Offy 360 or Edelbrock intake

I currently have my heads at the machine shop, so I am considering options while things are apart. Currently the 455 has an Offy 360 intake and an Edelbrock 800 cfm carb. Is there any advantage to running an Edelbrock over the Offy?

 

The Edelbrock has a better runner design.

 

I ran an offy 360 with a 750 edelbrock carb almost into the 11s I had no issues with that intake......in fact that intake and carb us still in my brother 68 gs 400. Its now painted red and without really looking most ppl never notice its not a factory intake.

I'm sure there is a point where 1 intake is much better than the other.....where that us or how much better I cant answer

 

So, maybe save my $$ for other stuff?

 

When I ran the Offy on a mild build high 13's engine way back when you could actually feel the torque loss of the Offy compared to the stock intake and the car ran faster with the stock intake. The GSCA did dyno runs of the intakes and the Offy didn't do anything until the rpm came up but lost down low. As Ben said his was nearly running 11's and down there loaded with I'm sure decent gear and good converter and probably cammed up to rev well. Is it as good as the Edelbrock in that situation, probably. The question is how fast do you plan on going and what are you going to do to get it there? When you look at the intake it is a single plane unit of sorts with a divider. If it is a mild build get an Edelbrock or put a stock one on there.

 

My car then had 4.10 gears, tci 10" 3000ish stall, foot brake, lunati 33304 cam shifting 5500-5800

 

The Offy is somewhat of a mess when you look at the design. It does have more of a single plane look,but shaped it like a dual-plane. It’s more of an appearance intake. The Edelbrock would give you better overall performance.

 

I met a guy at Maryland International Raceway years ago that welded a Dominator flange onto an Offy and said it worked as well as his TA intake he got to replace it.

 

Did he simply weld it on or did he machine the opening large enough then weld it on?
I’m curious to know what intake he was running before that,and if he was running the dominator with that. It already sounds like he had a salad of carburetor to intake manifold.

 

Was years ago but I remember a 1in or so Dom spacer welded on it....I assume it was opened up underneath the spacer. I thought at the time if I ran across a cheap Offy I would do similar....never did....

 

If your Camed to shift at 5500 max then the Edelbrock will make more average torque in the rpm band where it do the most good!

 

I don't have any real dyno numbers but my butt dyno confirms what you have indicated when I switched these intakes years ago with a C113 cam.
