Motorhome engines are notorious for exhaust valves "tuliping". They build a lot of heat. A perfect recipe for future dropped valves! A teardown should be in order. you should start looking for a 727 trans without the e brake. My for what its worth.
84 D150 440/727 79 /6 swb D150 1964 A100 window van. Just because it has spark plug tubes doesn't mean it's a Hemi.
If ya haven't been there, ya just wouldn't understand.

the trans will have HD 4 planet gears but you will most likely need to swap the tail shaft to a short or long tail shaft.
with a parking drum brake on the tailshaft it has no "parking pawl" hooked to the VB to engage the cog wheel on tailshaft.
the TC will be the large 11-3/4" AKA 12" LOW STALL for sure if it was a MH chassis.
have a look to see what spark plugs it has. some 452 heads have the small 5/8" peanut plug (auto light 23) or use a 13/16" plug (champ RJ12YC)
have a look at the damper on crankshaft. some have a steel crank 6pac rods some have "bullet nose damper" cast crank external balance LY rods depending on yr/chassis.
trust me when I say shaving off a 30' MH chassis for a 440/727/8-3/4 swb 1/2 ton truck wakes it up.
I added a Holley street Dominator intake with a Holley 650 dbl pumper headers-3" pipes with 3" muffs and it is a beast with the 3.91 sg but 10 mpg.
3.23s not as strong off the line but 14 mpg
2.76 fair off the line but 55 to 125 mph is AWSOME! 12-13 mpg
should have the WHIPLASH cam broke in next week. that should really wake it up.
FYI..the Edelbrock 440 RPM intake is another intake that will wake the stock 440 up as well.
those 2 intakes on a stock lopo 440 are impressive for a bolt on with a good 650 cfm dbl pumper.

Will a valve body from a car/truck 727 solve the parking pin issue? Figured on a different convertor. Definitely A cast crank,that will be ok. Just have to find tail assembly. Will need to get motormount brackets,pan and pickup. Is the trans crossmember different from sb/904? I would be very surprised if that trans doesn't have the Park mechanism in it. Any Mopar powered Winnebago type MH I have peered into has always had a Park position on the shifter quadrant. Not that I have seen them all, just the ones I have seen. The last 727 I saw with a drum brake and no Park in it was a push button 64 D100. The best money you can spend will be on cylinder heads. That is where the power is. With the possible exception of Max Wedge heads, none of these heads will be made of iron. It's not that it can't be done with iron heads, just that the iron head will cost more money to get there than the aluminum. Just about any of the entry level aluminum heads are good for your HP goals with nothing more than having the valve job fixed and maybe touch up the bowls. That price will barely rebuild the ones you have never mind get them to flow 600 HP. And while I'm here spending your money have you considered a stroker? I have an under 9:1 493 that makes 500 hp on 87 regular gas. Kevin

What's the weight rating on your truck? I have a 3/4 ton and it has the short tail housing and two piece drive shaft. Mine is a 318 though. No idea if the BB would have the same options, but would assume so. Being you have an engine from a motor home, I would think the pan, pickup, exhaust, and mounts would all swap in. Not sure of interchange, but I dropped a 318 out of a van right into my pick-up with out changing anything. No idea on converter specs, but I would replace it anyway as the unit is out.
I have several tail shafts sitting here if you need one.

Have not even looked at any,I think I will look at a .550-.575 lift. When I get the pistons,I will measure them up then send the block out to get machined. Now checking on rods,I do not think I trust the stockers to hold up,why invest in working them over. Crank,I have one in mind,4.150 stroke,around $675. Will a center sump pan fit in the truck?
