Just got to add meat to the block for the rest off the hemi head to sit on and then fabricate an intake to fit.I'm confused.....Since a "real" Hemi engine heads have studs on the underneath of the intake passages and has cast/machined bosses on the lifter side of the block to accept the head studs (which are situated directly under the intake port) and secured with nuts, I'm not sure how you can retrofit hemi heads to a B/RB block unless it's a hemi block plus all of the other valve train components....please explain....

Is the "meat" you refer to, the cast and machined stud bosses on the lifter side of the block? If so, what type of material are you using and how do you attach it to the existing block? Do the rocker dhaft oil supply passsges on the hemi head line up with the existing oil supply passages? Do the coolant passages line up as well? Will the block require sress relieving after welding on the stud bosses? How do begin to fabricate the intake manifold as the hemi configuration is totally different in shape, area and port approach angle? Would you custom cast a manifold or make it out of pipe and a welded plenium? There are very few people that have the skill, ability and resources to accomplish this formidable task.....perhaps its just wishful thinking...just my opinion of course.Just got to add meat to the block for the rest off the hemi head to sit on and then fabricate an intake to fit.
Love this post! I believe you can bolt on Stage V Engineering Hemi conversion heads on a B383 but you still don't have a real Hemi. Do they even make an intake manifold for that conversion or do you have to make your own intake?This reminds me of bolt on BOOBs! Either it's a HEMI or it's NOT
Stage V used to make that intake manifold. I’m not sure they still produce it or the heads. The conversion heads were specific to the B/RB blocks and had external oil drain backs. Even the rocker gear was specific to the conversion heads as the exhaust rockers were much longer than a stock hemi as the pushrods couldn’t lay back as far due to the wedge block not having cast in pushrod reliefs. If I recall, even the wedge block had to be ground for pushrod clearance. I think I could probably do the block mods to get hemi heads on it but it sure wouldn’t be worth the time, effort and expense involved.Love this post!

Well,,,,,,you know how to push my buttonsyour only real shot is a STAGE V conversion
find their website
I have done several of their conversions
easy to workwith
some pushrod grinding etc
you will need a hemi cam core and all the valve train parts
manifold will be fun mighthave to cut a RB manifold up Hilborns will be easiest
getting compression is tough with small cu in hemis
Hemi heads work best with blowers or large cu in
talk to the stage V guys about it
There use to be a machine race shop in Des Moines, Ia. that use to do the conversion. It wasn't cheap but you had a hemi when they were done.Is the "meat" you refer to, the cast and machined stud bosses on the lifter side of the block?

Or you had a circle track car, were trying the meet cubic inch requirements and still have the advantages the hemi offered. I doubt very few of those engines went into street driven cars.Nope! You had a clone,tribute or recreation................
I got a new Isky cam for my ist gen, 354 Hemi from " Hot heads" They can tell you what all they have for early hemi's......MOI have a 56 Desoto 330 ci Hemi in my 52 Dodge B3B pickup. I got the Hemi for $250 and then got a quick education on Gen I Hemi's. First off, Pretty much anything before 57-58 does not interchange with anything else; what I mean is that the Desoto Hemi's do not interchange with the Dodge or Chrysler Hemis; same thing between those 2. In 57/58 Chrysler standardized the hemi line. Having said all that, there are some parts commonality between the first Gen hemis and small block Mopars, specifically like the distributor (I am running a SB Electronic ignition on mine). In other words, gen I hemis share more in common with small block Mopars than they do with the big blocks.
You really should check out HAMB.com, also look at what Hotheads.com sells. You are going to find that parts for these motors are not all that easy to come by. No one makes a cam for any of the first gen stuff except the 392; you have to have a core which gets welded up and recut. If you really want to enjoy the car and are not hemi fixated, you are much better off putting in a more modern engine. If you want to stay relatively "old school", then drop a newer 383 or 440 in it; if you don't care all that much about being old school, drop in a 5.7 hemi with modern trans and enjoy it; or go to a junk yard, find a 5.9 (360) and trans and transplant that; you get a roller motor, relatively simple EFI, lots of available parts, serpentine system, etc.
Well just shut the front door....live and in living color....a low deck hemi block....and only $1600....what a deal....wonder why its for sale? I think I'll pass....if I really want a real HEMI, I'll write the big check and buy one...complete, dyno run and ready to go....just my opinion of course.Or! Just buy this one....right here on FBBO!
