A Few Good Words

I was cruising the JP website and saw an article about the top ten jeep motor swaps. Here is what they said about the 225.

6. Buick 225 V-6 What: A 90-degree odd-fire torque monster found in early '60s GM cars and '66-'71 CJ-5 and CJ-6 Jeeps.

Why: The 225 V-6 will idle down to 50 rpm, gets great mileage, delivers more than enough torque for an early Jeep, and is just plain fun to drive and listen to.

Put it in: It's a factory fit in any CJ-5 or CJ-6 and drops right into a flattie. FCs and other oddball Jeeps can benefit as well.

I am glad you guys talked me into keeping mine. Saw my motor at the machine shop last night on the boring stand, the machinest said it needed bored out so we are going 30 over. I am excited to get the pieces back and start the build up. This site is the best!

 

yeah i read that exact same article.. the thing that caught my attention is that it idles down to 50rpm... thats gotta be pretty cool to listen to.. Less than one rotation per second!!

 

Link to article?

 

I am thinking 50 is a bit of an exageration... but if it isn't then I want to hear that.

 

Sorry, forgot to add the link. Here it is!

Maybe, mine will still pull down to 200 rpm after 300K on the clock.

 

200 I believe. but 50?

 

They're right about the Caddy 472/500 too. The rest seem kinda obvious or expensive or not really suited to Jeeps.

 

Hmmm, wonder if I can find a way to mount up the 225 in my XJ....

 

I have had my 258 down to about 300 RPM without killing it.

 

I used to have a '75 Sedan de Ville with the 500 in it. They're right about the torque...even in a car as huge as that, it would get up and move from a stop. I have a copy of a Hot Rod mag somewhere with an article about swapping one into an El Camino. Their big complaint was that they couldn't get traction, and spent a lot of time smoking tires :twisted: . When it did hook up it was pretty fast IIRC. There's not a whole lot out there for performance parts, but then you don't really need much with 500 cubes stock. If you want one cheap, just shop for the whole car...pretty cheap when you can find them.

 

I built a couple Olds 455 before, put one in a 68 camaro

Talk about cheap torque.
Too big for my flattie. But in a longer wheelbase you could just build it stock.
As I recall they are narrower than a CBB. Or caddie.
Fit real well in my camaro I could lift the hood at 75mph
I have a well built 454 600 horsepower 550 torque now, but just too big for my jeep.

 

So you know one of there editors is a member here... Im sure they dont mean it will sit there and run constantly at 50 rpm. My thinking is you could bog it down to that for a brief second or two then rev it back up to a more normal rpm. Where most other engines will die when it reaches that point, this one will keep chuggin.

 

Can these v6's be bolted into an Fhead set up with little aggrivation?
Meaning will the drive train handle the xtra power and would I need to move the radiator? This Fhead is constantly giving me grief and the power is ALOT lower than what I'm used to (highway) I know I'd still be limited on rpm's but I'd atleast not have a fully loaded rig crawling up my but going up a small incline strugglin to maintain 50 mph

 

My problem with the buick is finding one of those early flywheels.
i have the motor but it is cheaper for me to just get the vortec v6 and use that flywheel.
either motor will fit in our flatties fine actully shorter than stock with about double horse and torque.

The buick has the distributer in front as well.

 

The way I read it, I think he meant using the Vortec flywheel on a Buick V6, but either way, I'd like to know, too.

I don't know about accurate RPMs, but I've also had mine chugging down real low and been able to gun it and save it. In fact, I think my 2G is more of a limiting factor than the motor itself; the times I've had my RPMs that low also happens to be the times I'm on some kind of incline and the carb is tending to want to flood. My later model stuff tends to act erratic as soon as they dip below 500RPM.

 

The way I read it.. He is saying for some reason he can't find a 225 V6 flywheel, so it is cheaper to install a complete Vortec (with it's flywheel) instead of a 225 V6 (with it's flywheel).

 

Yes it sounded like he couldn't find a flywheel for the 225 which he had without a flywheel.
