How are you going safely to fit 5 people in a Blazer?

But my vote would be a 502.

Realistically, we aren't wheeling much anymore. But this would be a completely separate vehicle, a family hot rod, not a wheeler. As I said, I have a nice SOA CJ7 on 33s in the barn that is for wheeling, if we have time. Something like the old toyota doesn't make sense to have anymore if it only gets used 1 or 2 times a year.

This thread has nothing to do with 4 wheeling, more was a question about engine fitment.

Look up Larry on CK5.com if you are considering an 8.1. He has a nice setup in his K10, but I think it's all "stock". A 12 bolt and D44(maybe chromo shafts) should be good if you have 33's or 35's, any bigger would be pushing it. With your power goals and intended use, the main worries I would have would be axle wrap and twisting the frame, both of which have easy preventative measures available. Fwiw, I'm not trying to tell you how to build your rig or say you don't know what you are doing, just trying to put out some ideas and maybe point out some things, since I don't know how much you already know.

You don't think that an 8, a 5, and 3 year old fit in the rear seat which has 3 seatbelts? The 8yr old needs no special seat, the others have booster seats that are about 14" wide each. Thats leaves more than 15" available for the 8yr old. The common swap to get nicer seats is to use a newer Suburban 3rd row which is a 3 person seat.

It would be 33s and open diffs, pavement and sand only. I am thinking some rear axle wrap prevention would be called for. 10-4 on the frame boxing

I have fit my 3 kids into the backseat of my K5. Its tight with two boosters and an infant seat, but it works. Take away the infant seat and there is plenty of room (sort of).

If/when you start this build, be sure to start a build thread. I will be building a K5 with a similar purpose in mind next spring, though with not such lofty power goals(for now) and any input on what works or not would be appreciated.

Probably will, but it seems to jinx my builds, lol...

First I need a vehicle. Hard to find any first gens, especially in the midwest.

It sure is. All of the first gens within 500 miles seem to either be rotted beyond recognition or $20k

I just remember riding in the back of my buddies, it was a bit tight for two adults.

In a dune bashing scenario, I picture three heads clunky into each other, but if it works, it works.

I was serious on the 502, you can get a turn key 500hp/550 lbsft for $8-9k. Bolt it in and romp!

Ok, I went overboard there I admit it.

Stuff a supercharged 3.8 in it and call it good. You will need to run premium but will make up for it in fuel mileage when cruising. It will be quiet, reliable, cheap, easy to work on, and have a good amount of power in stock form. A fully dressed ssei 3.8 is overbuilt internally making it quite heavy though. But, you can make some very impressive power with the 3rd gen's.


If you are set on a reliable 500hp. Look at a northstar supercharged LC3. 460hp/430lbs@3900 stock while getting around 20mpg in a very tight package.

Here is some internet jargon on it.

I have actually considered getting something small to stuff a supercharged 3800 into. Maybe a tracker? Not sure if that would fit since it's nothing more than a daydream and I haven't researched it. A Blazer is too big for a v6 though. That ls2 that's just laying around would be perfect since it's readily available.

For what you're talking about doing, I would do a simplistic BBC. Yes, you can get better MPG with an LS motor, but....how good of gas mileage do you think you're going to get pushing a 5,000lb vehicle around?
You can make 500HP in your sleep using a decent BBC, and it can be reliable as hell.

You want something with a lumpy idle that will turn head, rev like the dickens and be streetable - 427 BBC with Merlin oval port heads. Very streetable and very easy to make 500 HP. If you want to lighten it up a bit, put on AFR or Trick Flow oval port heads. Parts are readily availble and you have no issues with fitment since they use the same motor mounts as a small block.

So, if I look around my work shop, I have A) a 1971/2 Jimmy (VIN says very early 72), B) a nice LS2 aluminum motor (easy 500 hp with a cam swap), and a *fully* built reverse manual 700R4. I think that will be the way I go most likely, but it'll be a winter project. I think I will throw a 4" lift and some 33s on it first, and just do clean up.

I have looked at everything and for the price..you cant beat what you already have.ls and be done. I love fords..just not there for my pocketbook.love stroker motors and big blocks..just don't compare to price for performance of a ls.. I hate saying that but a ls1,ls2,ls3,ls6,ls7 are just awesome swap in and turn key motors.

I am thinking a NP208 or NP241 to be lighter than a NP208. full soft top, lose the hard top, get the weight down as much as possible.
problem is the 241s can't take alot of torque. even with the HD chain i've seen them break the case in half under heavy abuse. After seeing what you picked up and that its equipped with a manual and a 205 why not just run the manual behind the LS2? they are compatible with the correct components.

Because an SM465 isn't fun to drive, huge gear splits, slow shifting, would not give the kind of feel I want. And I have a fully KillerB built 700R4.

The overall feel is to be like a 4x4 muscle car.
