Looking for opinions on Mopar M1 single plane intake

Fast340 I wasn't trying to slight you in any way, just usually see the bigger intakes on more max effort or larger engines.

The Weiand is a good intake, proven by the numbers Don posted. I ran a Victor 340 on my 408 because I got a good deal on it. My Dart is a street/strip deal and the engines are always built to run on pump 93. With the 408, 3260# and 4.10 gears it ran 6.53 in the 1/8. Now it has a 434 with Indy heads, intake, solid roller, around 3350# and has ran 6.40 and will run deep in the .30's.

No worries. Sounds like you have a killer combo!
