4bbl intake for 318
Edelbrock
* LD4B ... Going price...... $175 and 'North', if you're lucky to find one.
No question that the LD4B is the 'optimal choice' here for performance, but >
--------------------------------------------------------------------------------------------
* Streetmaster 318 .... Can be had for $75, and some for 'South' of that price.
On a 'stocky' 1973 318, the Streetmaster will work fine.
Small plenum, short length runners, with narrow ports. Can
deliver an adequate throttle-response on the low-end.
The small runners were designed to improve port-velocity
at lower speed, which in turn was to promote better gas mileage.
From {Idle to 4500 RPM's}, this is a functional Intake for in-town
general driving and highway cruising.

Nobody is going fast here anyway.
