They are nice. KimI don't know squat about speedmaster big block heads but they always look like a pretty good head to me.

as in they look nice or they actually perform. I just think they look nice.They are nice. Kim
I don't understand why the B/RB platform, other than body fit, is not an advantageous platform out of the box. Wider bore spacing implies more room for valves, and the ports should be simply better I could be wrong about all of this.
Bingo! As an aside, the machine shop I use now wants an enormous price for a full rebuild. They told me it will now take 4 months and $3500 labor + I supply parts. That puts me into the crate engine cost territory. Just taking a block and heads to them to see what is needed would sting the budget before the project ever got off the ground.Depends on what the car is set up for currently. If you have to go changing k-frame, trans/bellhousing, driveshaft, exhaust, etc., then your budget is out the window. Build whatever the car is set up for.
I like all 4 of those vehicles !!Kind of a funny comparison.....
THIS car has a 360:

THIS one has a 383:

The Dart has stock 8.2 compression, exhaust manifolds, 2 1/4" exhaust, an MP 280/474 cam, Weiand intake and a Holley 600. 4.10 SG.
The Charger has 9.2 compression, headers, 2 1/4" exhaust, an MP 280/474 cam, Edelbrock Performer RPM intake and a Holley 750. 3.91 SG.
The Dart has more low end torque than the Charger. It feels quicker out of the hole but the Charger will catch up and make up for it when the rpms climb. I attribute the difference to the difference in weight and the stroke. The lighter Dart has more stroke so it gets moving faster initially. A higher stall converter and swap the gears car to car and the Charger would pull from a dig much better.

I think this comparison is pretty much personal preference , I understand the benefits of the 383 but you take the longer stroke of the 360 combined with a good set of light flat tops an appropriate hydraulic roller or solid lift camshaft heck even a good hydraulic camshaft and air gap with both motors using a stock head whatever you choose I have to say advantage 360.
Absolutely large bore can make torque just like stroke so 383 versus 360 that's about a wash as far as a 906 being Superior to a small Valve j okay okay but a 202 X or j will outflow a 906 so what's up now! LOLStroke is only one part of the equation the other is piston surface larger piston will have more psi pushing it down, so a 4" bore is gonna have a lot less pressure applied across the piston than a 4.25" so yes 360's 3.58" stroke is gonna have more multiplying effect than a 3.38" stroke but is gonna have less psi to multiply in the first place. It cid that matters not really how it's made for the most part when it comes to torque. Plus a 906 head gonna smoke a 1.88 valves 360 head.
I can only go by what I remember reading I'm not claiming to have the stone tablets, if I ever move away from the 340 platform which I will add I will take over either one of those motors up to 500 plus horsepower it would be to move to the B/383or 400 but this was a budget build thread... No doubt about it 383 Rocka 202X won't outflow a 906
