Getting the Intake on Intake Manifolds
Edelbrock #LD-4B
Can the LD-4B work well on the 340 or 360.
Absolutely, and {untouched} it is a better Intake on the 340 or 360 than the Edelbrock Performer #2176.
#LD-4B > Port Dimensions ............ 1.05" x 1.95"
With a little grinding {Gasket/Port Matching}, these units are an excellent performer on the Street with
a 340 or 360, especially in Low-End Torque and Mid-Range Horsepower.
* 340/360 Gasket Size ..... 1.16" x 2.27"
* 273/318 Gasket Size...... 1.05" x 2.07"
Note; Back-in-the-Day, we developed a 'tapered' Intake Manifold Gasket for Mopar, to provide for a
better {aligned} seal when using an #LD-4B with 340 Cylinder Heads so you wouldn't have to grind
out any material.
We still have the formed template plate, which is 1/16" {0.65"} in thickness.
