Ok cleaning out garage and found some new old parts .
Have enough parts to put together a 496 tall deck bbc with 6.8 rods (short block)
also found a comp 290hr kit (must off been a good deal don't remember buying it )and
a comp solid roller custom grind 739/715 lift 252/260 duration on 113 lobe separation
Will either of these work in a jet boat application . Have a couple of choices on heads laying around
ProAction 320's and dart 305's . Trying to reuse some of this instead of buying more if I can
