I think the reason you don't see many '73, '74 340 Challengers is the HP rating. The '73 is NHRA rated at 293 and the '74 is at 305. The later F body cars are rated a little less (289) and have 20 more cubic inches with the same cam, heads and compression ratio. No brainer in my opinion. Jim

BTW Very nice looking Challenger Jason!
