Y-block ‘B’ intake manifold question
Recently picked up a manifold to change out the stock 2v intake on my ‘56 truck to a 4v. Plan is to have it hot tanked first. While it’s at the machine shop, should I have them deck the carb mounting surface? Outer perimeter looks ok. It’s the center section that has me wondering. Pics below. Thoughts?

Are the intake manifold surfaces that mate to the heads in similar condition? . Last edited by dmsfrr; 11-07-2021 at 09:02 PM. |

The '57 B intake will have slightly larger ports than the '56 heads, but will still work.

Yeah, that’s right. Just a stock 272 .040 over. Adding ram horn manifolds to get rid of the crossover pipe. Also adding a ‘57 up distributor. Should help wake it up a little bit.

IMO The mounting pad needs to be surfaced. If you do the inner pad you also have to do the outer pad or it will not seal. |

That’s what I was thinking. Removed the studs in anticipation of that. Thanks

That will make a nice combination my buddy did it to his 56 F-100 with a 292, he is using a 500 cfm Edelbrock carb. runs great.

If your '56 truck has its original Loadomatic distributor don't forget to replace it with a '57+ version. . Last edited by dmsfrr; 11-08-2021 at 04:18 PM. Reason: another photo |

Re: Y-block ‘B’ intake manifold question
Yblock57, your machine shop should be able to tell you whether or not the intake manifold needs to be surface. Gasket choice/sealant could make a difference.
Have you selected a carburetor? Although I have a Holley 4150 Street Avenger 570 for my .060 over 292, the Summit 500 and 600 cfm carburetors have gotten good reviews and are cheaper. You can also go to Holley's site and see what they have in factory refurbished carburetors in stock. You might be able to save some money, if they have what you're looking for. |

Re: Y-block ‘B’ intake manifold question
I have a Summit street/strip carb on my streetrod, and it is a nice trouble free piece. I did some tuning on it, and now I never touch it.

Yes sir, you are correct. Picked up a ‘57 + strib with the intake as a package deal. In the process of cleaning it up Weights are sticky and everything needed a good cleaning & lube.

I do not have a carburetor yet and was planning on asking here as part of the research. Thanks for the recommendations. I’d like to keep the manual choke knob on the dash functional. Can the new carburetors be converted to manual or do they have to be built that way from new? That also brings up the choke tube in the intake manifold… should I just plug each end with a cap or screw?

Re: Y-block ‘B’ intake manifold question
This isn’t directly applicable to your engine, but here’s a link to Ted Eaton’s carb test on one of his engines.
https://www.eatonbalancing.com/2012/...ting-on-the-y/ There’s also been some discussion on the autolite and new summit carbs over at yblocksforever that you might find interesting. Pretty good looking engine compartment, and about to look better. How about a picture of the whole truck? |

Re: Y-block ‘B’ intake manifold question
Yblock57, that distributor looks pretty rough. Don't you think that nice truck deserves something better?
Ted Eaton recently tested a CRT Performance electronic distributor for Y-blocks. Although they're made in China, he could not fault it. It has a mechanical tach drive for 55-57 Tbirds, but also provisions for hooking up an electric tach. It also has an adjustable vacuum advance. Expect to pay about $250/w free shipping. They may have one without the mechanical tach drive that's even cheaper. Lots of good stuff can be found at y-blocksforever.com, and Ted is very good about replying to email. |
