If you use the Q-Jet, carefully check the fuel filter housing and carb inlet threads. Not only were these prone to cross-threading, but a dielectric difference in the metals of the housing and carb could cause unseen wear and potential failure. There is still an entire industry around fixes for this
In 1978 a failure in this area on the way home from work nearly cost me my mostly restored, freshly painted ($2800 for a paint job in 1978 was a boatload of money, especially for a 19 year old) 1967 GTO.
The housing blew out from thread corrosion and commenced to dump probably a gallon or more of gas on the engine before she lit off.
If it wasn't for a mysterious man with a fire extinguisher, who I never even got to thank, I would have lost the whole thing. Fire shot up 20 feet in the air when the hood was opened.
I was lucky and only lost the hood and everything not hard-metal forward of the firewall.
It took me 4 months of several hours a night work to build, by hand, a new firewall-forward wiring harness.
Carb, A/C, Hoses, Alternator, Valve Covers, and every other bit short of the core engine had to be replaced.
The insurance company totaled it of course.
I kept it and rebuilt it.
