Off hand the first thing I can think of is the piston, while being forged, will give you too high a compression ratio. Call "Skip White" and see about a piston change.
Next would be if your present cooling system will work with the h.p. demands.
More questions. Will your oil pan work with the new Dart block? Is an oil pump included?
Timing chain, front cover, all tin, water pump etc.
Ask what can be transfered from your existing engine to the new engine and what needs to be purchased to have a complete and running engine.
Ask for and get a detailed parts break down with make, model, type, etc. along with individual prices, including all machine work performed.
Lots of time "Skip White" turns out to be a small warehouse that subcontracts all machining, balancing, out to a no name machine shop that you will not be able to contact if some thing goes sideways.
"Skip White" also might use the "on demand" ordering system where Skip gets your money and then orders your parts and has them sent to you direct from a different warehouse. Even less warehousing costs to "Skip".
Always use your your bank credit card with a 30 day cancelation ability. Talk to your bank. Never know when "Skip" might skip with the money.
After the parts have arrived at the place of assembly, inspect and verify every thing is as it is supposed to be. By the by, do you have a way to get the block off the truck? It will probably come on a pallet. Unless the driver has a fork lift behind the truck, it will be up to you to arrange the removal and situating of said pallet. Do not forget to tip the truck driver if he has to help unload. Also have have cool drinks available.
Do not hesitate to call "Skip" or if you have parts discrepancies to stop payment thru the credit card company.
One last thing. The block will probably weigh more so you might think about another leaf in the front spring.

One last thing for now - do not use Fram products in any way, shape, or form. Not even during break-in.
