what kind of alt is that? your plate looks like it gives more room plus you dont have a stock K frame either

Ray, you need atleast a 100 amp alternator for a street car w/ a lot of electric crap on it. My 100 amp is barely enough for my car, but my electric fan does draw a lot of juice.

I use the DMI low mount kit on mine by the way. Fits pretty good w/ the motorplate.

what alternator? the big denso is no problem on my challenger but on the A body it is a problem. notice in this pic i have the engine plate sitting on 1" pieces of wood to give it enough room. but they are not staying there, i just had to do that while i was dropping it in. i even cut some of the plate to give it more room.

Mine is the 100 amp Powermaster GM 1 wire that came in the kit that GregZ sold w/ the DMI bracket.
One more reason I don't like motorplates w/ holes in them. I had to trim the bottom of mine to clear the alternator, but w/ the way mine is mounted, I have plenty of room. I have the big Comp Engineering solid plate.

You have that cuda lookin good Ray!

the stock k frame is the biggest problem i'm running into but i will look at that but it seems there is less room by the frame

This might help...

Parts from Mancini Racing:

Billet DMI Alt. bracket # BMAB040-R (88.95$)
Billet DMI Alt. pulley # BMCT050-R (69.95$)

Parts from Summit Racing:

Powermaster 100Amp Alt. # PWM-8062 (239.95$)
Pulley to Alt. # PWM-181 (26.95$)

I had to modify one of the Alternator mounting brackets to line up the pulleys. I also had to make a small notch in the engine plate.

is that an A body? EDIT:oh, i do see the short balancer pulley pushes the whole alt back good stuff although its out of my price range by $300 but i may be able to make something work
