Can anyone figure out how much better the v10 could be if it were in a 72 degree block rather than sharing the block layout with other v8's? They've had to add a couterbalancer to offset the engine firing order imbalance and it also makes me wonder how much power is lost by irregular firing space.

lets not forget this was built to use as many parts as possible from inside and outsides of the 4.6 and 5.4 motors. changing to a 72 deg block who knows what would be. dodge like? as they still use a commom crank throw like a v8 in thier v10.
and something we may never know as . with ford right now a v10. can not be ordered again for a 08 -25/350 in the green states. so it's days may possibly by numbered. in a light duty truck "1 ton and under"

 

Maybe that is also the reason for the emphasis on the F450's? Eventually the gasser may still be around, but limeted to trucks above 1 ton. I think they have enough v10 customers from the fleet ranks to keep it around. Does that mean the F350's and F250's will get a supercharged 5.4?... LOL...

I just read last night that one common misconception about the 'modular' nomenclature is that the engines were designed to use parts interchangeable with each other. Other than water pump, alternator and similar front end items and possibly the oil pump and maybe pistons, I'm not sure what else is interchangeable. The name modular from what I read was refering to the convertability of the factory assembly line in being able to switch from making one of several engines in the ford line. (according to Wilkepedia)

Anyhow, I know that the engine is just fine, but I do sometimes notice a imbalance 'buzz' or vibration that I dont' find in the v8's. I had thought this was due to a missing cylinder in my old engine, but the newer 2000 engine does the same. I think the vibration is part of the cause of the commmon problem of heat sheilds breaking at the welds and other places.

The V10 configuration is not an inherently balanced design like an Inline6/V12. It can be balanced with crankshaft counterweights as an odd firing 90 degree Vee engine (BMW M5, Dodge Viper). It can be balanced with a balance shaft as an even firing 72 degree engine, or with a split crankshaft journal 90 degree Vee angle (Lamborghini Gallardo, Ford 6.8 V10).

heat sheilds please don't remind us man. the one on the front of the trans/lower bell houseing is the biggest noise maker.

you bring up a nice item with the bmw / dodge/ mb v10's as thet where designed from day one to run with only half the motor when in fail safe and now as a fuel reduction saver on the highway. those motors even have 2 pcm's, 1 to control each side. back in 87 i saw the first bmw one running on half a motor come in to the shop. if it hadn't been for the power losse i doubt the customer would have known it."his name is paul newman"

and if you look at vw's 5.0 L tdi v10 they do the same as ford split the rod jurn. to even it out.plus run 2 pcms. 1 each bank. now if any one wants to see a complicated motor thats the one. alloy block.plasma harneded treated bores. forged steel crank web, pressed and bolted into the block casting and forged steel end plates to help stiffen it all up. to fail proof. i think i still may have the dealer book some some ware. glad i don't have to fix them any more.

 

I tend to think that the V10 would be much less "vibratory" than it is if all the rod/piston assemblies were to weigh EXACTLY the same, and the balance shaft was perfect.

I'm wondering what the lee-way is on weights for the piston/rods.

Someday, I'll find out what the difference is
