The 340 is the biggest POS V8 Chrysler ever made.
Well, I've said this before and I will repeat it. SB Chrysler and SB Chevy have a LOT in common. Valve arrangement, intake and exhaust port similarities, firing order, distributor placement, general size and shape.
You better be in a GOOD state of tune if you were back in 1970 and pulled next to a real LT-1 Camaro. You better HOPE like hell he AIN'T in a good state of tune. The fact is, yes, the little 340 cars whooped up on cars with bigger engines. But there were cars out there that the 340 was not gonna hang with.
The Hurst SC Rambler comes to mind. You probably don't wanna feck with a first generation 396 Camaro. The 340 was a badass combo in an A body, but there were certainly cars that could mop the floor with them.
