A Mechanic friend is helping me rebuild a 67 Fastback Mustang in the UK.
Approaching the final stages after 10 years. Need to make a decision about
the most appropriate Carburettor and Exhaust System. Engine is a 351
Cleveland. Looking at the 650 Edelbrock "Thunder" for the carb and either
"Flowmaster or "Magnaflow" exhaust systems.
Any advice, pros and cons or other input appreciated.
Rule of thumb for na engines
CFM = (CID * rpm)/3456
multiple this by your volumetric efficiency.
The 351C is a pretty good engine, call it 90%.
(2281500)/3456 (show all your work or lose 5 points)
660 * VE
660 * .9
So the 650 sounds like just a bit of overkill, but probably the best
bet without running out of breath. But make sure you get a good
manifold to go with it.
I'm partial to the Flowmaster. But that's me.
