...crossing off the list of small stuff. Bolted on the Jegs "Magnum" thermostat housing (#53251), sensors installed in the intake, and got a 45* heater hose fitting to make connecting to the heater hose a cinch. Have a nice HVH "Super Sucker" 2bbl carb adapter ready to bolt on, and used a children's Tylenol syringe to pre-fill the ram and ram hoses - worked awesome, very little mess, exhaust is nearly done, fuel lines done. Getting close to plugging in the EFI wiring...and firing it up.
