You should pay attention. Because you are wrong Nick thought the stock one could make more power but he was wrong the performer made more power. That was also on a small block olds.
The Performer intake on "Nick's Garage" was NOT "holding up the show", and he ended up putting it back on after he tried the stock intake. Watch the episode again, and you'll see...
if you drove a car with an olds V8 you were driving the best you could buy.....it got no better for an overall quality and smooth running and the engine sound was like no other...for real!!
I had a 1966 425 punched 40 over with the W-30 stick grind camshaft custom ground becouse of the bank angle all aligned honed, balanced, and squared up with Edelbrock Torker intake, Coles true roller timing chain 11:1 forged pistons, and "C" heads that we're totally reworked and I was putting out 525 HP as well had 400 Turbo manual valve body with 2-speed jet-away transmission from small block 330CI. Tork converter installed into the 400 turbo transmission rewired the switch onto the shifter down for low stall & up for high stall on the converter high stall was 3800 rpm low stall was 2000 rpm with the 5:56:1 posi shifting into second Bourke loose and fish tailed sideways shifting third was about seven feet of rubber with 30" tall street tires...
My Olds 400 engine currently 442 ci, 9.6 to 1 compression, custom lunati roller cam, stock heads, and a tri power intake makes 469 hp and 531 ft-lbs of torque. I wish they would have included the compression ratio. I doubt it was less than 10. Olds does make a great engine.
I had an Edelbrock Performer on my 455, '67 4-4-2 (yes, the original 400 block was stored in the garage), but ot wasn't until I sourced and installed an L69 tri-carb unit that the 60 nover 455 really opened up.
I made more HP. from my 1966. 425 punched out 40 over used mostly factory parts gouged pistons, Coles True Roller Timing Chain, Custom Ground '70 W-30 Stick Grind Camshaft 328 degrees, Reworked the 'C' heads totally blocking off the heat under the intake manifold and filling in the siammized center exhaust ports, I used Oldsmobile HIE Distributor that was Reworked as well, Edelbrock Torker intake manifold, block was squared up, aligned honed, and balanced, as well as oil restrictions and rods ground for oil relief and crank cross drilling and chamfered, the block was also debuted and oil gallies all smooth out so oil would drain back into the pan faster, also used '70 Oldsmobile Tornado 5 quart oil pan. I put out 525 HP
No matter what I build, I always set my ignition timing long before the initial start up! Whenever possible the same goes with the fuel system. Cam break in needs to happen when most guys are trying to figure out why it runs like 💩 or doesn't run at all!
Cam must be pretty mild. When the camera zooms in at the end you see it's only at 4700. You'd think with the hassle they went to they be aiming more like 5500. Needs a different cam and then carbie and headers to suit. But pretty impressive to get 1:1 at that low revs.
2 1/8 headers is WAY overkill for this engine, and would do nothing for horsepower, but would kill torque. My Olds 468 runs in the 9s in the quarter with a set of 2" primary tube headers. A 1" spacer wont do much on a dual plane intake either.
Back in the day I saw a Olds build that used ported stock heads and an Offy port-O-Sonic single plane intake that made 455 hp, without a ton of cam. I’d lean towards that intake, but keep the Edelbrock heads and bigger carb.
Yep. The Offenhauser Port-O-Sonic is a good intake for a fairly stout Olds big block. If you build an engine for more h.p., the Port-O-Sonics bigger brother, the Super-Sonic is a pretty good intake as well if you are running a Dominator carb. My 468 with extremely worked over Edelbrock heads, and a port matched, worked over Super-Sonic with a 1050 Dominator runs 9s in the quarter mile.
They never used to make a performer RPM for the Olds. Just the Performer. Good news is they do now. I think it would pick up 20-25 hp and lose just a bit of torque down low
@@canabox7112 Holley made the "Street Dominator" single plane intake for an Olds a long time ago. Perhaps you had this intake. I'm an old Olds guy also.
How not to break in a cam. Don’t double check that it’s ready to run then shut it off after a few seconds of running after the cam lube has washed off of lobes.
Honestly, I was underwhelmed by the build especially with the aftermarket aluminum heads used. From personal experience, the standard Performer series really aren't much better if at all better than stock. Using a RPM Airgap would have been much better. Also, I'm thinking the wrong cam was chosen for this. You should have been able to easily get 500 HP+ out of it and still be streetable.
A friend had 455 Old in a 1971 Nova. The highway patrol clock him at 120 in the corners and 140 straight aways . The quarter horse could not run him down!!!!! Had about 500 lbs!!!!
Needs more intake and carb. It's hard to kill the torque on one of those. Maybe a little more cam as well and it would easily be over 500 hp and not really lose torque.
Both those carburetors they used where 4 barrel carbs. It's about the cfm it can flow they started with a 750 and it wasn't enough so they had to step up to a bigger cfm carb.
I HAVE BUICK PARK AVENUE ULTRA. IT HAS A SUPERCHARGE BUICK V6. ENGINE. HAS ANYONE DONE A REBUILD ON THIS ENGINE. ARE THEIR ANY PERFORMANCE PARTS FAR IT.
9:12... wipe out the cam and then the plug wires and it’s running like shit , you line up your distributor with the slash you made on disassembly, if it’s not factory marked
@@dennisford2000 Huh? 🤔 You should NEVER "line up a distributor with a mark made during disassembly". That's what a timing light is made for, and is the proper way to time the engine.

You dont polish anything in the intake runners or valve bowls . Yall should know this . Also no catalytic converters ,,, no mufflers ,,,,,,,,,,,,,,,,,,,
or you could pick up a junkyard 6.0, throw in a "stage 2" cam & springs & make just as much power (if not more) for 1/3 the cost. I do love the "retro" big blocks, but it's just so easy to make power with the new motors (Gen 3 Hemi, Coyote, LS/LT).
with alloy heads and modern combustion chambers you can run 11.5;1 comp,, i would have put a $1500 scat crank and rods in it. it would run 500= easy. Hyd Roller cams are useless.
Those factory W-30 Olds big blocks were rated at 510 ft lbs of torque. You didn't do much with torque but match the 455 Buick. HP is up, were really missing out on seeing the comparison between a Factory W-30 matching your build in the same car on the same track. Wonder what the 70 more HP in your build vs. a Factory W-30 would produce in the same car on the same track far as ET under similar conditions? Good results with your build but I expected more. You should have put one of those 4.5'' stroker Olds cranks in it and had a skilled porter re-work the heads. That's what would have impressed me. I'd give your build a C+, an average accomplishment. Think the Stock W-30 was equipped with an 810 CFM Quadra-Jet, I don't remember right off the secondary metering rod factory code, WW/WT maybe? Knew right off, the 750 wouldn't get it. When PSI developed their SCREW-BLOWER many years ago they used a Big Block Olds to drive it on an outdoor test stand to study and develop the PSI's maximum output performance. The 80's.
