What a nightmare!!!! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Classic Heartbeat** · 09-28-2002, 12:33 PM

I have been installing a Big Block 402 in this hienze 57, 71 chevy truck and here are some of the things you find out that have been done to a truck over the years..... I thing that longhorn man's dope smoking old man has owned this truck previously....LOL
I struck an agreement with a customer of mine to pull his small block 350 out of his supposed 71 Chevy SWB truck and install a big block 402 into it. Here is what I discovered about his truck:
1) This 71 Chevy is setting on a 67 frame!
2) This 67 frame has a 73 or later front disk brake system and crossmember! You know 67 frames are different than 68-72 and are not set up for BB.
3) This truck has a 67-69 rear end with 71-72 axles and 75 or 76 finned brake drums..
4) This truck has a 68 left front fender!
5) It has a 67 right front fender.
6) It had a V-8 set in the 6 cylender possition.
This truck has a 90 or so sportside bed..
The only thing 71 on it is the cab!
I could probly go on for hours, but you get my point.
Some good things to be said are that many years are either interchangeable or are with minor surgery..LOL
Well I have added to this truck's pedigree by shoehorning a 72 Big Block 402 out of a GMC!..Hahaha!!
Everything had been Mickey Moused in the truck previously, but after much frustration and hair pulling it is almost ready to send to it's owner!! Tomorrow it should be finaly done... It has only taken me a weak!! Every time I turned arround I had to either modify the truck to accept what I was doing, or fix something someone else messed up.
What is the point of this post.. Well fist off be carefull of what you perchase and reserch it if at all possible. Second point... I'm venting!!! LOL 3rd point, No matter how bad the situation gets, you can fix it!!!! Just put your mind to it and don't let the road blocks get in the way!! WES www.ClassicHeartbeat.com

At least you don't have to travel to town and back everytime you need a part!

**Classic Heartbeat** · 09-28-2002, 02:45 PM

LOL.. Spoof you are right about that on most of the parts... However I don't generally stock parts for the engine... So I had my share of running in and out of town...... LOL WES www.ClassicHeartbeat.com

JD72 · 09-28-2002, 05:08 PM

Wes,
look at it like this, at least its not ford.

Huck · 09-28-2002, 07:13 PM

WES, the best part of this experience is that you get to give the truck back. It could have been worse like---your son bought it and paid twice what it was worth!!!!!

Longhorn Man · 09-28-2002, 10:00 PM

Wow...didn't know the old man made it to the left coast.

I really hate that man.

**Classic Heartbeat** · 09-28-2002, 10:30 PM

Hey Longhornmail, your dope smoken old man realy gets around... Especially for an old guy!! WES www.ClassicHeartbeat.com

**Desert Rat** · 09-28-2002, 10:34 PM

I love BB changeovers,and for keeper trucks i use 67 GMC frames,not cut for BB towers but thats easy!!!! and NO vin numbers on the GMC version,also the 3 SB 67 GMC's ive parted all have Factory 1 pc drivelines.

Longhorn Man · 09-28-2002, 10:48 PM

That's how my 69 GMC is. Coil rear, short TH350, and a 4 foot 10 inch drive shaft.

**Classic Heartbeat** · 09-28-2002, 10:57 PM

Well I had to have one made..LOL If anyone is interested, a BB installed in a SWB in the correct position with a T-400 transmission will require a 57 1/4" Driveline... WES www.ClassicHeartbeat.com
