1972 Demon 340 engine mods

Yes the heads are aluminum Edelbrock Performer RPM ported, I posted the numbers earlier. Also intake is matched with the heads. All set with rockers was bought as a really nice package deal.

Gas is the same, just different way of measuring. Numbers look better 95 vs 91 and 98 vs 93 but it’s all the same thing more less.

I do this stuff for free, Demon owner is a younger guy that bought his first Mopar not long ago. I’m just trying to help him out and also protect nice car from getting intro wrong hands. Tons of hacks here that don’t think what they are doing.
I prefer to ask you guys as this forum really made me learn a ton.

Money part is not easy, you see all the stuff costs us almost double to what you pay when we add shipping and customs. This makes things a bit less accessible. We constantly hunt good deals and this set of heads with rockers was just that.
Stroker build is a no go. If we had better access to stuff at USA prices I’d probably be done with building 408 for him with 4 speed or some aftermarket box by now. Sadly it’s not the case.
I want to make it work well and look good also.
New heads are 63cc (I checked with plugs in) so there will be a few extra hp from compression bump also.
Will update tomorrow about what psi it cranks and heads will be off a week later.
