Default Intake

I am contemplating replacing the intake manifold on my stock 350. Is there much to gain, horsepower / efficiency, etc.? The stock manifold is painted (poorly I might add) and putting a new one on sounds a lot easier than cleaning the old. Looking at the edelbrock and summit intakes at $150 or less.

I wouldn't bother. I put an Edelbrock Performer on my "warmed over" 350 and can't tell any difference. Not worth the trouble. Any gain in HP or torque is quite small, I'm sure.

Edelbrock has done a nice job with their Chevy Performer intake, and you should see a bit of a performance boost. If nothing else, going to an aluminum intake will take quite a bit of weight off of the front of the car for not much $$$.

Default spend the $$ elsewhere

You have a 75 with like 250 stock hp. The intake swap alone might get you 5hp. Don't fix what isn't broken. Clean the stock intake up and keep driving the car.

if you can get a performer or performer rpm for a good price than i say what not? by the time you do all the work and take the old on off, acid wash it, scrub it and paint it or whatever you decide to do.... for 100 bucks bolting on a nice shiney new one sounds alot easier and there will be some improvement. go all out and get some nice bling rocker covers while your at it .

I installed a 2101 Performer in place of the factory intake on a '78 L82...it made a noticeable difference.
