power goodies

[78Suburban]

Here's the deal, I have an edelbrock performer manifold and 600 cfm carb /w manual choke on my old '66 project that I have pretty much abandoned. I have considered swapping it onto my burban's 350, but I hate to loose the automatic choke that is so convienent on the burban. How much cfm did stock carbs on the '78 350s push? I really hate to tamper with the burban because its so reliable, and if it ain't broke don't fix it. So how much power would I gain by swapping in the edelbrock goodies, and is it worth it.

I have also considered swapping in my old flowtech headers, but I really hate the idea of transmission linkage clearance issues that I could run into, after fitting them in the old '66, I swore that I would never fool with headers again. So again, how much power, and is it worth the trouble?

Edelbrock carbs can be converted to electric choke....

The M4 series Q-bog on a '78 350 is rated at 750cfm....

Acquire a $105 B&M Z-gate cable operated shifter....

Roughly 50HP and yes it's worth it, if you're planning a future cam/cylinder head or both swap, then ya may wanna upgrade the carb/manifold or both depending on selected components.

so you're saying the stocker pushes 150 more than the edelbrock, wouldn't that one be better?

Run the Performer intake and the Q-Jet. You can buy an adaptor to go from square bore to spread bore.

I can't say better but is is bigger....

you dont have to buy an adapter b/c the performer has both sets of holes(square bore and spread bore).i would run the performer and trade the 600 in on a 750 holley,and put on the headers should be good for about 35-40 horses.
