What goodies do I need to build a Fast slant 6

Steve Dulcich (Roadkill Garage) put together a hot supercharged slant that made around 300hp but that blower kit was 3 grand at least! They ran it N/A once and it made ~220hp at the crank. He ported the head, shaved quite a bit off and put a good cam in it, then topped it with a 4 barrel. So that's about as good as it gets as far as I have seen.

If I ever find a spare slant I'm going to look around at other OHC cylinder heads that might fit...
Hi Loggato
So I’m guessing he’s on this forum then? And on this forum is it possible to pm other members? I’m only new so still trying to work me way around and figure out what’s available on here.
I’ve looked on the Aussie speed shop website and noticed how expensive a supercharger is there approximately 8-9k and that’s obviously without a good carby setup the a good exhaust and a nice engine build so going to be looking at around 15k to the hp I’m looking at so that’s a hell of a lot of cash for what’s really a basic engine in the way of technology wise.
If only they had came out with a 265 in them as it’s reasonably easy to get 200wrhp without spending a heap of cash.
