Hi
Quick question I ought to know myself but suddenly not sure .
So 58 dodge 361 or 383 58 (?)—- I think it was first use of afb vs wcfb on mopar ? 300 E had 2 afb too
So rebuilt it twice — once outside , once myself could find nothing really “ wrong” , terrible , repeatable bog when secondary opened . Cannot be fuel flow as no problem to 90 mph and we know bowls are full when sec first opens . Replaced pump anyway .
Gave up and changed to 650
edelbrock , ran perfect out of box , although yet to have high speed bog test , but seems fine .
( Larger diameter neck , FYI and a lower carb body — I found 1” neck extension and opened air cleaner bottom) Without 1” it hits choke linkages .
So in doing this , afterwards I noticed the secondary air valve in the Edelbrock. ( described for the AFB in carter book too ) , but the carb I took off had no air valve at all , at first i thought missing (?) — aha- no wonder a bog — but close inspection reveals no place to even mount it , no shaft holes etc . Carb i took off had the normal progressive linkage to secondary too.
So ? were early afb made without air valves ? . = gonna bog? Are all afb narrow neck ? or were some larger neck a little later ? I thought afb and Edelbrock the same thing , but obviously not , or there was a change in AFB design ~ 1962 , later ??
Or I am just lucky and some kind of marine carb landed on my 383?
comments welcome …
