03-29-2010, 07:51 PM
my dad bought a 99 silverado from a friend of was bagged in its former life and originally a 4.3 truck...well he bought the truck to build a drag truck out of...he also bought a 496 BBC off a rail car to stick in it with a powerglide....i was thinkin that maybe a 8.1 motor mount would work with the older motor but the 8.1 MM is a 4 bolt and the BB is a 3 does anybody make a 3 bolt to stock frame LS motor mount or are we gonna have to build some...though i would atleast ask b4 we start sittin the motor in

Check out the conversions & hybrid forum, there have been people that swapped them into older trucks, I believe they had to swap/ fab mounts.
