I don’t know a ton about foreign motors other than surface level stuff like the 2JZ, Wankel, etc. so please forgive my ignorance outside of US motors.
However, in my eyes, it doesn’t get better than the simplicity and easily available power of the SBC, BBC, and 6BT. What are your all time favorites and why?
Coyotes are catching on but still more expensive, but oh man tbatvpowervand and high rpm pull and scream. There was a Cayman with a swapped and modified Coyote that use to run at my track that was a monster. Would eat GT3s alive like they were Yugos and was hilarious hearing that scream come from the car. Plus, whipple’d F150s are fun, brutally fun, love my Platinum that can still tow and rocket away.
Someone else years ago had an old Porsche 917 with an LS7 swap outta C6Z. Lol, was nutty but a handful.
