It will run on pump gas. The big cam will lower dynamic compression to streetable values. 11:1 isn't too high at all. I guess it might give you problems if you used it to pull an 8000 pound trailer through the mountains.

 

can't pull a trailler with my stall anyway . i talked to the guy, he says he got like 14-15 highway and about 10-11 street. and he only has to adjust the valve lash about every 5,000 miles. So sounds decent enough
