Project Blown 305

Just remember that the V12 has different intake manifolds due to spacing and they will not interchange with the V6

That is an issue with the magnum heads. Correct?

No That is an issue regardless of heads You simply can't use V6 intake manifolds on the V12 nor can you use V12 intake manifolds on the V6.

Found a blower off a 6-71.....might be to small though.

Nice! I'm hoping my neighbor will sell me the 8v71 he has for a reasonable priced that one was pretty expensive.

If the intake is close I wouldn't mind modifying it to work I'm just curious what it looks like.

Thanks to Atomman I now am a little bit closer to getting this project off the ground!
Now I just have to wait for it to arrive and figure out which blower I need!

Very excited!

That looks fantastic

Thank you, now having compared to the 6v92 my neighbor has it looks like I'm going to need an 8v71 or 8-71 minimum.

They sell adapter plates for the V style on a normal flange so I may get that since i can avoid trying to drill the angled holes myself and I can drill for a convention 8-71 and be able to swap between em.

We shall see, I'd like to not have too terribly much into making a blower work since you can buy them new/used with a lot of the parts I'd need out of the box.

So here's my plan.

I found a few eBay sellers with blower parts for very reasonable prices

I'll need the blower front cover, the blower rear cover, the snout, the pulleys (which I'll probably buy two to start mock up with them change later) and the adapter to go to the 8v71.
So far I've purchased the adapter, this is already drilled for the angled bolts and includes studs gaskets etc.
I mocked up the stuff a bit.
I'm contemplating cutting off the whole water pump setup to save space and run an external pump, it wouldn't be hard as the pump is cast into the front cover and I'd just need two block off plates to cover the holes and put AN fittings up to them or a spot to clamp a hose. This would also allow me to run only the crank pulley for the alternator (too bad I didn't get the magneto lol)

Turns out they sell new old stock 8v92 blowers for about 600 so I'm hoping that will bolt up the same way the 8v71 does as far as I can tell the engines underneath are the real variance not the blower itself.

Here's the parts needed:
