Really enjoyed the video thanks for posting! Makes me rethink running a 5.2 magnum in my Dart and stepping up to a 5.7 Hemi instead.
OOTB the cylinder head is 80-120 cfm better. Most of the same difficulty to install also.
Agree on the head flow, not on the rest as I have already done LA to Magnum swap on 2 other cars. Very, very easy and fairly inexpensive to install a magnum 5.2 or 5.9 in an a-body. Such a huge advantage over LA I got rid of all my old LA hardware.
I'll do the numbers again, perhaps some of the required swap hardware has come down in price and the numbers look more feasible. Problem finding good hemi engines too. $3000 for junk with 100,000+ miles.
I've seen complete 5.7 car motors for $500-1700 down here. The expensive one even had a 5 speed auto attached.
The headers and the EFI are expensive, but worth it.
