did all the basic bolt on mods but am still looking for more power mainly to tow a boat. Am considering either a v8 swap ( though seems like too much headaches) or swapping the cam and possibly heads. Vehicle need to be retuned after cam/ head swap? Thx

 

unrelated but your quote in your sig is about a 3.0 v6, no one really complaines about the 4.0 considering its the better option for rangers.

 

The 4.0 isn't fantastic.....it's a great option over the 3.0 but it's no V8 or a modern day V6 with 300hp or anything.

 

no one has experience putting a cam and / or heads on a 4.0 ohv?

 

I dont know if this guy is a member on here or TRS but it's a very awesome 4.0 OHV...looks like about everything that can be accomplished on this engine.

i have a cammed (comp 422), ported (stage 3 heads, stainless valves, dual springs) 4.0 ohv.. i didn't put the motor together, bought it from a member on rps.. however, these motors are so simple it's def not hard to install stuff in. my truck makes 190 rwhp n/a

 

That was in my sig for a while. Yea the 4.0 is better then the 3.0 but that can be said for both. Mk4 dubs made as much power as my 4.0L and did so getting 20plus mpg.

Edit: why did you swap out the 6 in yours in favor for an 8?

 

any huge difference between the 2 comp cams? have thought of getting the ported heads ..just can't justify the cost. maybe if i was single and still living at home lol I have a spare lower intake manifold that I keep meaning to port/ remove injector bung protrusion on

 

porting the heads will make a huge difference..

the two different cams:

410 - more for low/mid range hp
422 - will move the hp range up higher

My truck put down that HP with straight pipes and a tune

 

His is older

 

SOHCs are 205hp stock
OHVs are 18?hp stock

 

 

the sohc motors make 205 to the crank in stock form..

the ohv motors make 160 to the crank in stock form

 

thanks thats an informative rad.. i read the 410 is best at what i am looking to improve low/ mid for towing...95% of my driving is below 3000 rpm the 4.0 ohv doesn't seem to be a motor that likes to be revved that high imo

 

The sohc does.

 

OHV is more low end than the SOHC for sure.

 

yup.. if you are wanting more low end/mid go with the 410 cam..

 

anyone know of anyone that carries the 410 cam with all supporting components? compcams says need new valve springs and pushrods but don't carry the pushrods

 

tried Jegs as well...no one can get the pushrods...no one market the pushrods? confused as to why they market the cam but not the pushrods ( they need to be different length as reground cam) wtf

 

no one has done this? truly can' t believe comp cams doesn't even know the length of push rods needed..just tell need longer- most they have told me that i need to measure and then order the correct ones... i know at least camcraft also makes cams but would prefer to stay with comp cams as more known imo- though this is changing my mind if worth putting a cam at all
