Does anyone have info on the strength of the tubular LCA like Sphn's versus the rectangular versions offered by Hotchkis and Edelbrock?

Also what is the weight difference if any?

I have the Edelbrock version now and would consider switching to the tubular if the strength was the same and the weight was different.

 

Our tubular LCAs are 7 lbs. for the pair. (3.5# each)

Have some 8 second customers that haven't hurt them. The LCAs actually don't see alot of abuse, they take a compression (end to end) load. The torque arm takes all the major abuse.
