Just getting some more ideas. 64 tbird (cruiser i accept that fact) 390. Would like a little back seat fun. now if i install 428 crank to 410 it, would i also have to swap out connect rods to allow deck clearance? maybe thinking to much before i get the micrometer out. Like i said back seat fun in a cruiser...maybe swap out some rear end gears also..
I think (but am not certain) that the connecting rods are the same, and the pistons have different compression height to get the proper deck height. It's almost certain that the outfits that sell stroker ***emblies can hook you up with the right combination of parts to get yours together.
Wow, we need to get back to the basics here... Crankshaft stroke determines how far the piston moves up and down in the cylinder. That's 1/2 of the "displacement" calculation. Connecting rod length is determined by stroke, it does not affect it.
The rod length does not effect stroke.You need the pistons with the correct compression height.That is a very popular conversion,I'm sure ****,ROSS and others will have pistons,it was also a factory Mercury option,410 cu.in.. ROY.
thanks for going back to basics exwest..bear with me reading up on to build 390 not ***emble. unfortunately i was brought up ***embling cars and engines as a hobby not to building engines themselves..that is where i was kinda confused on longer stroke (piston up)for deck clearance..no offense animal i am trying to figure it out (not that i wont buy a kit) but to understand. hell i maybe it will help out some other newbss..thanks guys
Probably. Depends on how much more arm length (1/2 stroke) on the 428. You have to make up the difference somehow, and you can only move the wrist pin up so far in the piston. Typically, factory stroke changes used different rods and the same pistons, but either is a solution.
yeah the pin height gets moved up....they are still an off the shelf item but only in limited c/r's... a 410 is a nice torquey motor... thats why they put them in trucks... my dad likes his in his '66 fairlane conv.
Cheap pistons are available, as many later 390 pickup engines used 410 Mercury pistons installed down in the hole for reduced compression- I found a new set of "pickup" +.030 pistons for $40 Rods are the same, just use the 390 rods with good bolts
You can always tell the guys who aren't familiar with the Ford engine families. Ford made 2 different 410 ci engines. The 1st was from the MEL (Mercury-Edsel-Lincoln) engine family. This engine was used in 1958 ONLY Edsels. It was labeled the E-475 (475 was the torque rating). The 2nd 410 was the 1966-'67 Mercury ONLY engine that was part of the FE engine family. It was essentially a 390 with a 428 crank. To the OP: Most everyone else is correct. You will use your original 390 rods, but will have to get new pistons. Of course stock replacement 410 pistons are readily available, but they were a high compression motor, 10.5:1. That may be a bit high if you plan on running non-premium gas. Good Luck.
It not that easy. the 390 is internally balanced and the 428 is externally balanced. Plus you are going from a 3.78 stock to a 3.98 stock which may cause an issue with the piston to head clearance All three engine do use the same length rods. It the wrist pin placement that would cause the issue. Your best bet is to find a set of 410 piston and take every thing to get balanced. (Piston, Crank, Rods, Harmonic balancer and flywheel).
Exactly, I am surprised it took this long for somebody to mention it. You will have to get the entire rotating ***embly balanced. 410's and 428's used different flywheels and harmonic balancers than the other FE's. It is possible to modify a 428 crank so that it is internally balanced, but it takes a bunch of mallory, and that get's expensive. Often the cheaper option is to find a 428 flywheel and harmonic balancer. Good Luck
I just built a 415" FE for my 70's F150 to haul the race car. 390 block, 428 crank, JE Pistons .030" over, 390 type rods, true 410 (or 428) flexplate. This was a real 410 to start with, nice junk yard find from a 66 Merc. so in my case it was easy as it already had all the right bits. JE had forged pistons on the shelf with a 10.5 compression. Cleaned up the heads and a nice high lift short duration cam from Melling and it is a real torquey motor.
The 410/428 cranks do not require a special balancer, just the flexplate/flywheel which has a 28oz. bobweight. FE balancers are all neutral balance, but the 428SCJ used a balancer spacer sleeve with a "hatchet" bobweight built in along with the neutral balancer to compensate for the extra weight of the 427 "LeMans" capscrew rods used in the "Drag Pack" SCJ with 3.91 or 4.30 gears and oil cooler. You can use any of the good replacement balancers, the larger '68 and up style is the best, just need pulleys to match that bolt pattern
Great thread guys. I see most of the parts are listed, but I wonder if anyone would want to throw up a list of parts for taking a 360 or 390 engine to a 410. Also, is that the best way to go? I just bought a 390, already .060 over and want to do what I can beforeI put it in my 67 Galaxie. Hotroddin's is close, but what else is different w/o a 410 block?
Nothing, 410's and 390's used essentially the same blocks, same bore, same deck, same everything. The difference was in the crank, pistons, and flywheel like already mentioned. The 428 block was a different casting to handle the larger bore (same bore as the 406).
This is not getting back to the basics it is just learning the basics to start with. Threads like this are almost as bad as choose my camshaft threads. A little advice to the OP if you want "back seat fun" don't build a hot rod build a custom. Customs are for getting girls and hot rods are for getting rid of them.
Correct, the 390 and 410 used the same block. This conversion is not hard to do. The parts required are: 410/428 Crankshaft 410 Pistons 410/428 Flywheel/flexplate Understanding why only these parts are required is more of a challenge. Piston PIN height or compression distance is the distance from the center of the piston pin to the top of the piston. This distance is the amount of piston, in inches, that is above the center line of the piston pin. If the stroke is lengthened then the piston is pushed higher in the cylinder unless we decrease the pin height or change the rod length. Ford chose to decrease the pin height. When Ford increased the stroke to make the 410 they changed the crankshaft and the piston pin location. Only the stroke and piston height changed. The rod length stayed the same, as did the deck height. (The reason the pin height only changes by 0.100 inches and not the complete 0.200 inches of the stroke increase is that the piston moves further down, 0.100 inches, the cylinder as well as further up, again 0.100, the cylinder.) Ford could have changed the rod but they did not. All rods for the 390, 406, 410, 427 and 428 and the same length - 6.49 inches. In order to correctly balance the engine with the pistons moving further up the cylinder bores, Ford added weight to the flywheel/flexplate. All 410 and 428 engines use the same externally balanced flywheel/flexplate. Note that all harmonic balancers are neutral balanced for the FE engines and therefore interchangeable.
Yur a good man Hotroddon! Much appreciate the info - and lesson. Ever need some info on metal m***aging, I'm yur man! As I said, I just bought a 390 (with 4 speed) from a 68 truck. Gonna go in my 67 Galaxie 550XL Vert (with the auto). Once the Gal's engine is out, I'll do the same to it. Cheers.
