Hi, my name is Lucas, I have a 79 292 y-block, which i'm considering to do some working, and adding more horsepower. Here's what i think:

-Increase the compression ratio, from 7,8:1 to 9 or maybe 10:1.

-Holley 4 barrel 600cfm (I'm using a 2barrel 350cfm).

-Work on cylinder heads, valves, etc

-Eletric fan

I already use electronic ignition, with high power coil, but feel the lack of power on my engine, seems like this engine gives like 100hp at most...

Well, but my doubt is about the cam, I took a look on summit racing, and there is too many options for a y-block noob, so I figured to get some tips here...

What's your goal with the engine? Will it be a race car or street car? Do you want a lopey idle or a smooth idle? Are you running an automatic or manual transmission? Does fuel economy matter?

I suggest you talk to John Mummert. On the links tab he has a web site with alot of performance parts listed. But it would be best to talk to him and explain what you want. Great guy and always willing to share information.

It is a street car, but i want as mutch horsepower as I can get (with a stock engine). I want a middle term about idle and fuel economy, It's more like a weekend pickup, but sometimes I use it during the week, but horsepower is wat I  want!

Ok, thanks for the tip, I'll send-him a e-mail.

*Assuming that this engine has now 120hp for example, I wonder if, with this preparation, I can extract a least some 50 extras hp??

F100 1979 ~ Y-Block 292

Absolutely. Recent dyno testing and past experiences of others indicate that about 280hp is possible without any exotic work.



So is that engine stock for the '79 F100 where you are?


Lawrenceville, GA

Really!? 280hp, with this kind of work?! Nice...

Yes, that engine is stock for the 79' F100, here is the Brazilian F100 Y-block (272cid) catalogue:

i put one in a 78 and its a drop in.

Sorry, didn't understand what you said...

F100 1979 ~ Y-Block 292

I think he meant to say that he put a Y-Block in a ’78 Ford pickup and the Y dropped right in.  At least that’s how I interpret it.  Ford quit putting Y’s in the U.S. built trucks in 1964.

Ok, now I get it... Thanks!
