Yes, I was in on that discussion at Carlisle and on the stage with the GM guys. We (GMMG) thought about doing an emission legal 427 but the expense and small cam needed to get it to pass would have you a $25K motor making the same HP as a cylinder head & cam shaft LS1 or LS6. To me, these 427's, for the cost, have to be making 600HP and close to that in TQ. Not sure what GM is doing or thinking about using a 427 in a factory Corvette. They sell it through GM Performance Parts and the Corvette, I think, will get a new motor in the next gen and the LS6 will be standard.

GM did not make a long term casting for the 427 so that is a major reason why it is so expensive. I did talk with Dale in length about doing more dealer built cars for him and his dealership. The Camaro was going to be the first in a line of Dale Earnhardt Specialty vehicles. At the time he was driving the C5R Corvette, the 427 was a mystery motor and no one knew much at all about it. Katech decided to sell it and that is how we got involved in building them. We can thank Charlie Lillard, Bill Porterfield, and Kevin Suydam for pushing me to build these cars with the 427 as an option.

GMMG's name came from two last names - George and Murphy and Motorsports Group. But it is legally listed as GMMG, Inc. Someone said you should tell people that it means "Give Me More Gusto." Well, I need to get back to work . . . we delivered ZL1's # 52 and 40 today and #62 and 46 are going this weekend. So far 39 have been delivered. Most of the rest will go this month.

Matt,

Thanks for the info about the 427 block. It was my understanding that this was the block used by the GM "Vette" race teams. What other engine components make a '427' in your view?

Thanks for your reply.
