A Phase IV 427 or what we called a SR427. It was our first attempt at building a solid roller 427 race engine. It required a lot of special parts internally and externally. Ext. it required new valve covers which were specially cut out of billet to handle the taller rockers and has ZL1#69 engraved in them, as was the intake that our engine shop and Wilson Manifolds worked together to make this one off custome intake for this motor. $5000 for the intake and $1000 for the valve covers. The custom throttle body hopefully will be here this week so we can test it for the final time. It is making 585HP to the rear wheels with a stock LS1 throttle body, that is just under 700HP to the flywheel. Grumpy himself was involved with this project and said that he was interested in driving the car when it is finished. He signed the car and a contract with GMMG on the car. What a great guy . . .
