what do you think of this intake

The best dual plane intakes of yesteryear are the Edelbrock LD-340 & the Weiand Action Plus. I have not personally owned a Weiand. Listening to those that have used them with success in there intended useage parameters gets a vote by myself.

I'll start with Locomotion a and his famous words, "In my application, it worked best."

I have a LD-340 for many years. I did the MP mods to it. If your not building an engine to meet the intakes potential, do not modify it or stay with the OEM 4bbl. Intake which is no slouch.
Modifying the LD-340 raises the bar for that intake. And the RPM range a good bit.
