360 Intake and carb help

[Daves74chally]

I figured this would be the best place for advice. I am looking for what Intake and carb i should get for my 74 360 motor. Also since im still 18 living with my rents i dont have a ton of money to spend on the top of the line gear. Im just looking for good performance thats not so hard on the wallet.  If it helps you guys i just a week ago installed headers and 2.5 exhaust(shaved 1/2 a sec of my 1/8th mile time). Thanks alot guys!

What do You have now?

Stock 4 barrel intake and stock thermoquad 4 barrel carb.

[422STROKER]

Maybe a Edelbrock Air-Gap or RPM and a Holley carb like the 3310 750 will do you.  How does it run now?

I thought the 750 is too big. About the intake im not sure about like a square bore or a spread bore. What would be best.

[422STROKER]

That 750  is a Vacuum secondary model.

it should help on the dragstrip and have decent manners on the street for you.

You can go with a 'summit'/china brand airgap style intake manifold that is cheaper than the edelbrock. Quality suffers though. Performer RPM intake is a great one, however with the thermoquad you'd have to run a adapter over to the spreadbore intake.

Whats the rest of the entire car combo? Factory intake is just as good as the edelbrock performer intake, just heavier really. Intake will only do you so good if you don't have a cam change, or even converter to go with.

I think ill go with a new intake so that i dont have to mess with an adapter plate for the most part. I would just like to know what the best carb would be for my money. The motors really just the same from the factory except for the headers I installed. I just dont know what carb would work well with this motor.

Gear ratio dependent, the 750 could be to large for great street manors. A smaller 650 wouold fit the bill well if you have 3.55's or numerically lower gears. Even more so with 3.23's or 2.76's etc.......

With that said, if you want to change the intake and carb, spend for the RPM and figure out the carb as per my suggestion on gear ratio.

IF it were me, I'd look to a cam change. Then gear ratio. A street strip car with 4.10's perform well.

The only problem the T-Q should present is tuning the idle and cruise curcit's since rods are not at the corner store. Many seem to frown on bending a AFB rod 3/4 inch shorter to work with a T-Q. Why? I don't know. It works.
OH, also the AFB step up springs will work in the T-Q. There smaller, but will function fine.

I got an Eddy RPM manifold you can have cheap. The thermostat housing bolts have been re-tapped bigger. Otherwise good. I'll be getting a new carb. soon too. Mayby a package deal for ya'   It's a Carter AVS   650.   Was on a 375 h.p. 340. I'm getting the same thing but a thunder series with electric choke and endurashine finish. I'd say 100 bucks takes both for you.

[Chryco Psycho]

I would use the RPM & the Holley HP 750 Street series carb

[Daves74chally]

really? you guys seem ideal on a 750. I always thought a 750 was too big.

   About what he said, about what he said.  $100 is a decent deal for an intake and carb if you aren't picky with what you want.
