Here is a neat one, pump gas 347, but with a baby cam and a good set of heads and intake. First time I have used the TFS Twisted Wedge 11R heads, I am usually an AFR guy, but they did well. Most of the other parts in the engine are pretty cookie cutter.
The day was rough, incredible humidity and 95 degrees. Need to go back to dynoing in the winter
The neat thing is we were looking for 450 HP, and right off the bat it spun 466 HP. Hung in stable to 6600 RPM over 8 pulls or so. Despite a baby roller by most standards, only 216 degrees intake lobe, 54 degrees of overlap it pulled hard. It will be relatively mellow with some chop from behind.
Neat change, we tried a Super Sucker and a poly spacer Brent wanted me to play with. The Super Sucker gained a small amount, but the poly spacer immediately jumped 17 HP and 21 ft lbs. Quite a surprise because we had just used it on a Victor equipped 620 HP 511 and it did well but single digit gains.
