To a degree, you can get better performance, and fuel efficiency. I find that the weight of the foot has the greatest effect on efficiency.

The most recent build of my engine gets about 1mpg better on the highway than the old one and it is a lot more powerful! Unfortunately I never checked mileage with the stock 292 that was in the truck when I got it. Don't know how it compares there.

With the cam he's planning to use, more efficiency and power should be possible.

Efficiency went out the window when you put a cam in for more ponies.  Scavanging, by design, pulls raw intake into the exhaust, just to make sure your combustion chamber is purged of exhaust gasses for the intake stroke.

Ford 292 Y-Block major overhaul by simplyconnected

I don't remember if I'm getting any head work done, I think it's just a rebuild, but I'll check anyways..

I shouldn't be lookin for HP anyways.. I shoulda asked about EFFICIENCY... LOL

I downloaded a trial version of a desktop dyno program. After some tweaking of numbers, I came up with 250 HP for a 312 with a stock 57 cam, ported cylinder heads, and headers. You might try it, too.

Well since no one around the website has real good #'s except for MUSMMERT's #s on his strokers..it's only $30 for 3 pulls near me at a newer dyno place.. So after I get the thing tuned how I like it after I install it, i'll just have to bring it down and get ya'll some #'s :-D.. That's of course after I break it in 1k miles or so :-)

Ballpark horsepower numbers would be the same with similar components on a scrub, mopar, or newer Ford. If you've got about 300 cubic inches and the heads flow ok, then it's the cam that determines horsepower. A 212 degree cam on a scrub 305 will make the same power on a 299 y-block.



Stock Ford y-block 113/ECZ-G heads flow as much or more than stock C5AE 289 hi-po heads. Ported y-block heads flow the same as ported 289/302 heads. You have to buy purpose-designed cylinder heads to out-flow a y-block. So any differences in power would come from the subtle differences in engine design. For example, y-blocks have stiffer lower ends, taller decks and longer rods, and shaft rockers. They can be spun to higher RPMs than a Windsor because of the stiffness, and they endure superchargers better. Of course, higher flowing y-block cylinder heads are being designed right now, and that will put the y-block back in the horsepower hunt.



But, getting back to your question, you can probably find someone with a desktop dyno who can give you a good ballpark estimate of the power.

sorry I didn't see the IDK and QNA.. And I wasn't taking offense. Just like I hope you guys take offense with silly QNAs like this..lol... I mean I know in my mopar, or in any other small block, goin .30 over with a cam, refreshed heads and a decent intake and W/E usually is around 300hp. I understand it's hard to get HP outta these bad boys. I need to get it stuck in my head that this is my daily driver and cruiser.



QNA= Question and Answer

IDK= I Don't Know

W/E= Whatever

Apache,

Don't take offense, but IDK and QNA is a little tough for us old folks.  I got the LOL!  I didn't get the BC or the first two mentioned.  It is never too late for us old dogs to learn a few new tricks, but you know, when in Rome...........(or are you too young for that, lol).  Keep up the enthusiasm, it is refreshing and gives some of us older Y-Blockers a jump start.

later dude...................

Was that directed towards me? I thought for the most part all of the shorthands I wrote would be understood, sorry...



CFM= "Cubic Feet per Minute". This is a measurement of air volume velocity and is often used in measuring air flow from heating or cooling diffusers.



BC= Because



HP= Horsepower



TQ= Torque



AOD= Ford's Automatic/Overdrive Transmission



I think that was all the shorthand I used, but i'm not sure...sorry....
