So i have a 1978 casting 360
I thought it was a magnum because of the vertical
intake bolts - i guess it was in between LA and Magnum
But Im thinking it is externally balanced - which means you
need ext bal flexplate , too . If goin automatic
Im just running it on a test stand to see if she is junk or not .
Im bummed its not a real magnum . But oh well .
Next issue - will available flywheels fit my BH .

Was gonna use it to test carbs , distributors , etc . And make
noise in shop in winter .

If I can get a six pack intake that bolts up - would be great
Didn t realize heads needed re drilled

Oh well jbc if thats the flywheel I need thats weighted -
Itd be worth it - otherwise its just junk cast iron .
Thanks, Andy

A cheap modman intake on needed list too . Lol
