does anyone know were i can get a set of flat top 351m pistons?...iam having no luck finding some...thanks in advance

 

How close are Sterling/Federal Mogul part # STL-451P30 (30 over) to your needs?
3.50 stroke , 6.580 rods , .088 inch dish
About $9 each.

 

havent checked them out but i will i apreciate the info hawk

 

The only mass-produced 351M flat-top piston I've ever seen is the SpeedPro (TRW) #L2466F, and it is available in 0.030" oversize only.

Advertised CR: 10.83:1 (58.6cc heads), 10.43:1 (63cc heads), 9.84:1 (67cc heads), 8.96:1 (76.2cc heads), 8.78:1 (78.4cc heads).

 

Summit no longer carries the TWR L2466F.
Maybe JEGS ???


Keep your stick on the ice

 

does anyone know of a web site for TRW pistons??

 

I think TRW Pistons are made by Speed Pro.
They must be owned yet another company. I can't find anything on the web about a manufacturers site and none of the part sellers have a link to Speed Pro or TRW.
I'll do a bit more digging and see if I can find who owns them , but I don't think they will have anything usefull about pistons on the net.
Summit has the best list so far.

i appreciat the help brian!

 

well after going over the sites you listed brian so far i have found some flat top 351m pistons on the rossracing page only problem is they are 586.24 for the set that kind of takes a chunk out of my ***. but hey high performance isnt cheap right.?.

 

I looked at the Ross pistons and they were listed under custom forged pistons with a vague description like "Ford 302, 351, 400 Cleveland & ""M"""
Flat Top 19-10 $586.24

There was only 1 part number listed so I'm guessing it means for 302C, 351C and 400M. They probably don't know Fords well enough to know that 400M is not the correct term, and they also use a larger .975" pin.
Most of these custom pistons are made from Chevy blanks and use a .927 Chevy diameter pin.

The 351M piston has an unusually tall CH of 1.947" This is the tallest, heaviest, 4" piston Ford ever made and I'd be surprised if there was a Chevy blank available for a custom forged piston.

This is also one of the reasons why a 351M does not like to rev high. The heavier the piston, the more load it places on the rods and crank.

The other reason is the crank. Even though the 400 was based on the 351C, the crankshaft is 13 lbs heavier. The longer stroke, larger diameter main journals and the massive counterweights makes it weigh almost as much as a 460 crank.

Since the 351M came out 4 years after the 400 was designed, Ford took a couple short cuts. They just destroked the heavy 400 crank, and instead of making longer rods they made taller pistons. For a low speed, heavy duty application it worked fine, but for a high revving big horsepower engine it's not a good idea.

The internals need to go on a diet. A 351W crank may be a possibility. If so, there are a lot options. I'll see if I can find a combo that can use some off the shelf pistons.

 

i really appreciate the help brian this engine build up is becomming a pain in the ***.....but thanks man!

 

What kind of budget do we have? Application? Will this be a complete rebuild?
I have a couple 427ci combos and one 383 I just came up with.

 

well budget wise is going to be anywere from 2000 to 3500 not a complete rebuild just a top end rebuild basically i have a brand new motor that is bone stock so i am wanting to squeez as much out of it i can. the application will be some road mostly offroad its just going to be a toy.

 

Where can I find 400 pistons
