What engine do I have?

[Red beast]

My truck is a 95 4x4 4.0. I'm trying to find out which version of the 4.0 I have. Mine has the plastic intake plenum. It is different than my brothers 93 and my uncles 2003. I want to do some work to my engine to get some extra power. Knowing where to start would be great. My truck has 250000 on the clock. I know the trans and clutch etc. Have all been rebuilt. Not sure about the engine though. It doesn't seem to have the power it should. The power is missing all the way thorugh. Bottom middle and top. It makes its power band right about 2700 to 3200 rpms. But it isnt fast by any means. I've had this truck for about 6 months. It's runs perfect but it seems like it is missing a few ponies. I would like to get ideas on how to wake it up a bit but I don't want to go crazy. If my engine is tired I'm going to wait till it goes and rebuild it with a few extras. Or find a used one to start building up now. Im fairly new to rangers and 4.0 engines so I'm trying to figure out what is worth the money and what's not. My truck is a daily driver with a mild lift and 31 inch tires. I'm not building a race truck but I would like a little more power. Any shove in the right direction would be appreciated. Thanks

you have a ohv 4.0

yep you got a push rod motor.

If original and not a mid-94 build date, it should be a 95TM OHV 4.0

You can confirm it by finding the casting number on either head, or the block.

So am I correct that they are the same till 2000? My brothers 93 has a metal intake and mine has a plastic one. What are the differences?

dude use the info section on the page here, yours musr be a 95 casting as anything newer that that has an aluminium intake.the best place to look for what year your engine was built is by looking at the oil pan it will who 9_TM- ______ just so you know.

There are major differences, there is a nice explanation in the tech library, in the engine section, under 4.0 rebuild. Or something like that.

Motor mount holes, heads, pistons, all kinds of stuff.
