1971 vega 427sb "VEGATRON"

Postby black.fire.wagon » Tue May 27, 2014 1:39 pm

So I'm new to the h body world. Just found this one cheap when looking for a rolling chassis for a 427sb I bought last year.

Originally a vega 2300 mt. It was built once or twice before.

Image

It apparently has a 7.5 inch but I have to open it up to see what gear is in it. Update: it's a 3.42 mechanical locking diff, let's see how long that lasts

Image


I patched some hacked metal under the hood at the motor mounts. Must have had custom mounts. Some shoddy work here and there.

Image

Image


Installed my engine with front mount trans dapt kit. Some minor mods needed but welding is no problem.

Image


big rad

Image
Image

covered it with a custom spoiler using spare parts
Image

5 bolt conversion

Image

Image

Image

quicksilver shifter, hurst t handle, shiftkit installed (th350)
Image


15" vette wheels

Image

had to get a proper audio deck, not only did the oem not really work but i gotta have bluetooth audio to live
Image
Image

Been a while since i updated. Got the car back or of storage last month. Feels good to drive it again. Found my fuel tank is leaking. Can't find replacements so I'm sending it out to be sealed and coated.

modified some 88 sunbird seats to fit, the car had some poor fitting worn out firebird seats in it. these are way more comfortable
Image
Image

found a mint condition rear seat in the boneyard, made it fit (willing to sell/trade this) it appears to have been refurbished, the guy told me there were matching fronts but someone got to them first :cuss:
Image

found some more shinnanigans when i removed the fuel tank to have it repaired. pick up tube on the sending unit had been repaired with a hose and the sock filter just stuck onto the hose, but it had come off and was sitting in the bottom of the tank. explains why it would run out of gas before the needle even hit the E line. fixed it with some steel line and no need for the sock, i have an in line filter
Image

found some images of the engine before installing it, it was built well by the guy i bought it from. 400ci small block, .060, stroker, making it a 427ci. arp bolts, eagle rods and crank, big blick lifters. don't know what cam is in it though
Image
Image
Image
Image
Image

torquer II intake
Image

didn't take too long to find a small oversight when this engine was built, they used the sb rocker studs. so the nuts were only on a few threads. started snapping off the tops.
Image

if you look closely you can see how far down the locks are in the nut.
Image

easily fixed by finding a set of big block lifter studs. 2 days before leaving for Syracuse was cutting it close though.

replaced badly worn rear control arms with a nice set of adjustable umi performance arms.

Great progress!
I have a really nice gas tank out of my '72 wagon if you're interested. PM and I can send some pics, otherwise I'll be selling it soon.

if im not mistaken the 71 tank is unique, being a notchback makes it even less likely to be the same

It would appear that the fuel pickup mod was done to eliminate the original fuel pump.
What cylinder heads are you running on your SB 427?
The notch looks to be in great condition. Is it a Canadian car or has someone imported it?

The heads match the block. 400sb ported and polished. bb lifters. roller tappet. I don't know what's in it for a cam. It's got some lift for sure. Runs like a bb.

I'm hunting for sway bars. Specifically the rear that bolts to the lower links instead of the chassis like the a/m ones I find. As well as some backing plates for drum brakes

Far as i know it's Canadian. The quarters are rough. Previously owner put it into a guardrail. Need about 1-2k in panels. Previous build was pretty hacked. If looks ok at 60 kph or 30 meters away though :lol:

Bump for another hot rod season. Should be doing some body panels this year. Only place I see with body parts is http://www.showcars-bodyparts.com/vega.html.
Anyone know of any other suppliers?
