That's a good looking car! Love the paint color choice. Man did that hook up nicely. Congrats to Competition Auto.

The cubic inch on a 5.4 is 330 cubic inch were a 4.6 is 281 cubic inch. We took the 5.4 out of the GT500 and just added Oliver Rods and JE pistons with ratio compression of 8.5.

It is a stock block and crank, we just upgraded the rods and pistons. We did have the heads CNC by FoxLake and upgraded the valve springs, but are still running the stock cams.
