Glad you discovered holdener. He has some very good content.

I asked him during the video why on the chassis dyno did the mod 360 make less than the stock engine under 3000 rpm but on the engine dyno it made more than stock under 3000 rpms, He only gave a quick guess of maybe torque converter. So who know :)
