I am hoping to get by without premium. Probably will run 89 octane. Compression ration should be between 8.5 and 9 to 1 with 90 CC heads. Plan to use an MSD adjustable timing control so I can pull some out if needed. Really want to do a 440 so I can use the step piston design. Want to try to get some decent fuel mileage if at all possible. If there were more piston choices for the 413 it would be a no brainer.

I have one on my 440 right now, and I'm not very impressed. Like everyone has said the runners are tiny! It is probably done by 5000 RPM. Fuel injected 1968 Charger, 1976 or 78? truck/smog 440, A-833 and a Dana 60 with 3.54 gears. Averaged 11 or more MPG last year, would improve to 14 or so on the highway. I could get better mileage, if not consistently, out of another 440 with the Street Dominator. I would think my application would be good for this manifold but that's not how it's working out. Any 440, even a low compression one with a broomstick for a cam would demand and benefit from more air than this manifold can provide. I can only imagine better sorted out 440 in a motorhome would be strangled by the SP2P440. It might work okay on a 413 but not a 440. I mean a factory 4 barrel intake blows this thing out of the water torque wise.
I would use almost anything else, if this 440 makes it back onto the road, I'm definitely putting a Performer RPM on it

So if you had piston options YOU WOULD consider or go with a 413 motor and those industrial heads ?
Absolutely. It is the best motor Chrysler built for an RV or truck application.. Sodium exh valves are a big plus. I don't know much about the head chambers or what it would take to get any type of quench though.

Yes the ports are TINY.... specifically cast that way by Eddy ! DONE at 5000 rpm ? I’m surprised it ran up that high ! You need to explain your combo better

I don't know much about the head chambers or what it would take to get any type of quench though. Just a quick question at this point .... how much investigation have you done on the 413 ... past the knowledge of the lack of piston choices ? Do you have access to a 413 core motor ?

I've used and built 5 or 6 of the 413 industrial and or marine blocks for race cars and street cars  I use only the blocks, crankshafts and some of the fasteners depending on which heads I'm going to use The last one is going into my 1963 Plymouth Fury with a Mopar brand 4.100 stroke crankshaft in it, 7.100 long BB Chevy type Molnard brand rods. I had either Autotec or Diamond make the pistons for it for pump gas using 440 source 80.0 CC heads. I had the 413 crankshaft offset ground to BB Chevy rod journal size and increase the stroke to 3.91 and used that crank in a later model (1976 casting) 440 block for another pump gas motor with 440 Source heads

 good points seaBee ... so what have you done with all those heads  and exh mans?  Back in the 70's, two 413 heads, two exhaust iron logs and the iron intake went to make 1 new Toyota. No one wanted them.

No one wanted them. .....add that massive water pump housing AND the pump itself and yurr probably right ! Buttt ..... log manifolds ? .... these are actually an impressive set of exh mans ! The only issue they have that I'm aware of is ... IF the exhaust system is not properly hung off the manifolds - they can break when heated red and sometimes WHITE HOT.

No particular knowledge or expertise claimed Doc. I have read they make more torque down low than even a 440 and know the 413 industrial/motorhome versions were built to last. But I am all ears and willing to listen and learn.

Do you have access to a good core motor ? 440s yes, no 413 though. But I see the motor home engines for sale locally on craigslist all the time.

Mopar has made two different version of their truck and motor home motors on the 318, 360, 361 C.I. HD B motors, 413 and 440. they can come in the regular ratings and the -3 extra heavy duty rated motors, the 440-3 blocks and heads have extra cooling holes in them for the exhaust valves, the regular 440 standard rated home motors don't All the Mopar H.D. dash 3 motors last a lot longer under heavy use

I have NINE of these up in northern Michigan and if you would pick up four of these and hold two for me in Atlanta... it’s a deal.

As I said before ... seaBee had some good suggestions. I did some figuring some years back and DID FIND my first piston option and that was a set of std bore 426 max wedge 11 to ones SHOULD be pretty close to perfect with those industrial heads at almost ZERO DECK ....and fantastic quench BECAUSE it’s a closed chamber head ..... BUTTT that closed chamber is something like 110 cc !

How far north in MI are we talking? How soon do they need to be moved? I might be going back to visit family this summer in the Detroit area but no specific plans yet.

49633 ... near traverse city.
I have AT LEAST until October 5 ... it would be a pleasure to give these to someone who would actually DO something on the upgrade of this motor You living in FL now Doc? What part?
