Haha ya buddy!! That's what I'm talk'n about! Glad it made you think of my project. Were is this?

This is less than a mile from my house in Seattle. My wife would kill me if I got one of these, but I would like to see someone save them.

Oh man ain't that the truth, (the saving part )

Ah seattle, the most beautiful part about that city is Rainier. I was  just up in your side of town back in mid Jan for some tent camping on Orcas. So dead this time of year! It was amazing! Look for my Chinook up there in the time to come, someday I would love a road trip going up to that side possibly going into Canada , with some obvious 4x4 thrown in there along the way. 👍 . With in reason of course, I do have a 38 year old camper on back lol!!!

And I was doing to research on some of the threads, now I totally get the whole bumping up of compression and all, but I'm not entirely sure but isn't a high compression level motor not what I want to pull my truck/camper around. Or am i totally wrong on  this.?? And if I'm right should I seriously consider trimming down those donut lips on the piston heads. Is this necessary for my aplication.

So what do ya'll  think about that lip of the 22r block?

And I was talking to LC, asked about the charger (super), and he said about 40 -60 hp!!!!!!!!!!!! No offense but absolute whack sauce!!!! For 3000 coconuts! 😐😤

Have you considered a 3rz swap? It's really not that hard of a swap and 150hp. You will not regret it I love my 33rz swap.

[4xChinook4 [OP]]

It's been a heavy consider on my mind, how much did you have tied up in it in the end? Now I know there is a Butt load of info on this so I won't ask much. Just wanting to keep it simple, it's about as much work as expected with a swap > motor mounts, wiring, new tranny and t case, re lengthen drive shaft. I believe it's small and short enough no hood clearance, no body lift, no suspension  upgrade needed. Correct? I'm not the best with a welder, and fabrication isn't my fortè, lol so it probably wouldn't  be smart for someone skilled as me to attempt this swap, yet...
I've been hear diesel  though.... 

[4xChinook4 [OP]]

I know with a 3rz, right now I would probably  screw it up, and take forever. This IS my DD .

[helipilot77]

Did someone say diesel? 

[4xChinook4 [OP]]

Did someone say diesel? 

Haha yes someone did say the "D" word . I think you obviously have an opinion on this...

[79coyotefrg]

a 2f would put the number one cylinder in front of where your radiator is now I think.  and they are crazy heavy.  in a cruiser they are awesome but not in a small truck.
for your truck I would consider shaving the donuts but this needs to be done on a lathe.

Would it hurt me if I didn't though???

I probably spent around 1500 in parts and did all the work my self including wiring. It was worth it though! You have to do some fab work and welding. Engine fits in bay, need to get a rear sump oil pan though. Need a 3rz bellhousing  and custom motor mounts. Exhaust can be run under the trans back to the correct side. Not going in to all the details. If not good with a welder and fab work might not be a good option then. My 85 is a dd got all the parts and finished the swap in 3 days by my self. I put the taco dash harness in my truck and wired it to my igntion and gauges. That was the hardest part I think. There r plug n play harnesses avalible and bolt on motor mounts  but they will cost u. I'm getting better gas mileage and loads more power now.

Info thanks for posting,  ya we'll  leave the "3rz swap details" to the boards  dedicated to them👍, i agree  .  Thanks for posting it non the less. 👌

no, i dont think so. 

[4xChinook4 [OP]]

OK just making sure that this high of a compression motor pulling my camper, isn't a detrimental combo.

[79coyotefrg]

the main thing is to take a dremel tool and remove any sharp edges on the piston donuts and the edges of the combustion chamber. this reduces the hot edges from being hot enough to ignite the fuel mixture before the spark does.  One thing for sure. if you were to take the pistons to a machine shop and have them mill the donuts off that would remove the chances of that and would keep the compression low enough you could run 87 octane and still have a better than stock. much better I think because you would have a 2.4L 20R

[H8PVMNT]

Nice bro thanks for the detail with story.  And ya Glen IS the hybrid master, glad he's involved in this thread. And honestly I'll have to check my tach and speedo again, I'm out of towm till the end of the week(maybe longer), but if and when I get home I'll give a true estimate. But what was your top speed.? Cruising speed.?

5.29s and 32-33 inch tires I could do 75-80 mph on the interstate no problem in 5th gear, 20 mpg. Speedo and odometer will of course read faster than your true speed, so take that into account.

Higher rpms within reason doesn't kill your gas mileage on these engines.  Kind of like you typically get better mileage in 4th with a stock truck than you do in 5th on long highway.  I guess it's because you are into the throttle less when you are near the peak or torque.

Good knowledge, glad to hear that. I definitely  will consider re gearing for the right price. 👍☺

Haha sounds nice . I will defiantly consider this.

[4xChinook4 [OP]]

 hey guys, I just found GM TBI on Craigslist I might be able to get for my Chinook build. What is your guys's opinion on this? What do you think is a fair price?

[twistedtoy92]

$150

[4xChinook4 [OP]]

$150

Perfect! That's  sounds great. Now I think it might be a smart move. What do ya'll think?

[4xChinook4 [OP]]

Just got back home last night about to take her for a drive, lol Check out the cornice on her! Colorado

[4xChinook4 [OP]]

So I'm sitting at 2800 rpm, at 55mph. With about a 1/3 pedal travel. Just checked tonight in 5th on highway.

This is with 4.88s and stock tire size.

Stock 20r, weber 32/36, lce street header, and cat.

[4xChinook4 [OP]]

Due to the high compression of the hybrid,  when I build it, should I buy a head shim?  $28. Thickness is 0.020" combustion  chamber opening is 3.756"
 napa.

[4xChinook4 [OP]]

And the guy on Craigslist with  the GM TBI said $600. That sounds VERY high? Am I right.

not bad but do it again with it  in 4th remember 5th gear is an over drive gear and is weak.  Use 4th as much as possible when under a load.

NO, dont use a shim. get a multi layer steel gasket from D&J Rock or Toyota.   DO NOT USE A FELPRO HEADGASKET

he's smoking crack, walk away.

Understood,  will do. Thanks  Glen

And I think I'll offer him $200. . But that's if he actually seems like a decent guy, who deserves it. We'll  see how it goes. He sounds like a pretty cool dude so far. But like I said, >we'll  see .

[4xChinook4 [OP]]

Oh and he also has 5.29's  for sale.  With set up kits? For $500  ? With my 2800 rpm in 5th at 55mph  with 4.88s  and stock tires, should  I get the 5.29's  for when I get my 31's  or 32's Or do I sound like I'll be sitting pretty with my 4.88s once I put on the new tires.  thanks

[4xChinook4 [OP]]

Just finished the muffler and rest of exhaust, sounds much cleaner now .
