476 Install Pictures - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Frizzle Fry · 01-20-2007, 07:36 PM

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

Frizzle Fry · 01-20-2007, 07:41 PM

Frizzle Fry · 01-20-2007, 07:44 PM

Painting the new block

Frizzle Fry · 01-20-2007, 07:48 PM

Heads on

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)

Sweet. Looks like a nice clean job. Wish mine was that nice. Talk to me about the small block mounts. I am putting a 396 into my 67 4X4. The mounts on my 327 have a single stud that mounts to the crossmember, not clamshell type, will they work w/ the 396? Also what clearence issues is any did you have. Thanks

what if you don't run this wire? What are the draw backs? What is AWG?

Thanks

American Wire Gauge I ran without it for a while (with stock wire), but the HEI draws more current and should have a bigger wire accordingly. The drawbacks are that you can burn up the stock wire and/or the coil with undergauged wire.

No clearance issues. I suppose you could have exhaust fitment issues if you went from normal BBC mounts to this set-up. I didn't because I re-did the exhaust when I put this motor in.

Frizzle Fry · 01-20-2007, 07:59 PM

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...

Frizzle Fry · 01-20-2007, 08:04 PM

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:

Frizzle Fry · 01-20-2007, 08:13 PM

Here's all the specs and some final shots for now:
* 476 (454 + 0.100 for 4.35)
* Heads: 336781 oval, 118cc chamber, 256/114cc port
* Pistons: Speedpro -10.5cc dome with above heads makes 9.5/1
* Intake: Edelbrock Airgap
* Carb: Edelbrock 1411 750cfm
* Headers: 1 3/4" primary 3" collector full length neck down to 2.5" post collectors through dual flowmaster 40 series. No H or X yet.
* Cam: Lunati Voodoo Here's the link to my cam specs: http://store.summitracing.com/partde...0&autoview=sku
* Accel HEI with "supercoil"

and I have full roller rockers to go in when I have the time (they were delayed in shipping so they didn't make the build)

*Billla* · 01-24-2007, 02:02 AM

Man, what an AWESOME thread! Cool, if sad, broken parts pictures, great build, great to see the kids out with the truck and one swee engine.

You ge rep points from me, dude

JAKES 68GMC · 01-20-2007, 08:26 PM

Wicked! That Burb is gonna be a true sleeper!

65-72 chevytoys · 01-20-2007, 08:52 PM

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 · 01-20-2007, 09:41 PM

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.

**Yukon Jack** · 01-20-2007, 10:00 PM

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 · 01-20-2007, 10:09 PM

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

TIA - Bob
