Mercury 410 Fe ?
I wanted to know more about this engine . I think Denny runs one . I did know a guy that had a 66 Mercury with a 410 . Is this a 390FE with a 428 crank ? Was it only used in Mercurys . In one book its listed at 330HP 444 ft.lbs torque . Did it use good rods and a forged crank ? I use to work on 391FE 4BBL truck engines . Man that intake was like 100lbs .

Yep 390 4.05 bore with a 3.98 428 crank. 66-67 Mercs had them. Used std forged FE rods and the 428 cranks are nodular iron not forged steel. It's rumored some pickups came with them as an unknown option. I've never seen one personally. The 410 pistons were used in the pickup 390's tho. With a higher wrist pin location this was a solution to getting a low compression truck engine without new piston tooling. Denny is the resident 410 expert. I'm sure he'll tell ya more!
The 391 Ford truck engine . Is that a 390FE . One of the 391s that I changed out had a 352cast in the front of the block . At the time I had a boss that ran a 406FE and he said that was on his block also . The engine that I was installing in the truck . Had paper work that said it was bored 60 over and the crank was 020/020 . That engine also had a 600 Holley from the factory . It had the cool valve covers that said powered by ford . And for a big F600 it was fast .

DENNY did the 422 in your hot rod start out as a 410 ?
Yes it did. They put the 410 in Mercury's. 66-67. Stock 330 hp. Mine is .060 over. 60 thousands over for the ones that don't know.
It has 575 hp at the wheels. Now, it will have 625 when I'm done.
Originally, with the 575 at the wheels, I had a 780 Holley carb installed, and timing retarded 10º. The following weekend when tested on a dyno, I installed a 850 Holley, and set the timing where it should be, and pulled 630 at the wheels. No, I don't have the proof, that was long ago, and so is the spec sheet. I run it retarded 10º from what I'm supposed to run it at, and use the 780 on the street. 15 mpg, and plenty of get up and go like that. I won't need any more than that with this 34 Chevy truck anyway.
I think the 410 was also in some Edsels and Mercury Marrauders in 58-60.
No, not the 410. Well yes, but not the same as he is talking about I believe. The bore was different to stroke ratio back then.

Denny W What heads do you run on that 422 ? And what size are the valves ? Are they ported out ? Have you ever ran that 34 Chevy at the track . Do you run a Ford C6 and 9in rear end in your 34 ? Real COOL set up I like it .
391 was a FT engine. But based on the 390 4.05 bore block. It used a 3.794 stroke forged steel crank with a larger snout dia than the std FE cranks. Heads had big chambers with small valves with the heat crossover in the center not offset like the FE's. I've only seen a few different foundry identifiers. 352 and the reverse 105. All of the old 406's I had did not have the 352 on the upper left part of the block. They had "HP" on the side and rear of the block. And by the cam and crank saddles on the inside. I have seen a few builders that stamped the CID on the outside of the block. But nothing like that from the factory that I've seen cast in. And I sure have not seen it all some 30 years later. New things pop up all the time on these old engines.
That is what the # was 352 . It was on the front of the block . I was thinking 361 because we had some 361 Ford engines with 2BBLs . Do guy build the 391s for racing ? And can you use the FE heads on the 391 . Thanks for the info .
Lots of work on the stock heads. Back then, I ran a close ratio 4 speed, with a 3:91.1 posi rear, in a 69 Ranchero, which had a 351 w engine, automatic then.Originally Posted by tango
Now, in this truck, which is still going together, I'm going to be running a Built C6 trans, and the same 9" ford rearend. The 69 Ranchero, with me in it weighed 3900 lbs. This 34 truck should only be 28-2900 lbs when finished.

I Like the C6 trans . But we had two at work on E350s that the tail housing cracked by the mounting area . And I check the engine mounts they were ok . I think you can buy a cast iron on that was used on some big block Mustangs and F600 trucks . But the C6 is a real good trans .
The weight of this truck, compared to the F350, is no problem in cracking the tail shaft housing. But, the tires will take a beating, or should I say a burning ?
See if you can find one of the cast iron C6 tails . That Mustang 67 guy might know were you can get one .Originally Posted by DennyW
I'm running a tail shaft vibration support on there. Never had any problem with this. It's really hard to find parts around here anymore.
