The tall deck uses a massive 4 ring piston. This has to be replaced for any kind of performance.
To replace these pistons with hi-perf stuff. You will need +.400 rods. Harmonic balancer is not hi-perf usable. Also not, are the two thermostat intake. Water pump and distrib.
There are very few, if any "street" type or tunnel ram used/affordable intakes for a tall deck. Most will need spacers. They leak. Then an adjustable ring distrib. or intake/distrib mods.

Tall deck truck heads won't work (flow) without massive work $$$$..Best to replace with better parts.

So you end up with 1-block and 1- crank.. And a motor that has limited ready made headers/accessories for street use.

Sell the block to a Drag/boat/puller guy. Get a short deck block and build a usable/affordable BBC engine.
