[6pack] Performance Research Industries

[Dave]

I would suspect that triple webers and a mild (or wild) cam will get you 
most of that way for less money.  I have the ZS triple carbs, mild cam, 
lightened flywheel, shaved, polished, ported head, decked block, 
rebuilt/recurved dizzy, petronix, and a few other bits.  I was dyno'd about 
100 at the wheels.

don't forget to upgrade the suspension and especially the brakes!

Yah they want just about $8,000 for the engine I want. I am torn between
supercharging and this. The problem I have is that I can't seem to find a
definitive "formula" to put together my own engine with the Moss
supercharger, i.e. which cam to use, compression ratio, porting, header,
etc. If there was a book on the matter I'd buy it (I do have the Kastner
gem). I have a low-mileage rebuild with good compression and a 10.1:1 head
currently so the head would have to go if I supercharged it. I have no
problem tearing into it if I knew where I was going with it. I don't want to
just hang parts on the thing as that leads to disappointment.


Thanks for your help,



Brian

If your motor is in good shape (compression, head, etc.) it would probably
be cheaper and easier to bolt on a Moss Supercharger kit. The blower will
make more a difference at the speeds we normally drive. If you're going
autocross or race that may not be the case. Building up a motor without
forced induction can be rather expen$ive.

I had a Moss kit on my old 72 Six. It really pulled hard!

Does anyone on the net have first-hand experience working with Performance
Research Industries (PRI) out of Oregon? They have some natural aspirated -6
engine build-ups that look very interesting and are indicating upwards of
160HP.

Thanks,

Brian
