Yes, this is my M1 intake that I had bungs welded in for my EFI conversion to my 408. I did a bunch of port work on this intake and wanted to reuse it instead of buying the Edelbrock intake that already has the injector holes drilled. Hindsight, I should have just bought the new intake. Apparently the aluminum the M1 is made out of is ****. They had a hard time getting a good weld. I was expecting it to cost about $100-$150, but they hit me with $320. Needless to say I was pissed since the Edelbrock cost $370. So now I have a $500 M1 if you consider the cost to buy a new one. If anyone is thinking of doing this, suck it up and spend the $375 on the E-brock.
