No kidding huh? Wonder why people are charging so much for a piece of cast aluminum.

Id go S475 unless wanting over 850 RWHP then go S480. If wanting to push 80 to limits go with the race cover. 80 gains more than 75 with race cover because it taxes cover more but unless pushing turbo I doubt you will notice.
