Tom Morana!
Has anyone seen their new stuff for the 3.0?
Tom Morana Racing Engines
Some cool stuff. Wondering if that supercharger kit is for the M90? I sent an email and asked a few questions i'll let you know what i get back.

Because the 4.0 is a worse design than the 3.0...
Rod ratio, when extracting every little bit of horsepower out of an engine and building something capable of lasting in endurance racing, rod ratio becomes very important. The higher the better, endurance motors usually have a rod ratio between 1.9 and 2.2. The 3.0 has a ratio of 1.76 and the 4.0... 1.55. Here is a "short" list of what raising that ratio brings you:
Less rod angularity
Higher wrist pin location
Helps resist detonation
A lighter reciprocating assembly
Reduced piston rock
Better leverage on the crank for a longer time
Less ignition timing is required
Allow slightly more compression to be used before detonation is a problem
Less average and peak piston velocity
Peak piston velocity is later in the down stroke
Less intake runner volume is needed
Less rod angularity and piston rock promotes long life at any RPM by reducing wear and with less piston rock, better ring seal.
GM understood this principle when they needed an engine for Trans Am racing in the late 1960s, that still met the displacement limitations. They could of tooled up a 305, but what they produced was a 327 and 283 hybrid, resulting in a 302 cubic inch V8 with a very high rod ratio and with production performance heads it produced 403.8 BHP @ 7,400 RPM. The best factory 350 of that era, the ZQ3, could only muster 300 BHP.
Displacement is not the be all, end all, it's what is inside that matters and it is scientific fact that the 3.0 has far more potential than the 4.0.
But we can go back to hating on the 3.0 because it is the cool thing to do.

There was someone that did everything you could do to a 3.0(stroker kit, forced induction, etc) and he was disappointed with the end result. I understand you can make a lot of power with a small displacement engine. Useable power? Probably not. Some engines just aren't made to produce power. In the end its a turd. My 4.0 is no better.

Im sorry but after swapping in my 5.0 from the 3.0. I hate the 3.0 that much more. Im sure the 3.0 would be perfect for a lighter vehicle such as a car. But for me in a TRUCK, no way. I dont even know why they considered the 3.0 in the truck. The motor was a dog before i lifted it and it was a bigger dog AFTER i lifted it. So i continued to beat it up until it blew up. And now i say hello to 5.0 and ill never look back.

lol i like how this popped up because well bullseye is running a 3.0L yes 3.0L ranger running at 500 or so horsepower. Im sure if done right you could get 600 or so and still last a long time because of the rod stroke ratio (as mentioned before). My theory is build it for power up top and boost down low. so you have a **** ton of pull all the way through. if you built a 3.0L to run up higher like the 7,000rpm range. and start getting boost at around 2,500rpm that sucker will pull. add a small shot of nitrous to spool even quicker. Its not always just about the horsepower but the power range. and if you build it for top end and then use boost and nitrous low end you'll pull a HARD!!!!!

I think its funny that I'm not the only one with this opinion on the engine yet you choose to pick on me.
#17
Even with that, look at the Ranger's competition, how many of them are V8 powered?
#18
Yeah that is what I mean. He bought everything. So what though. Its still a turd no matter what you say. Even if you actually use your DOHC head which you probably wont do anyway.

As for why you, it because time and time again, when someone asks for help or an opinion about the 3.0, you always seem to pop up with your educated opinion on the matter.

Actually I am doing something about my truck. I'm saving money to buy something else. Ever heard of that concept? And I'm sorry that my complaining bothers you. I didn't know this was your internet. Oh wait. It's public isn't it? Too bad for you.
Well again the 3.0 is a turd. I'm not the only one that has said it. Funny how you didn't log in for a while then all of a sudden you pop back up. Maybe because you couldn't make friends on the other forums. Who cares though. This is my opinion and I'm sticking to it.
I still don't see a your DOHC 3.0. Where is it?

if you talking about the 3.0L duratec which is a DOHC it is possible to make it fit it is 25" wide from the the end of bank1 and bank 2 the only snag is that i believe the heater? and blower motor gets into the way of the head... unless you can find away to move the "big box" on the left side of the engine bay then you cant get it in there. i have no idea what the big square/rectangular box is thats right next to the left of the engine. is that the heater box?

how would that work? considering that the cam is in the middle of the block? im sure that you could but that would be a lot of work. and if i had a SOHC or DOHC i would be talking to the Coates industry to see if they could make a Rotary cylinder head for the motor. Now that would be a sick setup!!! but yes back on topic. I could see pushing plenty of power out of the 3.0L one of its biggest problems is the ****ty heads. If you get over sized valves and backcut the larger valves and to some heavy duty work to it you should be set.
