Before you open your wallet, verify the title matches the VIN tag on the driver's side door post. The priority is good brakes and steering. Don't assume, have them checked and fixed. Old 2 ton brake parts can be made of unobtanium. Identify which transmission you have then go to "https://www.novak-adapt.com" and read about what bellhousing you will need to connect to a 454. The steering box location may require a steering upgrade. You will also need to convert from 6 volt to 12 volts. Water temperature and oil pressure gauges are mechanical but the fuel gauge will need adaption (see Tech Tips). Unless you are good at fabrication and welding, make a list of what you want to do and visit a rod shop.
If you are going custom (see picture), scrap the above and look for a donor chassis that can be slammed to taste.
"Adding CFM to a truck will only help at engine speeds you don't want to use." "I found there was nothing to gain beyond 400 CFM."
