476 Install Pictures

[Frizzle Fry]

I put a new cam, lifters, intake, and carb on the 396 and the bottom end couldn't hang with the new-found power...




Crazy thing is that it still ran with the piston like that!

I know, I know... don't bolt nice parts on a tired bottom end...

So I built the 476 from a freshly machined block (454 +0.100" bore). Bought the assembled shortblock and heads, and slapped it together with the existing bolt-ons. I had to buy another new cam and lifter set though bc the comp lost a lobe in the process.

It's very healthy but I have yet to really get on it because it's still breaking in. After I change the oil this weekend and get some dry roads we'll see what she's got...

Here's what the engine bay used to look like


and you can see the destroyed piston prior to removal here

it had studs for a windage tray so I had to get one... (note the small block mounts I used thanks to a FAQ from this board)

New combo goin in with the help of some expensive labor (476/TH400):

[Frizzle Fry]

I removed the wire guide on the firewall and re-routed the wires to clean things up. I also took this oppertunity to finally run the proper 12 AWG wire to the HEI.

few more parts...

When I fired it up for the first time I had a heater core leak! So I figured it was a better time than any to replace it. What a pain that is! While it was out I had no choice but to paint the heater box... You can see the Accel billet HEI, painted brake booster, and new/painted MC here too:

Wicked! That Burb is gonna be a true sleeper!

That is awesome, thanks for all the pics and details! Quick question did you disassemble the A arms and steering linkages and what did you use to paint the frame? Did you sandblast it or just degrease and paint over rust?

[Frizzle Fry]

Thanks. I cleaned it with carb cleaner and a wire-wheel/brush down to bare metal for the most part. I painted just the area you see in the pics. No rust though. The 1/2" of oily muck must have been good protection.

Looking great - sounds like a stout engine! I haven't read your 61 Stepside build thread in a while so I'm gonna jump over there - if any of you haven't checked out that thread - you really need to!

[Bob Moore]

Great job. What brand/part # are the headers?

TIA - Bob

Looks like a clean install (should get it also), Digging the polished s200's on Burb

[70GMCer]

Looks great!! Although I see someone was sitting down on the job in the back ground.

[Bishops Trucks]
