.

Apologies for being a wet blanket about this particular thought.  THANKS for all the constructive input you've generated on the Y-Blocks Forever Forum this year! 

Happy New Year!

It was meant as a joke.  I think funny thoughts.  Actually, I ran a tunnel ram on the street years ago.  It had two out of the box Holley 600s.  It didn't drive all that bad,  I enjoyed seeing little kids point at the carbs when they pulled up to a light and the smile on the faces of the drivers.  Old hot rods are cool. 

I'm into Y-Blocks because they bring back memories, most of them good.   If I had a time machine, I would go back to 1965 with the money I have now. I would march right down to my local Shelby dealer and buy a 1965 GT350 and a 7 liter Cobra.  I could probably buy a supercharged 1957 Fairlane for $1,500?  I would buy my high school buddy's 1957 Custom with the straight front axle and my best friend's 1961 Starliner.  I spent my life recreating those cars.
