Torque Monster !

Well, yeah, more head flow more power but I just wouldn’t do it at a massive port size. AndyF is doing/did a 470 build for his Duster that you should check out. It is really cool.

For a motor home, IF I could fit a turbo need there, and I have zero idea what could be done, that would be a plausible route. A roof super charger would be better IMO if it could fit nicely. That’s torque on demand!
Boom baby! Boom!

The idea of a stroker with stock port heads equals a stock engine wasting cubic inches IMO. Hey m not saying there won’t be an improvement, but a wasteful one that doesn’t equal the increased size or effort.
All of that he ranked in this Theoretical exercise!
And that’s why I say, this is a very interesting topic.

I was meaning 270 to 340 cfm for 500 to 600 hp, so 270 would be about 500 hp and 340 would be about 600 hp, and in between cfm would be in between hp, with around 10.5:1 cr and a 285 ish cam. Wasn’t given the OP a blueprint to follow just what ruffly if you do this you get that.

I missed that this was a motor home :) did see a video where someone put I think turbo LS engine in one.


As for a motor home I guess I’d go with a 4.15 stroke and keep everything fairly stock. Possibly could add a very mild hydraulic roller. If we’re just throwing money at it.
