Damn dude... Next time you need something like that bring it over and I'll Tig it for you. I'm right behind IWSI on W. 11th.

Great #s by the way. Did you assemble the short block?



I did assemble the engine and came up with the combo myself, but with plenty of research and questions.
Springers did the machine work on the block.

Cab, yes it’s a super flow but that’s all I can tell you. I realize that a dyno is just a tuning tool. But I can promise you the numbers are very real off this dyno. And usually disappointing.


The 80 degree air temp doesn't seem correct so that is inflating the numbers a little bit. This time of year the air temp is in the 40's or 50's. He must have his temp gauge mounted somewhere in a heated room since it doesn't vary during the pull. Usually the dyno room is well ventilated so during a pull the air temp will drop down to be close to the outside temp since so much fresh air is pulled in.
