Actually I thought the 440's were in plenty of recent kits, and really, can you see the difference between a B and an RB block in 1/25? I would think the guys wanting a 318 can build one up from the AMT Duster 340 without a lot of work. I'm 59 years old and lived through the tail end of the muscle car era and several of my friends had Hemi cars, they were out there.
