I knew Carlos personally and he told me when chevy or Ford set a record they would send him a car and say beat that record!!!
He did my engine in the 80s for my GTX that was running 10.40s,which was amazing back then !!!
This guy was a genius with head flow!!! And didn't get get recognition he deserved and I'm 99% sure Honkin Hemi was his originally, I seen at his shop and he told me this story. He started losing his eye sight and had to stop building!!!!
My 2 cents
