Got this from another board..Finally...after more than five years of effort and countless hours and dollars...it's alive...! :D

The 601-cubic inch Pontiac of my dreams has been tuned and tested at Westech in SoCal and is being boxed up for shipment to me here in MN.

The engine consists of an Indian Adventures aftermarket tall-deck Pontiac block with a 4.375-inch bore and a 5-inch stroke. The crank is a custom Moldex billet unit created for this engine. The rods are Oliver 7.250-inch H-beam units. The main bearing caps are billet. All the engine hardware is ARP.

Butler Performance in Leoma, TN, is responsible for getting it all together. They did the homework and worked hard to develop a package that would make good power and last long-term. The trickest parts are the cylinder heads, which Butler pioneered to feed the large-displacement Pontiacs. The pushrod holes normally found outboard of the intake ports limit how wide the ports can be, so Butler eliminates them and incorporates the pushrod hole into the intake port. But, the pushrod has to go somewhere, so a combination of offset roller lifters (by Crower) and offset shaft-mounted rocker arms (by T&D) move the pushrods over far enough to accommodate the huge (by Pontiac standards) intake ports. They start with Edelbrock Pontiac aluminum heads and these have proven to be effective in feeding big-inch/big power Pontiac engines.

The cam is a Comp solid roller. Lift is barely over .700.

Final assembly was handled by my pal Andy at AllPontiac. I hated to leave this behind when I moved cross-country, but I was assured it was in good hands.

The final numbers from the dyno showed 738 peak hp. I'll have complete dyno info on this soon, but I just got the phone call and this is all I can say right now. There's lots of torque...heh heh...and it'll run forever at low rpm levels while making big power.

I am very satisfied with it at this point. I know it will be further fine-tuned when it gets here and meets its new best friend...the big blue bottle! The 9.75:1 compression was intended to work well on pump gas and additional power could be had with a programmable nitrous setup. I intend to add between 300-400 more horses with the juice. I have two 12.5 lb bottles that will be in the car at all times.

I fully intend to see 1,000 rear wheel horsepower at full song.

With a pump gas Pontiac...on the street.

I'm stoked!
My 87-octane 383 project worked out better than expected...545hp on 87-octane! See the story on that one here:

My 601ci Pontiac met the goal...738 hp before nitrous on 91-octane pump gas...

...next - The mighty Buick Straight 8!!!

Maybe I should finish some of the cars these engines are intended for. That might be a good idea. At least the 383 is in a car and running...

~Scotch~

P.S.- "What the hell are you going to do with it, Scotch?"

The engine will live in a '65 Pontiac LeMans that will be run on the street, strip, road course, and in open road competitions like the Silver State Classic Challenge. You can see a rendering of the car here:

I'm hoping it'll break 200 mph one day.
Trans is a 4L80-E, rear axle is a Ford 9. Wheels are 18s and 17s. Brakes are 12s and 13s. Front fenders, hood, bumpers, and decklid are 'glass. It will be caged (not shown in rendering).


Thought it was cool...

[PooterWS6]

So how many mortgages did he take out?

[OrangeChevyII]

Thats a huge stroke......dayum!

[MattB]

Is that the dude on the Hamb? If so, he's been building that motor for at least the past few years. It's good to finally see it completed and on a dyno!

He sounds excited. :D

I believe this is the thread with the info about the buildup:

http://www.pontiaczone.com/forum/showthread.php?t=12768

Those edels are "wide ports" which will get about 370cfm. New tiger heads will get 400cfm out of the box before porting.

My guess is that at a bare minimum he's got $15k into that engine and probably way more with the butlers and andy mitchell involved.

Pontiac community tends to focus on N/A power and CI and hasn't really adopted power adders yet. Probably because nitrous is the only readily available power adder for a pontiac at the moment, although vortech is working on some kind of a kit. Also, the cost of going beyond stock cranks and blocks is pretty stiff.

I'm working on a turbo setup myself at the moment; just waiting for more benjamins to appear in my wallet.

Edit: way, way more than $15k

[turbostang]

man.. I wonder why he built such an extravogant (sp?) motor for that little power output? Not to mention a BIG displacement motor that he intends on using for the Silver State stuff... but hey, NO ONE else has some shit like that!!

[mikeb]

I think he could get a lot more power with better heads and a bump in CR. Those edels are like E7's on a 408. Of course, then he couldn't run 93 octane.

hey man people pick their own poison he'll be getting passed by turboed sbf... lol

but that is a clean ass engine.

I think it is cool for a pump gas motor but I don't see why he is going to run n2o(especially 300-400 shot). It kind of takes the dependability part out of the picture IMO. He should have went turbo and made more power without being so hard on the motor. Still cool though. Nice find.

[Futurama]

for that much money and 601CI, im not impressed at all. 1/4 the money you could build a LS1 based chevy that would beat those numbers, hell for a little more you could build a ford to beat those numbers. i like pontiacs, but that is just rediculous.

[Lason]

DAYUM! For that kinda cash I would have thought a twin turbo 455 would have been cool and probably made alot more power to him!

There is a guy that built a TT 455 using a stock block, stock crank, and factory ported iron heads that runs in the 9's in a 1980 bird. IMO he's past the hairy edge making that kind of power on a factory nodular iron crank :eek:

I agree with everyone else, it's a pile of money for not a lot of performance. Has nice "wow" factor though.

740HP (and probably 850ish TQ) on regular unleaded, all motor, with a small cam is wimpy? :confused:

LOL at getting a Ford to do that with less exotic pieces. :rolleyes:

No, that kinda power for $15k is wimpy

[Futurama]

exactly, i wouldnt give a shit it it was 600 cubic inches of renault, its just not impressive. looking at the bill, im surprised its not andrews motor.

[46Tbird]

Tough crowd. I'd LOVE to see an LS1 that can pull that for $4K, including buying the engine.

I think it is impressive for a pump gas n/a motor. I just think he would have been able to make alot more power by adding a turbo instead of using n2o. The turbo would still be very streetable and easier on the motor.

I would like to see a LS1 make that kind of power(not only peak power but area under the curve as well) with 9.75:1 compression. Also, people have to take in acount the block alone cost him about $3300.00 and the heads cost about $4k. It doesn't have the cheap cost like a Chevy.

Yeah I dont think we could see a LS1 put down numbers like that for $4k. Although some low compression pistons and a JY turbo setup on a LS1 MIGHT do it! But that is assuming you already had the LS1 and $4k for mods alone.

**EDIT** Btw, I never said the LS1 would live long :D

We're talking n/a on pump gas though.
