71 Jimmy
Hello guys,
My first project thread. Swapping everything I can off a 76 blazer into my 71 Jimmy. I'm not a pro, by any means, so this should be fun. I figured step one was tearing down my Jimmy.. I pulled out the carpet..and *gasp* soooo much rust, right!.... kidding..I know how lucky I am. And after reading through Jaros PO has me PO'd thread..I feel invincible. ![]() |

Re: 71 Jimmy
Small Update* Engine just about ready to pull. then, need to start planning the addition of the clutch pedal. I thought I'd be further along than this by now. Was working on it last night when my girlfriend came out and asked "When do you think you'll be at a good stopping point", which is girl code for "get done now."
will update again as soon as something exciting happens.; |

Re: 71 Jimmy
First thing to do......get a new girlfriend....
![]() I tell my wife when I go to the shop to work on mine, "see ya later doll , I gonna go make love to my Blazer". When it comes to rust, these old Blazers/Jimmys are like an onion......the more layers you peel back the more you'll find. Good luck with it! |

The 350 in the truck has a serious water leak going on. The exhaust port on cylinder 7 was spraying water like a lawn sprinkler. I'm debating on if I should get that engine rebuilt, or throw in the 305 from the donor truck (which seems to only need valve stem seals replaced) and call it a day. decisions, decisions. |

![]() JMHO, but i would go the easy button. Youll have enough challenges through the rest of the build. Put the 305 in it and at a later time build or buy a engine you want. These crate motors are unbelievably cheap, and a warranty ![]() Good look with you build, mine is stuck in electronics prison

Re: 71 Jimmy
Smaller update. Got the th350 and xfer case out of my 71... was delighted to find that the frame on the donor 76 blazer and my 71 were the same width.. a few pics attached.. I am wondering which trans cross member to use and if they are interchangeable. The 71 cross member seems a bit more heavy duty. Cant wait to get that sm465 in my 71.

Re: 71 Jimmy
Yeah, I'm starting to love it more myself. The radiator support, both inner fenders and one of the Outer fenders has rust. The perfectionist in me wants to buy all new ... the cheap dude in me who buys all his clothes at Target wants to try and fix the rust.

Re: 71 Jimmy
Hey Guys,
Dug into my truck some yesterday after playing hooky from work. Pulled off the inner and outer fender to get a better look. Found some trouble spots and busted out the grinder. The further I cut, the more I found. I'm going to try and weld a legit piece back on..I figure, If I screw this up, I'll buy a replacement. |

Re: 71 Jimmy
And finally, The inner fender. I'd have to guess the Prev-o had some kind of battery issue at one point? because the metal is totally gone directly under the battery and , the battery tray seems fairly new..but I'm no chemist.

Re: 71 Jimmy
That area is pretty indicative of a battery spewing acid, mine went all the way back to the heater box. One of the reasons i put in a gell core battery.
Keep plugging away, you ll find all kinds of things the PO neglected over the years Good luck with your build I ll watch

Re: 71 Jimmy
I have this if you don't want to make one, actually I have both sides. I've been making a pile of parts to sell.

Re: 71 Jimmy
Hi warbucket! I truly appreciate the offer..but I bit the bullet and ordered a radiator support, inner and an outer fender. I'm notvery confident that my welds would be up to snuff.

Re: 71 Jimmy
Updates and questions and info..oh my.
So, I dropped the 305/sm465/np205 from my '76 donor Blazer into my '71 Jimmy that had the 350/th350/np205. Some things I noted: 1. The stock exhaust manifolds on the 305 had to be removed to allow the engine to sit flush on the mounts 2. After removing the exhaust manifold, I noticed the oil pan had to be removed as it was resting on the cross member below the engine... 3. The sm465/np205 line up on the tranny cross member in the same spot as the th350/np205 did but, I had to remove the rubber to make it fit though My question for you pros out there.. how different are the stock auto and manual transmission cross members for the '71? The only thing I can assume is that the manual ones are a bit deeper. I'm going to get my search function on and see if this has come up in any other threads. |
