Used Blower -- would you buy?

I have a "chance" to buy a used blower ... but it looks like I will have to buy a different blower drive setup in order to use it.


The guy says that it was used on a 427 for one race season.

The cooling system plumbing looks really "hokey" to me, which makes me wonder how well the rest of this thing was put together. Carbs and blower both look like they've been sitting a while ... damp environment ... so the blower will need a good cleaning / inspection, and the carbs will likely need an overhaul, too, right? I imagine the gaskets and seals are all dried up.

He also says that the heads are rectangular-port, so I'm assuming that the intake is as well.

If I DO buy this setup:

1.) Do I need to worry about port mis-match? (from a sealing standpoint -- I'm not overly worried about any performance concerns.)

2.) How much is a guy going to have to spend on a longer snout blower drive set-up?

Advice / opinions would be appreciated.

Thanks,
Don

PS ... this is sort of related to one of my earlier posts ... several months ago.

If he gave me the engine I might take it. Otherwise I wouldn't touch it w/ a 10' pole. From the outside appearance, the inside is junk. Unless you are a motor/blower expert or the seller will let you take it to an expert for a tear-down and check, walk away.

Run away! A new blower from a REPUTABLE vendor like Kuhl, Mooneyham or here in OZ Bob Fisher always works out cheaper than buying junk and rebuilding it.
I wouldn't even buy his engine stand, it just looks nasty.

Also, it looks like a 6/71. On a large port rat wouldn't you rather an 8/71?

It really depends on how much he wants for it. You said the blower setup and it sounds like you are talking the manifold up, right? Not sure about the port situation, you'll have to check into that further. If he want's 200-300, then it's a steal. If he's talking much more than that, then it's ok, but nothing spectacular. Esp if you don't know what the rotors look like and what shape the bearing and case are in. Even used parts for these aren't cheap. If the drive is too short for your application, you don't need a whole new drive setup, just the snout. You can buy another and resell yours and almost break even. You said your not concerned about power output, then minor imperfections on the case and rotors aren't going to hurt you, as long as there is no interference or "bumps" that will hit as the rotors turn. The thing is if it was raced, then it might have teflon tips that may be shot. It also may have been remachined for tight clearences for optimum boost. Not sure how that will perform on the street.

I'm gonna PASS on this deal....

Here is the latest e-mail reply from him.


Hey don,

I took the motor right apart. It had sat outside for awhile and got water inthe block. I was able to saver everything besides the cam and block. I think the block is ok ..but it was already bored 60 over .. you can go lot bigger with these older blocks ..

I was going to make custom brackets so that I could use this short snout system. The pullys I have would be around 14-16PSI so Huge boost !! You could I guess mix and match the exshaust ports but that would be very fruitless as the REc ports are twice as big as the oval ports !!!

...

As stated before .. there is money that needs to go into this stuff to make it road worthy ! I would take 1200-1400 mark to take all my stuff .. even the block ... You can have all that is in the picture ( Minus the stands ha ha )

Rec Port heads are hard to find with open chambers ! These are Chevy Crate motor heads !

The plumbing I was told worked great and I would actually probably run an electric pump on the road as well ! It would be save power and now you can get HUGE despacement pumps for like nothing !! hah a

The carbs are no good. Plus they are crappy carter carbs anyway ... ha ha .. Those would be the first to go !!! This intake has the ports for fuel injection and or NOS jets if needed !! ha ha

I really think you are making the right choice,Johnny

You could probably part that blower out on Ebay and make $5-$600.
