'The 383' ~ Getting Those True Factory Horsepower Ratings

fratzog lover said

Would be neat to assemble the parts today and build one. Would an RPM intake be comparable in todays world? Or an old dp4b? The cam is the easy part.

Intake and Carburetor

I always used the Edelbrock DP-4B with the Holley #3310-1 {780 CFM}
'Back-in-the-Day'.

Just liked the Mid-Range Power of that Carb and Intake Package for the Street.

On the 'Edelbrock Performer RPM 383', it has a slightly wider intake port runner than the
DP-4B.
