I have had this on going 302 project. I go t the motor in and then pulled it agin to finish work on the engine. In the process I had some peaces stollen. I am slowly getting them back now. I found a cool shop in the industrial area of long beach that might be usefull for all of us. I got a timming cover and harmonic balancer for a pre 80's 302 for 15$ a peace. In addition I got all th bolts for both parts and three main cap bolts to boot. This place dismanteles old engine that junk yards don't want and clean them up to sell back to rebuild shops. I even could of gotten a oil pan for 10$, but forgot which kind I would need. heads were 30$ a pair, would certainly need a rebuild, but still...

Which brings me to my next two questions. would a pair of 351w head be a good bolt up for more power to my project engine. my 302heads have had a full rebuild to stook. I though that a 351w heads might work and could give me 30-40 more ponies. Someone told me that they woould work. Is there anything I should know, before thying this. Will it drasticly effect my commpression ratio. ...? I plan to go back within 10days or so. Would any of you/ us like me to get some prices too.?

I hope you guys can help me with some of my questions!

Will a car 302 oil pan work. one form the late 70's maybe. its for a 2wd f-100

 

 

I posted about an article written by Jack Roush that talks about building up 289's and 302's. His suggestion for heads was 351W. He wrote that the 351W heads would bolt right on if you also use the 351W intake. I'll email the article to you when I get it scanned.

 

can you post or pass on the address and phone # of the place you found in long beach Please!! or e-mail to me... iam looking for a harmonic balancer for a FE390

I went to the ecology auto yard in longbeach/ off of PCH Pacific coast hiway. They have the bal. you need or any for that matter of 17.99$ pluss tax. That dam yard had for fe-blocks than I knew what to do with. It was of no help to me.
I s there a signifigant diff from a 352/360/390/428 bal. are they the same. I don't mind pulling one for you and then sending it. The other place I didn't even get a reciet. When I go back for the oil pan and bolts I will get the name and phone number and post it. The junk yard off of PCH had at least 10 FE's still in 70's trucks. Write me and justin62379@cs.com if you want to make arangements for me to get it for though. No real trouble.

67 f-100 240/ soon to become a real nice 302.

 

-I took a 302 out of a 67 Ranchero, and the oil pan worked in my 76 F100 fine.
-Don't use a FE balancer, 360/390's are neutral balanced and aren't counterweighted properly for your 302
-Be careful about using 351W heads. There were many differences and changes in Windsor 302 & 351 head designs thoughout the late 60's and 70's. In the 80's they are the same casting except for some bolt hole size differences between 302-351. You need to know what you'll end up with for a compression ratio. Some combinations could yeild either too high, or too low compression. There are also differences in waterjacket openings. I have HP books: How to Rebuild Smallblock Ford engines by Tom Monroe. It goes into much specific detail about this up to about 1980.
- Make Sure you know how your 302 crank is balanced, around 1981 302's changed their counterweight balance significantly.
- You can use 351 cams or 302 cams but they have different firing orders so make sure you wire the firing order the same as the kind of cam you have. (my 302 had a 351 cam in it and until I found out about this, it ran very badly 'cause half the cylinders were firing at the wrong time)

I was talking about the 390/352/360 balancer for some who might need it. I got my 302 bal for 15$ I found a place where I can get lots and lots of fe parts, but it had very few 302's. Thanks for the info on the 302 with 351 heads. Do you know if I will need to run a 351W cam if I use a 302 block with 351w heads and 351w intake. I have my 302 done, almost. I am trying to determin the engine spific parts right now. like the year and stuff, maybe even the year and stlye of the heads. I want to look but will need to get new valve cover gaskets; agin. I gues I will.


bye for now.

you can use either cam, just use the same firing order that the cam is for. The cam grind to achieve what you want with the components you have is what matters, just know which firing order it uses.

Thank You BBT. Can you tell though if a 390 uses the same balancer as a 352 or 360????


Questions questions qeustions...

67 f100 240il6 hoping to get the 302 up agin.

 

352,360,390 use the same balance. There are some variations in the damper depending on what the pulley arrangement is. I am keeping my eye out for a multible pulley balancer. Mine is a single belt balancer all in one. I got a multible pulley that bolts to the balancer, but that pulley won't nest with my balancer and the bolt holes don't line up. I have a FE power steering pump so if I get multible pulleys, and a power steering gear, and power steering column I can convert. The 428 and the 410 (a Mercury that used the 428 crank in a 390 block) have external balancing so they differ from the other FE's and can't use the same balancer.

Look for 69-70 351w heads, bigger valves and smaller combustion chambers. You will need the 302 intake man. because of the 302s shorter deck height. I think the gasket has to be modified to open up some water jackets. Also, the 302 block has to be drilled and tapped for 1/2" head bolts. They used to make a shouldered 7/16" head bold for this swap, but I dont know if they are available any more. I would just modify the block for the 1/2" bolts. Either cam will work I the firing order is matched to the cam. 5.0HO motors run 351 cams from the factory, thats why they have the 351 firing order. Your 302 with early 351 windsor heads should scream.

Man, I'm learning alot of good stuff here!

Can sombody tell me the firing order on this extra cam I got with my 351W?

The box says Ford Motorsport
M-6250-E303 for 302 CID HO

The end of the cam is stamped
494370
m 6250 E303

you guys are great-Ed B

I don't know if this is the person or the right place but I just read an article from Carcraft that says with nothing more than their Air Flow Research 165cc Smog Legal heads on their small block Ford took the best bolt on performance gain they ever saw. They changed the heads, headers, and rocker arms and gained 100 Hp. Yes 10 x10 horsepower. It was on a 1991 Ford Mustang. which had Forged aluminum pistons, and hydraulic roller camshaft stock. I was wondering if these would fit on my 1981 302 Windsor in my 1981 F100? I guess I will call Air Flow Research and ask them. Says it is an easy bolt on. So now i am doing my research.

 

Using 351W heads on a 302 is too general a question. Depends on what year 351W and which pistons the 302 has. Heads and compression ratios dropped in the 70's thanks to government emission standards. Example: 1976 351W heads you'd loose compression ratio and power.
A car pan would carry one quart less fluid. Plus, you have to match pan,oil pump pick-up,dipstick, and tube. You would have to make sure your 302 has a hole in it to support whichever dipstick tube the pan of choice requires.
