2000 4.0 OHV swap to 4.0L SOHC

Anyone done it? Stock for stock I like my OHV but if I want to start modding it then the SOHC motor is a much better base to start with. I know the transmission can be "used". From what Ive read the trans will bolt up minus a single bolt. And from what I understand my stock motor mounts will also bolt on to the SOHC block. So is it as simple as engine, harness, computer? or is there a laundry list of parts that I would need to make a SOHC work in my 2000 OHV.

why do you think a sohc motors better than an ohv the ohv motor have a higher torque curve at a lower rpm and for what your building your truck for how often are you going to be in the high rpms?

3000 RPM is not high RPM. He wants an engine that starts off making more power. If the man wants a SOHC engine then so be it.

For the modablilty standpoint, the OHV just doesnt take to mods like the SOHC does.

I think your going to want more power then that.

Zachs truck has power, but it lacks torque....reason for his swap.

I would highly think about a V-8 swap of some kind.

if you're going to go through all that work, go for the extra little bit and swap in a 5.0!

furthemore, there's proably more info on swapping from a 4.0 OHV to a 5.0V8, than there is swapping from 4.0OHV to 4.0SOHC.

if that doesn't convince you, just think that nothing sounds as good as a piped up V8!

Zach did not want a V8 but can't stand the lack of touqe.

I just think it would be better in the long run.

So. My friend is running 36s on a 2.2 Yota engine pushing 60 or so horsepower and it does just fine. You don't need that much power if you have the proper gearing.

Well there are more gearing options on a yota but in the lowest gear he can smash on the brakes as hard as he can and the rear tires still break loose even at idle.

your friends toyota probably can't merge or pass on the highway very well!

i'm just saying, why go through the trouble of swapping in a marginally better engine, when for basicly equal cost and effort, an engine of superior power could be swapped, and likely not loose any fuel economy.

said engine will also respond to modification better also!

Some people don't want to do the norm. Like I said. Some people don't want or need a V8. Also it merges onto the freeway just fine. He has the proper gearing for the tires.

I have the proper gearing as well. IT makes power... just not where I need it.

I am going V8 only because certain things fell in place all at once.

I hate the 5.0, If im gonna go through all the work to swap in a motor that I couldnt use any of my stock parts with id go with a chevy 5.3L.

With the SOHC, I should be able to use my trans, and doubler/tcase which is why Im even considering it.

This wouldnt be right away, more just looking at options. If it takes to much to make a SOHC work then i wouldnt bother at all and I would just keep my OHV. The only reason im considering the SOHC is because if it will work with my current tranny then I can keep my doubler. My SAS has only taken this long because I was at school, and I didnt get summers off. It also didnt help that I changed my mind so much, leafs to coils to coilovers. That reminds me I still have the front crossmember I build for leafs sitting around somewhere. Now that Im done, Im just waiting for the warm weather.

The thing that even made me think about this was Zach taking his SOHC out of his truck.

For what it is it has horrible power out of the box. It makes just about the same horsepower as the SOHC does. Its torque is only like 20-30 more then the SOHC also. all that work for something that is marginally better then a SOHC. and I cant use my stock tranny and doubler/tcase with it.
