3v heads on a 2v engine??
I might be doing head gaskets soon but I really hope not. Depends on how my truck shakes down.
My question is will newer heads work on my application? I have a 99 V10 2v, and will i see the same power number that the 3v puts out? What all would have to be changed if I can do this?
Does anybody know if there are performance cams out there for a V10?
Thanks

I have a 2000 2V E-450 SD, and have never tore it down, and hope I dont need to, but I would think its not a drop on part, you know at a minimum the cams would need to be changed, and the intake, and I'm sure someone makes hot cams for that engine.
You might go to a good parts house and ask to look at the two different head gaskets, one 2V and one 3V, that would give you a good idea if the heads are even close. And I doubt it would work, it just sounds like it wouldn't.
But good luck, and if you do it, please keep us posted.

I don't recall anyone who makes a stock replacement and/or performance camshaft for the 3v or 2v V10. If some does know of a maker I would like to know as well.
As for the interchanging of the heads I don't think you can. I can't recall anyone doing so.... I may be wrong But im perrty sure they don't bolt the same.

I know comp cams will make a set off V10 cams but they are pricey. Some other companies may make cams for the V10 also. A ported set of heads (either PI or Non-PI) and a decent cam should put you closer to what the 3V puts out.
MWSF250 just did an engine swap on his truck where he put 2V PI heads on a 3V short block. I'm shure he will chime in. The 3V heads will need the 3V intake also and the 3V intake uses a variable volume setup which is controled by the pcm.

Good news is that the heads will most likely not have to come off my truck so I probably will just try and find a set of cams. Talked to some machine shops today and they are looking into it for me. I might sell this truck and buy a 3v V10 auto as it"s replacement.
Thanks everyone and I will keep you posted as to if I find some cams.

mwsF250 piping in here...
The 3V heads WILL bolt onto 2V block. Can use either time chain, sprocket, and crank pulleys. Do have to use 3V cams and cam pulleys.
But.
The 3V heads absolutely require 3V front cover, exhaust manifolds, and intake manifold. These are all radically different. The 3V is cross flow, with WIDE ports. 2V is old fashioned side by side valves and offset and tall narrowish ports. Are accessory drive conflicts as well (6 rib instead of 8). All bolt on stuff, could be done.
BUT. The 3V is throttle by wire. To have it work, you need '05+ ECU. And need to modify wiring. A lot more work, but doable.
BUT. There are no '05+ ECU's that will talk to 4R100 trans. Would have to be stick or convert to '05+ Torqshift trans. A lot more cost, but doable.
BUT. I was told all '05 trucks use CANBUS for wiring, including the entire dash, rather than discrete wiring. I gave up at that point.

The dashboard, the ABS system, the airbag system, everything, is now CAN.
Very hard to do without all that.
I'm sure it's doable. If I had a project truck, and a complete '05-up donor, I would surely try it. But it would probably involve changing EVERYTHING electronic over to the newer system.
And then what do you have?
Better off strapping a blower on a 2-valve.

Yes, the 2000-2004 2V PI (performance improvement) heads, cams, and intake manifold. MUST use PI intake with PI heads. Port shape is different. PI intake also has much shorter runners. Cams do not have to be swapped, but rumor has it PI has a slight increase in lift.
Everything else will change over from '99.
Not a huge bump in power by itself...
Non-PI: 275hp, 410tq
PI: 310hp 425tq.
I only proceeded because one of my heads was shot and needed to be replaced.
BUT, the larger ports and shorter intake runners will breathe better at higher RPM, so other typical non-boosted add ons should, theoretically, provide more benefit on the PI than on non-PI. Cams, headers, etc.
