Edelbrock Upper W/ Truck Lower??
 

Can I use an Edelbrock upper with a truck lower? If so how does the truck lower compare to a ported edelbrock lower? Thanks in advance!

Nope. A truck lower can only be used with a Holley Upper or Saleen upper.

Also the Edelbrocks can only be used with Edelbrock setups (uppers and lowers must match) because they have rectangular ports..
I don't know how a ported truck or Edel would stack up against each other though. They can both flow some pretty good numbers when ported.
