455 Oldsmobile - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Not like my ADD shop doesn't have enough going. I'm in the middle of a engine build for my Cutlass. Just got the heads back tonight. Time to start a thread!

**Yukon Jack** · 07-25-2011, 11:34 AM

I've got a 455 Olds in my 80 Trans Am so will be interesting watching this thread. My motor appears to be very tired. What all are you doing to yours and what numbers are you expecting?

NONHOG · 07-25-2011, 12:57 PM

Well I'll start with the heads they are C's which had hardened exhaust seats
The way I got them. I had larger 2.07 SS intakes installed and stock exhaust valves. Back cut valves and some mild porting. Smoothed the EGR bumps and tear dropped the valve guide bosses.

Running a Engle cam JM 20-22 that has .496/.512 lift. 266/274 adv. duration
226/230 @.050 on 110* lobe center
Had the machine shop balance it, install ARP main studs. Already had ARP rod bolts when I got it.
Still need to degree cam. Get a fastener kit, gaskets, and figure out my oil pan. Mod one myself or find some cash for a deep sump moroso/milodon ?
Might add an accusump for extra protection.
Similar builds have seen about 380HP 500+ lf lbs. with W/Z manifolds.
I'm on the fence about running headers. (getting old

)

Sounds great - really like those valve covers. Looks like enough trunk to fit a SmartCar - I like it!

BigRed76 · 07-25-2011, 06:04 PM

Where did you find the valve covers? I Love them

Its got that full size look to it. Some kids at work asked me as I was pulling in to my parking spot at work if I felt like a pimp driving it.
Later someone asked me if I had to have a fog horn.

Covers came with the car, package deal.

BigRed76 · 07-25-2011, 06:21 PM

I am also curious, have you chosen pistons yet?

Sorry thought I put that on there. .030 SP 2278P forged not the best out there but not a high rpm screamer so they will do fine. And they came with the car!

I was just curious because I recently rebuilt my 455 very similar to what you are doing, but mine is stock dish pistons and stock cam still (.440/.440 Lift).

I did mine in gold, once its complete its a pretty overwhelming color

I like it gold with oem valve covers, yours looks great. I did not think the polished valve covers would look as good with gold.

Thanks. I agree with you on the polished valve covers. I don't know how close my gold is to the original Olds gold paint because I just used the only gold engine paint I could find. I originally wanted to use taller valve covers so I could use roller rockers, but I went with stock valve covers and stock rocker arms for now since I left the stock cam in it.

Yes I am refering to the Gold Rocket engines. Not dissing your build, Gold is the "norm" for under '74 Olds engines like Orange is for Chevy. Mine is still factory gold, but it is a lowly 350.

I did not think you were dissing. I've seen enough of your post to somewhat know your humor. My 70 455 (junkyard take out) is blue. My 425 (in the Cutlass now) is so dirty greasy I can't tell what color it is. I've read that 68 and 69 are red (455's). You have an Olds 350? In what? Not too many Olds guys will agree that a 350 Olds is lowly.
Pretty sure my 70 Cutlass had a gold 350, that was many years ago.

BigRed76 · 07-27-2011, 01:10 PM

I believe from what I read about Olds engine colors a while back that 455's of any year were never painted gold. I think it was only the 350's.

Oh I like the 350, but it is no 455. It is in a 74 Omega. It really was gramma's groucery getter, 4 bbl and all. Then it passed dad, and now me. My daughter want me to fix it so she can have it. I really need to do it.

Could be. The only factory 455's I have seen were from post 75 when they all went blue. I did see a rebuilt 455 in a 442, it was gold but far from factory, so it really doesn't count.

chevyrestoguy · 07-30-2011, 11:53 AM

That is going to be one cool Olds. And from the engine specs you provided, it'll haul butt, too!

I think those 'Vette wheels look pretty classy on there. You don't see those too often.

Heavy Evy · 08-16-2011, 06:37 PM

I swear I've seen a pic of that car burning the tread off those tires before....

Thanks! I'm still on the fence on those wheels on this car. But money is tight so they stay for now.

I had posted a burnout pic somewhere? Here? ClassicOlds? anyway here is a burnout vid. Only 400 some hits, funny that the Doodle bug minibike 6.5hp swap has 4500 hits. Wheres all the Olds burnout fans?

http://youtu.be/fPZtCZWASPU

No updates on the 455. All I have done is ordered my gasket set and engine hardware. Still have to degree the cam and get ARP headbolts.

lwing18 · 04-17-2013, 04:53 PM

Anyone put Headers on these old motors. I got Gold 403 I stuck in 66 C-10 but can't seem to find headers that will fit. Any suggestions?

I'd think engine bays would be close to the 67-72? Best confirm that.
I think headers are discussed here.

Thanks Nonhog. I was wondering if someone had a part number. I've tried 2 so far with no luck. Hooker and Hedman make about three different pairs each .

Think I might have narrowed it down to these but not sure.
