Making Port Style Injection bye bye Webers

[ECMnut at aol.com]

Hi Jeremy, 
there is a product called Moroso A/B Poxy, or Racer-Poxy 
that may be useful to you in making your injector bosses.  
It comes in two sticks.  You mix 50/50 and then shape it
like clay.  In 24 hours, it's rock hard and ready to machine.
 I've used it to add material where needed in the
intake ports.  You can grind it, drill it, tap it, etc..  I ordered
 it from Summit racing for around $25 US.  It stands up to race 
gas and 220 F temps..   NHRA Super Stock racers use
it pretty extensively to reshape intake ports.   Their rules 
require the port to measure out to the same volume as the 
factory port, regardless of shape.. .  So they fill & grind" till 
the flow bench wears out...   If someone knows
of a *generic equivilent* material, I'd love to learn about it.
