Stock cam 346 making 430rwhp with poorly done 241 castings... 
Those numbers could only come from around 11.5:1 compression on a number happy dyno with the operator using every dyno trick in the book. I hope the GTO owner is happy with his dyno sheet, because the track performance will be disappointing if he expects it to run like a 430rwhp GTO should - trapping MINIMUM 119-120.

this dyno reads the same as another one in same town.
Tracks times forthcoming. Looking forward to the results as well.
