Hi need some advice for choosing a good Cam & Heads for my 292 (from a 55 F100), I'm using it for the strreet so don't need anything too wild, the engine i have came from a friends F100 and was running like a watch. Havn't pulled the engine apart yet but wanted to scource parts first. the car will have a C4 auto in it.

Opinions ???

 

Cheers

A cam rated at 224 @ .050 with a rated duration of 270 with a 110 degrees

a little hotter cam would up the degree @ .050 to 235 and keep the rated or running the same(270 degrees)

These cams are very streetable and are much better than stock.

The 113 head is my favorite,the G posted would be my second choice.>GB

That's pretty much along the lines i was thinking Gary, Could you suggest any good suppliers ???

Is the 113 Head a stock Ford item ???

Hi; Can you give some more info about your ride. Car, truck heavy or lite ? What is the final drive ratio ( rear end gear ) ? Try to get as close to a true 9.0 to 1 compression ratio as you can. With an automatic, manifold vacume at idle in drive is a factor. If you idle at 1000 RPM it will creep. If you only produce 13 inches of manifold vacume at idle it will be a slug. Consider keeping your 55 heads and going with 57 intake valves. Try it as is with a four barrel and dual exhaust then go from there. Let us know what you decide and how it works. Pete

I know posted heads are supposed to be best, but Mummert says he often finds cracks in them around the center exhausts. I have a very fresh set of early "G" heads I was going to build for a little C/R boost over my 113's. Would they be alright I wonder for a stock motor that wouldn't get flogged too hard?

Before you buy a lot of parts, first determine what engine you have.  If you have an original engine from a '55 F100, it should be a 239.  This is not to say someone didn't install a 292 which you later received, it's a bolt-in swap.  There would be no need to put big valves in a 239, and the compression would be very low with G or 113 heads.  Yes, the 113s are factory heads, the complete casting number is 5752113.

If you really do have a 292 and not a smaller engine, the non posted G heads would be perfect. You need as much compression as you can get, and the G's help plus have the big valves. When you assemble the engine make sure you have close to a 0 deck height. With a .040 head gasket and 0 deck you will be close to 9:1 compression

Thanks for that John, Will check numbers and let you know.

It came from a good friend but i guess anyone can make a mistake.

John checked engine number today and your right its a 239, Number is EBU, Should have checked instead of trusting someone i guess. I may as well use it as i have got it now, Any advice in pepping it up would be appreciated.

Cheers

EBU was '54 passenger car, EBV '55 truck.  If you have an EBU, there some  things to consider.  First, pistons are very hard to find.  Second, this is the only Y that used larger cam journals and a 13 tooth distributor gear, so aftermarket cams are in the same boat as pistons.  The original distributor was vacuum advance only, but can be changed to later style.  Also, I hear that later heads have some differences in water passages, so are not a bolt on as such.  Ford once offered a special head gasket to put later heads on '54s, so I would assume that by studying the heads, blocks, and gaskets, you could probably make them work.  All is not lost.  If you bore the block 1/8", you can make it a 256.  256 pistons are probably hard to find also, but 272 pistons will work.  You could also use a 272/292 crank and make it a 272.  A cam grinder could probably regrind your original cam to a better performance grind, but an all-out race grind could probably not be done.  If you decide to stick with that block, let me know and we'll map out a plan.  Personally, I think you would be happier with a 292, it can be bored to 302, and better heads and cams are available.  Speed costs money, how fast can you afford to go?
