Got a 351m, been looking at intakes, looks like i really only have 2 choices the
Edelbrock Performer Intake, or the Weiand Action+Plus Intake, already got the 4 barrel just need the intake, anyone out there put one of these intakes on there 351m/400? or another kind of intake, which one would be the best to get and why. Thanks!

 

My brothers ar both running Edelbrocks that came with their pickups. They have a thin mounting surface for the carb. I have heard that sometimes cause problems with vacuum leaks. When I rebuild mine I am looking at the Weiand because of the wider mounting surface. As I understand it, performance wise they are about a wash.

 

Holley carb? Weiand intake.

Edelbrock carb? Edelbrock intake.

But even before a 4v carb is a dual exhaust system and headers.

 

I have been running a Performer with a 600 Holley on my 400 in the Ranchero for years. It's a good all around intake. I've never had a problem with it. I scored a single plane for it recently as I'm going with Aussie heads and more compression from that.

 

I currently have both on different trucks. Both work well. Edelbrock still made in USA i believe. Weiand used to be. Not sure now.

 

I just put the EDEL 2171 intake on my 351M with the 1405 carb on it. It started right up, idles and drives a lot better than the 2bbl carb and intake. The whole swap took me about 4 hours with a run to the parts store the next town over, and food. I've been driving with that old 2bbl since I got the truck in 2010. I couldn't be happier. Throttle response is much better, it doesn't die at idle with the brake pedal depressed and fires up much easier. a note that my old carb was very very worn. If anyone wants the old 2bbl shoot me a PM, I have no need for it.

 

I bought and installed a Edelbrock Performer intake and Holley 600 list 1850 carb on my '77 351M back in the '80s. I pulled the Holley and installed a Edelbrock 600 cfm #1405 maybe 3 years ago, no more leaky FB joints, no bad accelerator pump diaphragms, no more blown power valves. Minor tuning and a Holley FPR and the Edelbrock carb has been flawless.

The intake has never given a problem, never leaked. That "thin" area for gasket sinks deeper into a gasket at same torque loading on them bolts because less surface area. I use wheel bearing grease smeared on my carb flange gaskets.

 

The Weiand Action+Plus Intake is a better all around intake. Run a 1" 4 hole spacer under it.
