"If you like 383s you can put 440 heads on them. The magnum or even the commando motors used heads from the 440 along with a 4bl intake. There used to be a kit on the market to turn a 318, 340, 360, 383 and 440 into a Hemi. The kit said it gave 1.5HP per cubic inch. The price was crazy high and I was close to ordering one for my 440 to put in my 70 Challenger R/T." God, when will it ever end? It's been 40 years I've been hearing this BS and it seems to be handed down from generation to generation.....all 383's have the EXACT same heads as a 440, at least in all the 'important' years. You grandmother's 69 Coronot wagon with a 383 2 barrel had the EXACT same heads as your 69 Charger R/T. The kit you refer to is a Stage V setup, and it never was a small block kit, only big block.
Yes, you can make a hemi out of your b and RB wedge engines with the Hemi Conversion kit from Stage V engineering. Some work is required to the block so the valve train and oiling work. I put one of these in my 1959 Chrysler 300 E and with a very mild cam it made over 530 hp at 3400 rpm and 542 lb/ft of torque at 3600 rpm.
Hey George - you correct -since I was going to put it in a 1965 D300 1TON truck -it should be worth a rebuilt -right ?
Think you could build a fine standard 440 & have plenty of cash still in the wallet vs either conversion, but I guess it'd be cheaper than a Hemi crate engine.
Since it's been mentioned a couple times, the 70s 413 RV engines have a unique head design where the water pump bolts directly to the heads. I've also found these heads on some RV 440s too. They are junk for anyone who wants to build any kind of power. As with anything Mopar did, there are exceptions, I've seen stock 413s with the better 452 castings and even picked a 440 out of a 1970 motor home chassis with 906 heads (same ports as the 915 heads, just open chamber) and a 6pac bottom end. Mopar used whatever they had leftover until the supply was gone. Posted using the Full Custom H.A.M.B. App!
Also for you guys new to bb mopars, if you find a set of 915 heads (67 only closed chamber) they came with both small or large valves. Measure before dropping big money on them, and if you want to run them on a late 60s 383 you have to measure deck height 1st. Some HP 383s actually have a positive deck height. Ha and don't get me started on 516s or removable pedestal mount rocker shafts on non-max wedge heads....you can build a killer engine from factory parts, ok I'm done......end of rant.

Actually, there were quite a few (as you know). Bad ass engines in factory trim in their day... and the gm boys think they actually discovered the hp 383... As mentioned, just building a oem spec 375-440 is easy and will scare the crap outta most folks today. .
I don't know how long or what years, but Mack used Chrysler 413s in some of their lighter trucks. I think that says a lot about the quality and longevity of a 413!
You might find one in a D300-D500 big trucks but most of them ended up in the Rvs and other industrial applications. The only light duty trucks dodge put them in was the '62-'63 Palomino package D100-D200's (very rare). After that the only big blocks were semi-common 383s and very rare 426 max wedge In the Hpp and CSS/HPP trucks(only a few hundred maybe) Posted using the Full Custom H.A.M.B. App!
Keep in mind that many truck 413's have a 8 bolt crank that is physically longer than the standard b/rb crank. Much confusion over the topic. Posted using the Full Custom H.A.M.B. App!
I Have a complete a complete 65 413 all standard. Buffalo ny. If that guy had cracked blocks. He either didn't drain the water. Or worse yet, he is a demo derby guy.
thanks guys....i'm able to pick up the motor home motors on the cheap -so I have some put back....also seems to be those nice 67 heads stashed in a closet around the place....
