Sorry, I think I gave you the weight of the SBB manifold. Let's see if a BBB manifold is mentioned... Devon
67 lbs according to https://www.v8buick.com/index.php?threads/weight-of-a-1970-buick-455-intake-manifold.26609/ Devon
SPX = 25 lbs according to https://www.v8buick.com/index.php?threads/all-up-weight-for-those-that-might-be-interested.354063/ I bet SP1 is very similar, have worked with both. Devon
I wish someone would make an aluminum exact (or close) replica of stock Buick 455 intake like Olds W-30 had......I bet 18lbs
Just imagine if I 3D printed a carbon fiber/Polycarbonate intake like the LS platforms. And valve covers and air cleaner assembly....
Confoozled: we've got 67 lbs on one end, and 49 on a scale. And here I had (from somewhere); 72 lbs for a bare intake.
Not sure what to tell you. The 455 also put out 510lbs but no evidence has been provided that I am aware. Edit, my scale is off maybe +/- 1lbs as compared to two others.
