70" 340 vs 72" 340 specs please

Funny how every goob out there thinks mopar is limited by it aftermarket choices.When in fact the LA and the big blocks were as close to a racing motor that you could get back in the day,stock.And the "real" reason chevy has so many aftermarket choices is because they were not up to par(Mopar that is)stock:yawinkle:

All those hp examples have giving me alot of ammo aginst my dad,who owns a 69 mustang mach 1 with a 390.I think hes nervous,Since I put my 6 pack on my dart he has gotten him a 6 pack from the early 60's to pit on his mustang :D
