Topic: Favorite Motors

[RT]

So far my favorite is the AMC 150 MPFI, however I'd like to say the 2.4 liter because the numbers look better, but I don't have enough experience with the 2.4 to be able and judge...

Have to go with the original.  The starter motor on my '43 GPW (sold long ago) was pretty bad so I usually just relied on keeping it running once it got started.  I could go all day without stalling that engine.  On the other hand, I stall the 2.5 MPFI all the time and that's with lower gears too.

we've found the starters in our cj2a and cj3a quite durable.. picking up the slack when we have carb or ignition issues... only had a starter give up ounce(bad tank of gas carb kept clogging..heavily abused starter..) and after finding a new bearing its been good ever since. but there is something about the go-devil where you can go down to a rpm  where anyone would swear its dead and it will fire and come back to life on its own... where as the fuel injected motors tend to give up life around 500rpm... the go devil just likes to lug and be in low rpms all day and if you remember to get a new distributor cap and rotor every year it will run like a top (all the wetness we go through takes its toll on them).. its hard to compare the 2.5l to the go-devil.. completely different motors that require vastly different driving styles.

I'm going to say the 2.5L MPFI since it's an evolution from the 2.5L Carb and 2.5L TBI.  Honestly, I don't know why anyone would choose either of those.  In which case the Pontiac 151 is a mean engine.  You can build it up to some impressive numbers.

Although I have to say the 2.4L is an impressive package since you get a better transmission which makes for a relatively simple swap to a 4.0L as they use the same bell housing bolt pattern.  The 6-speed is an awesome transmission that will hold up to something like 300HP and 300TQ.

Still for simplicity and just tooling around, there is something nice about the sound of a L or F head.
