Oh Nathan...

What is 10 cubic inches? well If I use the measuring scale I've been using on the wife, it would be worth about 200 HP !


Maybe its a 460 instead of a 302...yeah that's right.. a 460.....big...no super block...maybe 600 ci.....maybe 1 gozillion horsepower......'


ok gonna put the pain thinner down.......put it..dow........down....down

"$750 clams to rebuild the y block and still hear the click of the solid lifters?

That 302 is looking better. Maybe I'll run the 292 until she fails while rebuilding the 302."

This thread really has some staying power as you flip-flop every 24 hours. Do you really want to run a 302? Wonderful! Then do it. But if you are doing it because a Y-block rebuild kit is a couple hundred dollars more expensive than a SBF you will be very disappointed. Estimate the cost to convert your transmission, exhaust, crossmembers, mounts, driveshaft, linkages, every damn thing. I can make you a page long list of stuff you will have to replace or modify for a SBF. You will NOT save one dime to convert. It will take 5 times as long.

You just need to decide which drivetrain you want. Leave the cost savings out of the decision because it just isn't there IMO.

 

Hi everybody,

I'm George's (Earl's) son. I just wanted to chime in on the topic. Bob Carlisle (of Bob's F100 parts) did an interesting interview in Rod and Custom Magazine, discussing the performance aspects of the Y Block engine line. The fact that Y Blocks can make serious horsepower (according to Bob...and Carl), coupled with the fact that switching engines (such as to a 302) brings along a host of other headaches, makes the Y Block a good choice, in my mind. Just my $0.02.
Anyway, here's the link to the article:

Thanks for that link Evan!
I think I migh punch my Y to a 300HP girlie motor eating monster!
Waaaaa!!!

Sorry Fenders!

 

Evan

You seem so much wiser than your father. Must be your Barbie Dahl genes. The headaches of changing engine families is well documented here. No doubt Y's can make some power. But if Hands were building for top performance, then the money issues becomes relevant again. It is going to cost some real greenbacks in comparison to a SBF. You can build a true 300-400HP 351 for cheap and it could be built street reliable. I guess it just depends how much power you are chasing with your Y. The availability of modern cylinder heads and fuel systems make it relatively easy to achieve big numbers.

What kind of torque/HP does a 272-292 Y put out stock in '56?

 

I know I probably shouldn't be posting this here, but I sure would want to know the numbers differences between the US y-block and the Brazilian y-block. So, here is a table with all the numbers. It's in Portuguese, but you should be able to understand the values.




Thanks and sorry for bothering you with this.

Ok... I knew I shouldn’t write anything before drinking my coffee… I just realized that I must make some units conversion on that table… Sorry… If I could only find my calculator now…
Sorry. I’ll go have some coffee…

Well, now..having been thoroughly chastised by Mr. Fenders....


I think my grandad said it best..measure twice, cut once. Having new wife, new mortgage, new camper , old truck..old truck is the one that gets last choice of the bucks. I just hate to spend $ down a dark hole and am having a difficult time deciding. 302 cheaper bur more modification problems, 292 more expensive initially but maybe less so in the long run.

This is my first attempt at restoration/modification and the task is monumental when you consider every way you can go. So I appreciate everyones input but in the end the decision is mine.

Please consider this thread closed, dead and buried.

Thanks Lobo!

Can we assume those 302 columns are the SBF we sorta know and love? Or is it a stroked Y ?

Kinda hard to tell.

What fun to burn other fuels too! Rum, Tequila, Pisco, or what? is that other column?

Why NOT Y????

 

Here are the conversions…
For the 272:
33 mkgf -> 238.7 lb./ft
For the 292:
37.2 mkgf -> 269.1 lb./ft
For the 302:
1976:
39.5 mkgf -> 285.7 lb./ft
After 1977:
39.8 mkgf -> 287.9 lb./ft
Alcohol 302:
35.6 mkgf -> 257.5 lb./ft

I just hope I’ve got these numbers converted correctly…
Sorry again…

Midnite Cruiser, the 302 is the SBF indeed. The one on the last column runs on sugar cane alcohol. After late 1975, the SBF took the place of the y-block.

And, in case someone is wondering… The car pictured there is a 1976 Galaxie 500…

The best Y performance was 57 after that it was detuned as Ford was pushing the FE and MEL motors for the high end crowd.

292 212/297 4bbl
312 265/336 dual 4bbl

The 292 was never outfitted as a performance engine by Ford.
These days guys are dynoing 275-280 hp in a very streetable package with no radical machining, etc. Its pretty much just selecting the ECZ factory heads, porting, intake/carb, cam and headers.

Im guesstimating 240-250 out of my .060 over 292 with a cam emphasizing low end performance. Figure on another 50-75 if I ever get around to fooling around with the Eaton 90 blower.
The 312 will be shooting for 280-300 and going into a ~ 2000 lb car.

I agree the 351W is a wiser choice going into a swap if the SBF is the wanted look.

Howsumever a 429/460 with no work done at all will pull stumps and those are being given away. Around here a perfect running 460 with C6 is $300-500.
Some even come with the car still attached, those are often freebies.

You have not been chastised. I am harassing you. There is a difference from this end. Post on O indecisive one. (That was more harassment BTW)

This is a very complicated subject which can't be reduced to a simple equation. You're not hurting anything, I just thought it funny how easy it is too lean you one way or the other.

Carl just threw some more variables at you. There is no cheaper torque than a big block. Unless you start buying aftermarket parts and then they get expensive too.

Here's an equation that might hold some water.

Cool F100 = Expensive

 

I was looking around on Ebay and came across this: http://cgi.ebay.com/ebaymotors/ws/eB...tem=2414671150

A bit pricey but looks to be in excellent condition, Wish I had the money and drive to rebuild my 292(headed for the junk yard as soon as new motor is done along with the stock 4 speed)

Glack

 

But ... but ... but ... you CAN'T just throw away a classic like your 292! Save the whales ... er ... 292's!

 

Yeah, I agree with George. You can’t just throw it away!
Everything I have today, I owe it to the y-blocks…
My headache, my backache, my dirty hands, my empty wallet…
Thanks to them, now I have all those wonderful things.

The y-block is not perfect… But, respecting everybody else’s opinions, I wouldn’t trade a y-block for any other engine…

I have been pondering this kind of decision for a while now and here's my current reasoning.

I have a 351w, a Dodge 360 with a 727, a roller-cam 302 with AOD, and a 312 to choose from. I'm going to use the 312.

My 54 F100 has bellhousing mounts that are right under the firewall. The front engine mount is more of a rest than a mount; it restrains the engine but it doesn't really hold the engine. The bellhousing mounts transfer the torque of the engine to the chassis at a point where it is stiffened by the firewall.

A 302 is usually mounted using side engine mounts attached to the frame. The frame on the front of a stock 50's Ford truck is rather flexible and not designed to take the torque of an engine. Some of the engine's torque will be lost to frame twisting if the engine is mounted there.

My 312 is a 60 over engine that's in decent shape. I have the ECZ-G heads (as well as a pair of ECZ-C heads). I also have the ECZ-B 4bbl intake that takes a Holley/Autolite 4bbl carb, as well as a Offenhauser 3x2 intake and carbs. I'll use a 3sp w/od and a 9" with 3.5 ratio axle.

The whole thing will bolt right in using all stock parts. I'll spend all my time and money just putting together stuff that will be a factory fit.

I recommend using the 292 with a set of ECZ heads (ECZ-B, ECZ-C, or ECZ-G). The 292 for my wife's 55 Vicky was bored .040. by a machinist who usually balks at milling modern heads for compression and overboring modern blocks for displacement. He didn't even ask before he punched that 292 to .040 over and milled her ECZ-B heads .020. He zero decked her block, too. Good stuff.

Try to get the ECZ rockers (1.54/1 ratio compared to the usual 1.43/1 ratio).
