I know a guy that builds nothing but dodge engines(a mopar freak)i will give him a call this weekend and see if he knows what can be done for bolt on power.
Just to let you know how much of a freak he is.he bought 2 old chicken houses(the long ones that chicken farmers use). he has 1 with old mopar muscle cars and the other he uses the front for a garage and the rest for part storage.
he has a 70 hemi cuda and a 68 hemi roadrunner the rr he bought brand new and completly restored it a few years back. not to mention the other toys. im gonna mention a couple engines he has that some of the older guys may have heard of. a 413 wedge, and a 396 i think hemi. they are rare to find the hemi was mid to late 50's and was in a desoto ,the wedge was late 50's to early 60's.he ahas a few of each. dad bought a 413 wedge cross ram from him (2 4 bblsitting diag from each other).dad is working on a 36 ply coup he is gonna squeeze it into that. this guy built a 340 for dad ,(the origional engine)for dads 69 dart swinger dad had to add severe heavey duty chain to the front.everytime he would kick it in it would snap motor mounts.
so as you can see if anyone would know what to do it would be him,he does keep up with the new stuff also.
