Gmc v6 4 barrel intake.
Some of you might not be on Facebook “big block gmc v6” group but over the last year or so I’ve been developing a 4 barrel intake manifold to fit these and have been seeking a company to make them.
Today I found a company who is willing and they got me a quote! It can be made to happen if we get 10 people at 550 each. The file size for pictures on here is tiny so I’m going to reference my Instagram so that you can see it. I’ve 3d printed a prototype (1pc) and am going to be checking my dimensions so I can submit the final revision of my drawing. Reach out if you have any interest in this or any questions. https://www.instagram.com/p/CR1lXMbHKXt/?utm_medium=copy_link Posted via Mobile Device |

Re: Gmc v6 4 barrel intake.
I don't need one, as I don't have a V-6, but that is one cool piece! Looks like a tunnel-ram. Hopefully you find enough takers.

Re: Gmc v6 4 barrel intake.
I thought the same thing initially but I don't think that is much more than a performer RPM hieght wise. If the runners are sized good it should be a nice runner. I wonder if they can get a cam to support that air flow now. A quick look on the net says max HP RPM was only 3600 RPM with around 150 horses. Interesting for sure.

Re: Gmc v6 4 barrel intake.
That would be good one for high RPM not so much for idle and low speed driving.

Re: Gmc v6 4 barrel intake.
Big Block GMC? What's a small block? I thought you had to have a small block to have a big block. Sorry, a pet peeve of mine I guess. I think it's great to see performance parts coming around for these mighty motors. Gotta design off the original dynamics of these low RPM torque monsters. Some got it up top while others got it down low

Re: Gmc v6 4 barrel intake.
Isn't the biggest displacement of that engine something like 470+ cubes? Even if it doesn't wind up tight, more flow would still be beneficial if metered properly.

Considering stock is a single plane it should still be an improvement as well as being aluminum vs iron. There may not be a ton of RPM left on the table but I think if it can improve everything below the max I think it’s a win Also cam wise delta cams will do weld/regrinds for 150 per cam (I have one based off my 478 cam) Posted via Mobile Device |

It was probably chosen because it’s easy to identify that it’s not the Chevy v6 by saying big block. Posted via Mobile Device |

Re: Gmc v6 4 barrel intake.
I actually pulled it off.
Still waiting for it to arrive but initial images look amazing. I had to trim this down to make it even remotely cost effective but it’s 3d printed aluminum. It almost doubled the initial price I was hoping for (albeit our govt ruined a lot of this with inflation anyways so oh well) If he’s willing I might let Richard holdener dyno with this, my can and my spare 305 and see what happens. I would imagine a stock 305 would be the worst to try whereas the 478 I picked up would be much more suited and the turbocharged version better yet.
