I just finished a 347 for a local 7.50 1/8th mile drag racer. He runs a Fox body Mustang and B2 Motorsports is sponsoring him.
This is more motor than what he needed, but he thought he may want to run a lower ET class later on.
This little fella with AFR 185cc heads, a Comp solid roller cam, Super Victor intake, 10.5:1 compression, and a Demon 650 made 482hp @ 6500 and 430 lb-ft of torque. It was dyno tuned with the 650, but he has plans to add a 750 soon.

Should be a real fun little motor for him.
