I,m in the process of putting together my engine for my new race car and i have a few questions on bolt/stud selection. I will be making atleast 1200hp with an iron block and i need to know if anyone has run any A-1 technologies 7/16 bolts. I've been told from some very good sources that the 7/16 bolt from A-1 is srtonger and better than running the ARP 1/2 studs. If anyone has some info for me and can help out it'd be great. The people i've talked to that are useing A-1 stuff are NASCAR team members for DEI and Yates and a few Top Fuel NHRA guys, but i've only heard of a handfull of guys using them in there LSX based motors, and they don't have any problems lifting heads yet.
