To be honest, with my luck on blowing 8.5" 10 Bolts to pieces, I am a bit cautious to start power braking just for the fun of it.

I just upgraded my ten bolt with 3:73 gears and 30spline axles from a 90's truck and a true track diff and a t/a stud girdle/cover. With some moser axles and strange c clip eliminators the 8.5 and car 12bolt are close in comparison

Although I agree with those upgrades a 8.5" can be built very stout, I don't have that much faith in my stock '87 28 spline unit and I am tapped on 'toy' funds for the time being.

I know its to the wheels, I meant personally I'd be happy with numbers like that at the crank. That's actually the power level I'm shooting for with my 383. I hear you on skipping unnecessary driveline abuse. I'm hoping I didn't "over tire" mine. Anyway, if you ever make a rolling vid I'd like to see it.

I misunderstood your meaning, sorry about that.

I'll see about getting some video shot from another car while driving.

What kind of MPGs are you geting? Awesome build. I hope to start on my 91phone 4x4 2wd ls conversion soon

I get about 14 in town and 18 on the highway, but I tend to drive pretty aggressively.

Well when you do get the driveshaft dynamically balanced and some 1350 u joints and the ten bolt built and your good for 600 to the wheels

Truck looks awesome.I know this is an old thread, but did you ever sell the rollbar? Is it aftermarket?

Sold years ago....

It was built from a kit from Competition Engineering.

dman1982 · 10-28-2014, 12:04 PM

not sure if you did this already or not, but with my short bed k10 and 4l60 i was able to use the drive shaft out of a 2000 camaro/trans am, pretty much the same length u joints, but weighs a lot less....not sure if it'll work with the 4l80 or not but just a thought

The conversion has been finished and driving for over 2 years. The 4L60e and the TH350 share the same transmission slip yoke, but the 4L80e uses the same as a TH400.

how is the blazer 2 years later?

Ford Assassin · 03-14-2016, 09:38 PM

4 years later since the conversion....

6.0 turbo setup made 690 to the wheels, hauls ass.

Ford Assassin · 03-14-2016, 10:18 PM

I also ditched the 8.5" 10 bolt for a 9.5" 14 bolt, custom 5x5 axles, Detroit Locker, 4.11 gears, etc.

One of my favs on here, will be using the pics when I get around to my full convert conversion. Now you just need a 73-80 front end and youll be done lol

No no. If I do any changes to the front end, it would be a '89-'91 headlight/grille/core support swap.

I like the square look vs the rounded off look. To each their own.

mjbdesigns · 06-10-2016, 06:07 PM

Considering attempting this same conversion (4wd to 2wd) and wondered if you may have a cheat sheet on the major components needed to complete the swap? Especially now that you've done yours from what you've learned...
I also worry about having to drill holes to mount stuff up front as I hate to drive down the road sideways....
