509395 should be the casting code but I can't validate it in the list of valid Pontiac blocks. It may also be the last digits of the VIN for the car it was installed in.

15H indicates that this is a 1963 389 267 HP engine installed a full size Pontiac with an automatic transmission and 2-barrel carb.

Great info Frosty ! that engine number doesnt match up with Dwights vin, but the year does ! 

and really i am not building a matching numbers car, so it doesnt matter at all, 

what i am trying is use as much Pontiac in my build as i can. and at least, gm items like the vette suspension 

it would be easy for me to stick a ls engine out of a holden, they are everywhere but whats the fun in that !

These are my boys right here!!!   BDS   They cut down and welded on a blower plate to my intake to make it happen.  Then worked out vbelt and blower pully's N spacers.  Contact them, as I can't find anything for a 389.

Thank you justA !

i was having no luck finding anything for a 389 too !!

Butler Performance has a ProCharger and TorqStorm set-ups for Pontiac engines

I'm with Frosty bro. If I was rebuilding my engine tomorrow, I'd be reaching out to Butler.

Butler is the go to for sure, on how to build the internals, but a Procharger is NOT what Chris is looking for.  Looking to put together an on the manifold supercharger and keep it under the hood.  B&M had the perfect solution and it looks like Whipple has the idea he would like to run with and keep the hood intact.  Holley bought out B&M.  If BDS (blower) will build a manifold for Chris (as they did for me back in the day)  they might be able to keep it under the hood.  Pro Charger or a system like it might have to be a consideration for the $$$ part if nothing else.

JustA is dead right ! i dont want that blob sticking out the side of the motor( procharger) the whipple blower looks looks wayyyy sexer ! or even the harrop blower !

You can see where BDS cut the top off my intake and welded on the blower mount. Notice the spring loaded blowby plate in case of backfires you don't have the spectacular launch of the blower  AKA NHRA....  Maybe you can contact some of these other supercharger manufactures about doing the same for you.  B&M sells a kit for Chev small block maybe you could cut that one and weld it on a Pontiac aluminum intake.  We can all keep an eye out for solutions, it's gonna be a long time before you finish the body, chassi, interior and start worrying about your engine upgrades.

Right now I am not aware of any low profile Whipple/Eaton style supercharger on a Pontiac engine. So this maybe a custom job.

Thats really cool Justa!

thanks Frosty, something i have considered is to build a manifold from scratch. 

[Frosty]

Perhaps you can adapt one of these BDS Pontiac intake manifolds to a Whipple or Easton supercharger by building some sort of adaptor plate.

Exactly what I'm talkin about.  The base for the B&M could be welded right to this or ANY manufactures aluminum intake.  Watch the swap meets.

[64 kiwi boni]

Wow that could work !!! 
and it looks like I could drill each port and weld in a sleeve for each injector too !!

Kiwi, not enough time to get in to it right now but a couple quick things! The 3800 that is in the Grand Prix (1997-2003) is a low profile supercharger that uses a thin lower manifold. So I would tell you that with the right mods you can do it. Also, those finned valve covers are somewhat rare & renewable.

Last Indian , I am wayyyy away from building the engine for the 57 

but would you mind if I get your guidance when I am closer ? 
even if I buy the blower and a manifold like frosty has shown and you could help me ? 
my thought is to port inject the motor, and have a stand alone ecu to control it. That’s why I built that little cortina, so I learnt how to make a custom system 

that motor has itb throttle bodies 

but I want to use a whipple or similar justA because I want the look of a hellcat like blower and that sound !!! 
tucked down neat and tidy in the valley, not sticking out the side of the motor !!! 

with a single throttle body and tps. Then I can make a cold air intake that looks sexy under the hood in the 57… I have some ideas how to plumb that too ! 

[64 kiwi boni]

My inspiration comes from this bloody sexy plumb crazy hellcat that I justA sooo I enjoy driving ! 
i have a stock 707 Hp and it’s complete street drivable !! 
the super charger in her is tucked down in the valley and has air con cooling the incoming air . And to look at it under the hood it looks clean !

that's what I want for the Pontiac engine … I think it can be done ! 
it’s a challenge yes ! But why not have a go ! 

[64 kiwi boni]

Question for you guys . Are all Pontiac v8 the same port configuration ? As in , when I am looking for intake manifolds and exhaust manifolds for the 389 heads . Are other sizes the same ports and bolt ups ? 
I fitted the long branch cast iron headers to my 64 389 without even thinking about if they would fit !

Hi 64 Kiwi Boni.

wow, great web site thank you bob 

[64 kiwi boni]

this is what i have found, that has port injection bosses, 

https://www.edelbrock.com/super-victor-efi-pontiac-intake-manifold-for-4150-series-throttle-29575.html

then a weiand blower or simliar, kind of like the whipple unit better but it needs to have a base that i can make a plate and weld it to the manifold

https://www.holley.com/products/engine/forced_induction/superchargers/superchargers/parts/6520-1

i have spent a couple of hours just hunting but i still cant find and one who makes a port injection supercharger kit for a pontiac engine. so i guess i will justA build one ! 

i already know how to set up a stand alone engine control unit, lernt all that with the cortina/duratec build.

but adding a roots style blower into the intake manifold is clearly something the after market isn't doing for Pontiacs, there is heaps for chevs fors mopars but not our babies !!

Yeah your asking why i am bothering to go down this track !!! and yes there is lots of easy ways to make more hp out of a pontiac. i justa like the idea of look and sound that the roots style blower will make. and it will suit my 57 classic built with out it sticking out the hood, or driving like a drag car.

my whole plan is around drivability with this car, but with power to shred tires on demand along with the wurrrrr of that blower !!!

foot note here too !

the reason i am working out my engine plan is i want to front foot my costs. once i have the plan in place, i will start groveling to the boss.... this is next year !! and then the year after that, followed by the one after that..... and i know she wants to travel next year... soooo .... happy wife happy..... urrrr um... i forget ! i am old !!! 

[64 kiwi boni]

I have spent the weekend working from the beach 

and got home Sunday afternoon 

and had just enough time to lift the 389 off the Ram , build a roller frame to move it around the workshop … note to frosty !!

another use of a 2 poster mate !! Lifting stuff !!!

I've refered to Wallace Racing for years. Great and reliable source of engine info.

Kiwi - be a little more specific. Generally speaking all 326-455 Pontiac V8 heads are essentially the same head configuration. Exhaust ports can be round or D-shaped depending on the head casting number. All share the same bolt pattern and water passages. Some rare heads might be missing a bolt on the #1/#8 exhaust port, but if can be drilled and tapped if it is missing. So generally speaking a 400/455 head should bolt to your 389.

thank you Mate, that very much answers my question when hunting for intake manifolds
