They still help Allen some. To my knowledge, Allen is one of the few that doesn't run into part replacement issues the same way newer teams do whether that is due to their current inventory or something else I don't know. I'm curious if they are still having the same issues as before with the engine. From hearing from people that have had experience with both, they always mentioned that the margin for error with the hemi engine was small because the power band was much narrower than that of gm. It will be interesting to see what new designs may be released and how the development of that newer hemi head with the IEIEIEIE valve layout goes. I hope Allen and Wilson can find some things this winter.
