ok, I am looking to put a ford engine together. Here's the rules:

Stock stroke for block
stock cast iron heads
hydraulic flat tappet cam
360 max cid
9:1 compression
cast iron intake and exhaust
factory 4 barrel or holley 4412

Can someone help me put something together that will compete with the chevy's?

Ok John, I'll do a little pecking for ya.

You can use a 351 cleaveland with mods for bottom end oiling. These have great heads in the 2 bbl form and go with the 4412. The valve sizes are 2.05/1.72 if not mistaken. As said previously you will need to work on the lower end oiling. This motor is also very heavy and bulky.

The next option is to use the 351 windsor. This is a great little motor that is fairly light. For heads I would see if I could get away with the GT40's, they came stock on 302 (5.0L) explorers, I guess it just depends on your tracks "stock" definition. If they wouldn't allow those hunt for 69-70 351 W castings. These are gonna be pricey, probablymore than a good set of aftermarkets. Cams are plentiful, the 302 cam will work with a change of firing order if you can't find the right grind for you. You will be able to find a 4 bbl intake on 80-86 trucks with the 5.8 HO motor. No good exhaust manifolds exist that I know of, just hog em out. You can use the duraspark electronic ign., its real easy to hook up, just 2 wires and its dependable.

Most of your tech men aren't gonna know whats what cause all they deal with are chevys.

I know, the rules state stock stroke, but i would seriously look at either the 331 or 347 (stroked 302), or something as big as a 393 (stroked 351). The track you are going to be running at (Lakeside I belive) is full of 350's and i am sure 383's. The advantage of a 302 stroked or not, is that you will loose about 50 lbs compared to the chevy guys. If you would like some more info let me know, we are putting together a ford for racing in that area, and have found quite a few resorces and what not that may help.

The GT40P heads flow great, have a smsll chamber and were installed on stock on explorers. They are also quite affordable. Should make a killer 351W. I am not sure about the stock 351W intake, though. Exhaust manifolds from a late 90's explorer will fit the heads better

I almost forgot. The most important detail to remember when building a Ford is to check your piston deck height. Ford added .027 to the deck height for a few years in the mid 70s. Most replacement pistons are designed for the lower deck. Combine this with production tolerances and all of the sudden you have .045 deck clearance. Add this too a .042 head gasket and you have .097 piston to head clearance. you will be giving up 1 point of compression as well as the benifits of having the piston and head coming close to each other.

If they don't check to see if the stroke is right I,d go with the 347 there is plenty of 302 blocks around.I run a 347 and it kicks a$$.Its on its 3rd year with 0 motor problems and it is about 50 lbs. less than sbc and about 90 less than a 351w.You can find some fair priced stroker kits.I run flat tops with windsor jr. heads milled to 54cc chambers which puts it just shy of 12 to 1 I turn 7000 rpms and it loves the big 1/2 mile track I run on

What kind of rpms would a 9:1 351 with stock heads want to turn with cast iron intake and exhaust. Anyone have any suggestions on a good ford circle track cam? Thanks.

there are several solid lift cams for fords marketed by speedway that are good. use the smallest one......don't over cam it. 6500 rpm's and you're done with a stock intake.

The 'Clevor' would be the best thing if you have the patience (and $$$) to make it all fit. I think the intake is the hardest thing although there are plenty of adapters out now. http://www.pricemotorsport.com/Intake_Adapters/AP-16/ap-16.html
The Cleveland style heads (351M/400 heads would work too) flow a ton more than stock Windsor heads. Even lame 351M heads have 2.05"/1.65" valves and much bigger ports than a 351W has. Although getting compression up is kinda tough, but you're limited to 9:1 anyway, so that shouldn't be an issue either.

Get a cam with around 240-250@.050", 108 LDA w/104 intake CL and .500"-.550" lift. If using the Cleveland style heads, a single pattern would probably be best, if using stock Windsor type heads, a dual pattern with a slight exhaust bias would help the weak exhaust ports. With all the restrictions of the stock manifolds and low compression going too big with the cam will make it lame off the turns, so you'd have to gear it higher, then you'll hit the limits of the stock intake and exhaust, so then it's lame at the end of the straight... etc etc. It's a vicious loop that really needs some trial and error testing with your particular car/track/motor.
