489 vs 742

Yep, Cracked nailed that one. WHOOO! Big power! Nice.

I've seen 8-3/4 handle 750+ fine enuff. But they do surrender after a while. At 1000hp, they will break. The 8-3/4 may handle it if it were all new with the aluminium housing and billet parts and a brace on the tubes etc.... IDK for sure though. I ain't been there myself.
