Today, dollar for dollar, is the 318 faster than the 340 ???

how about this , i give you 2 running engines( not motors no teslas in this thread) , a 318 and a 340 with a 3000.00 pile o cash , which engine would you pick to build with the 3000.00 ?
340 hands down. That's about like asking would I rather have 10 bucks or a 100 buck for free.

P.S. - why do they call motor mounts "motor" mounts??
