Are there any differences between years 05 through 10 WAP blocks that came in 3v GT cars? Asking because I keep reading on here that these blocks are good to 1000k plus hp, however, in Sean Hylands book he suggests not making more than 600 hp with these blocks (up to 05, I think he said). Curious if there's a difference, and why he would say that, if everyone is having good experiences with these blocks over 600 hp.
Thanks
