Re: Nitrogen Enbrittlement (acid manifold porting)

[RMEbstein@aol.com]

I had a stock aluminum GM big block intake manifold done by Extrude Hone. The 
cost was $425 and it took somewhere around 6 weeks to get it done. I had my 
engine dyno'ed and it helped a lot.

However, I probably will never do it again, since the price/HP ratio is very 
small and the port sizes remained about the same.
