Are 340’s rare
All this comparison of 340's and 408's....well I have one of each. Two TOTALLY different animals.
I've had my 71 Demon 340 since 1984. I tell folks the car is a "sheep in wolf's clothing" as the Green Go paint and flat black hood and twin scoops and black stripes scream performance car. But it is not. It is as stock as I could make it other than it has the old purple shaft "hemi-grind" cam in it. It is choked down big-time by the exhaust pipe where it bolts to the manifolds. But I wouldn't trade it as it is supposed to be a 340 car and it is. Just a sweet little car with the proper 340 in it.
The avatar car was birthed in 2019-2020 with its 408. That is one FUN engine. Yep, massive torque and not so much power as it only has Eddie RPM heads with minor bowl blending. But I've said this many times - it's like a young male teenager that just wants to run, run, run. "Please stand on the loud pedal" is what it says every time you're in the car! Oh, it's been to 7500 rpm a few times but not by plan (oops, that would be my fault). But generally it's happiest shifting at 6200 rpm and trapping at about the same rpm. With mid-250's cam duration, if I built it again it would be mid-260's as that 4" arm eats duration. Does it rev fast? Dunno - nothing to compare it to. But it's a barrel of fun for sure as that 6200 point comes up pretty darn quickly. [email protected] PB so far for this "tractor" motor and its non-ported Super Victor intake.
I can't be partial to either one as they are such different things. I enjoy both of them. But for a street/strip car, the fun factor of all that torque from the 408 is hard to beat. (Now if I can just coax a 10.9x from this tractor...!!)
They both got to go to a cruise today. And my wife decided she wanted to drive/roll in with the avatar car. She voted with her right foot!
