I am thinking of dropping it in a 68 Charger. Just building a good driver, not worried about 1/4 mile e.t's. Its really cheap...and I can dress it up with stuff I already have. What do you think?

I have never opened a motorhome 440 but I stroked a 5.9 from a 97 Ram pickup. I got a chance to buy a 98 5.9 from a Jeep Cherokee from a guy from a local dealership to put up for a spare block and stuf. He told me it was a R/T motor but didnt have the R/T heads. I pulled it apart and there are lots more cast-in bracing in the vally area that my other one doesnt have. Would the m/h 440 have all that extra meat in it to make it survive due to the extra stress on it everytime the thing is cranked? I'm sure there are heavier duty things in the trans to keep it alive pulling that more weight. Would make sense to me anyway. Am I wrong? I would use it and maybe do a cam change for more hp due to the one in it should be cut for tons of torque. 76' Volare, 5.9 magnum w/Iron heads. New best 10.68 at 123 mph 1/4 mile.

Depending on the motorhome, it might have a parking brake on the tailhousing. Aside from that, every one I've ever seen was a short tailshaft. Search this site, there are quite a few threads on motorhome stuff. This question comes up every few months... Parts I seek: driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set 16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better. 69-73 C-body caliper brackets and/or splashields Send a PM.

The plain shorty(not THAT short) ...was from 73 and up. In any case .. the RV trans is a good piece - Premium parts used in there.

Is it a big block trans , if not it won't fit BUT you could mix and match parts from the motorhome trans to make the motorhome trans a car trans , just be careful with the front planet choice .

Since the tranny was shot and needed rebuilt anyway, I just had the builder use a standard output shaft and tailhousing to fit going in my truck. My next door neighbor is scrapping a 79 MH with a 440. I could check, but I'm willing to bet it has a drum on the end of it as well. BTW, this 440/727 is for sale if anyone is interested.

The only possible difference to it vs a passenger car 440 from the same year is the possibility of those weird water jacket heads, I think the casting number ends with 213. Theyve got some sort of revised cooling passages. Not sure if they came on 440s your year, but I believe some had them. Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street
