Where's the double pumper crowd???
Edelbrock 600
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

600 eddy would be good for a stockish 318 I also like a early to mid 70s chivy q-jet with the mopar throttle lever tac welded on to the throttle shaft for stock mopar 4-v linkage that works great on a 318 also,IMO any smaller holley would do.. remember 318 are easy to "over cam" which means they are easy to "over carb" also I have ran a 750cfm on a stock teen..had good top end..but the idle was pig rich and slow speed drivabilty was sluggish till 3000 rpms or so 600 eddy out the box was almost right on the jetting but still a tad rich,IMO good luck and dont over carb it with a stock cam dont forget to get the throttle presssure rod adjusted correctly or you will be posting about new trannys for it

eddie 600 is a good choice as it gives some room to grow. I have a 1406 on my magnum headed 318 with a 208@.050, .506" lift roller cam, RPM air gap and headers. I had to change the step up springs to the pink or natural, jet the primary down to .095" jets and .073/.052 rods and the secondary down to .089 jets. that was tuning with an LM1.

Don't forget to use four barrell intake gaskets not the steel shim two barrell gaskets. AMHIK. One of the first things I learned on my first mopar.

if you plan on keeping it under 300hp then the 5/16 fuel lines will be fine.

Stock (quiet) mufflers are very restrictive.
Quiet doesn't mean restrictive, nor does loud mean best flowing.
Car Craft, and others, have done a number of tests and the Dynomay Hemi muffler is the winner. Quiet, free flowing, cheap. On the dyno, with a sound meter, real tests not someone's guess.
I agree with you but most stock mufflers I have seen are both quiet and restrictive compared to an aftermarket turbo style muffler(dynomax). The 5/16 fuel line is sufficient.
