1969 GTO the GRUDGE PROJECT // I bought the got from MR VENGEANCE !!!!

[CoryBuiceAKASkuzzy]

I got this gto five years ago .. It has a 1973 400 with 4x heads ,,, the 2:11 1:66 valves TCI 3 speed transmission ... and 8:4:1 compression . I started taking the car apart to do MAJOR RUST REPAIR ,, I bought a donor car and i am replacing the upper cowel and dash,, floors, trunk , and tail panels ... the rear package trey ,,, transmission is being swapped for a TKO 5 speed . I plan to keep the 4x heads i have which have the 98cc combustion chambers. I am putting in a eagle 428 stroker crank with the 3inch mains so it will fit in the 400 ,, and using the 6.8 BBC rods with flat tops forged rods as well . This set up should put me at 9:4:1 compression ratio ///




not sure how Much horse power or torque i will have but i am guessing 420-430 hp 500 is torque ??


work should be competed in a few months ....

Performanceyears.com forum is your best resource for parts, info, engine builds and all things Pontiac. Then you have this place, which is great for making that old Pontiac drive and handle like a new car! I'm pretty active on both. Welcome!

[CoryBuiceAKASkuzzy]

Thank you for the welcome. I'm so glad after five years to finally get into this thing now that I'm 25 a little older and a little more stable money wise .. looking at $1,400- $1,700 for the motor and $2,000 for the metal work .. talk about budget POWER right

[Nicks67GTO]

Oh and be ready for a bombardment of suggestions that you should LS the car for 100 different reasons......

You really don't need much to make the Poncho stuff run hard. I think your 430hp/500tq expectations are spot on for a mild performance 428. There's more in there for you if you want to do a little bowl and port work on the 4X heads. I'm not sure how familiar you are with Pontiac stuff but ill throw this out there anyhow..... Do not pitch your cast iron intake, HEI or quadrajet. They are all very workable, the stock Pontiac intake is a really good design that is just as good good if not better then most aftermarket intakes in milder applications and the Quadrajet is a great carb if you have a little patience.

[CoryBuiceAKASkuzzy]

I will never and i mean NEVER run anything in THIS pontiac but a real deal pontiac motor ,,, they can keep there LS's i do not have a cast iron intake i have 3 eddy performer intakes in all one is on the car ,, which i hear is a nice intake ... I do plan to port the heads both the intake and exhaust ports and runners ,, LUCKY FOR ME A PONTIAC OWNER my bowels come from the factory pre machined so i just have to do a polish job there for not losing any cc's and being able to keep my 9-4-1 compression .,,,, one day when i have more cash i will switch to the 85cc eddy heads .. I DO LOVE suggestion though!

[CoryBuiceAKASkuzzy]

are quads better than hollys ? i have a eddy carb on there and it sucks ..

Nothing wrong with budget power at all! I would be shocked if you can get then engine done for $1700 though. If you check my build thread i'm running a scuzzy old 455 I got on craigslist for dirt cheap. A little elbow grease, paint, gaskets, rear main seal, rebuild Qjet, and an HEI and the engine looks like a million bucks and runs just as good. It starts and runs very reliably and has enough power to boil the tires anytime I want. That's good enough for now!

[CoryBuiceAKASkuzzy]

well i added all the cost of the parts up , and i come to $1,400 for the crank , gaskets , rods , pistons , bearings , i factored in a another $300 for parts that i might need ..ill post what it costs all said and done so other people will have an idea ..

[Nicks67GTO]

I bought a 73 Quadrajet core for $25 bucks locally. I read Cliff Ruggles book on how to modify them.

They are not very hard to mod in mild applications, if you're mechanically inclined and take your time. I then called him up, tell him my combo and he has me order a few parts and a rebuild kit and Iv'e got $100 bucks in a carb that doesn't mind ethanol and it runs like a top. Choke works great, no bog, no hesitation, no BS. It just runs pretty darn good.

The performer is ok. I run one because that's what was on my car but there are much better intakes, including a stock iron intake.

Be careful on the port work. There is a book out there by Jim Hand and he goes over what to do and what not do do on Pontiac porting. Pete McCarthy also has a video you can order that goes over everything you need to know before you start cutting on old Pontiac iron heads.

Well since you said you like suggestions I'm going to strongly suggest you opt for the one piece pan gasket and modern Viton rear main seal from BOP Enginering. I used these when I did my gaskets and now I don't leak oil. That's well worth the few extra bucks right there.

[CoryBuiceAKASkuzzy]

Will my intake kill my hp aspirations ?? :((( and will a holly do ok out of the box ?? i plan to use an aluminum intake only because i have one and weight ... i could sell all three and get a better aluminum intake , what kind of aluminum intake would you recommend ? I do plan to go jim hands route .

[CoryBuiceAKASkuzzy]

One piece pan gasket ? i thought they were all one piece ? ! i was looking at like a felpro engine gasket kit from summit .. is that not good ? if not i will deff go with your selection .

Your best bet for engine build info is over at Performanceyears.com forum. Those guys have all kinds of fool proof combos that are dyno tested and proven to work. Lots of real Pontiac specific engine builders over there. I'm going to bet they tell you to sell the performers and go with the performer RPM or a stock intake but don't quote me on that. I'm still running one because its what came on my engine and the car runs great right now, so i'm not going to mess with it for the time being.

No they are not all one piece. Most of the cheap ones are 4 piece I think and they leak. Call Wade @ BOP engineering and talk to him about the viton rear seal and the 1 piece pan gasket. These are trouble areas for Pontiacs and his stuff is the solution IMO.
