Got my me carb!

[Mrturner1]

Got a brand new Holley 650 dp to replace the Edelbrock 650 AVS I cracked tightening it down. I'm pretty excited, never had a Holley before

Nice!

In my opinion it's a way better performance carb over a edlebrock.

I have heard this from a few different people and I hope you're right, I'm very excited to find out

Depending on how big your cam is, you may have to drill a couple of small holes in the throttle blades. When you set your idle, check to make sure that the transfer slot in the side of the primary throat is visible. If it isn't you are going to have some tuning issues until you drill the holes. You might not have to do this, some of the newer Holley's come from the factory with a longer transfer slot already.

Nice carb, you are going to like it. It looks like you have 4 corner idle adjustment so it should be easy to set for any cam.

What a bummer, I bought the door feedline from our PC and you can see in the picture how far off it is. It's the right part so I'm not sure what is wrong but it looks like I'm not starting it up tonight. What a bummer

Thanks for the tips I really appreciate it. This is only my third carburetor and the other two were Edelbrock 600 and 650 AVS, much different from this I can tell.

Cut it in the middle and add a section of fuel line to make it fit. It is easier to get the lines into the carb when you have some flexibility anyway. Some don't like the looks but the air cleaner covers it from sight.

Never ever do this!!
Especially on a carb that has an adjustable secondary and a 4 corner idle.
Fix the problem thru fine tuning the timing curve.

Thanks for sticking around my threads I always like having your input and mechanical wisdom. You've seen this thing from day one lol what a mess. It's lookin like it's gonna pay off though

depends on what your comparing. The holly is versitile. no reason you cant fine tune it to maximize its advantages. Its agood choice. lots of literature on it.

My personal experience has been that the edlebrock always seems to run smooth but doesn't quite make the power the Holley. At wide-open throttle the Holley performs better. Just my opinion

Edlebrock= Smooth, Better MPG
Holley= HP

I also got an MSD distributor so I can properly limit the initial timing for my cam, I was having a lot of issues because it's a big cam and now I don't have to drive with a locked out distributor

You bought a dual feed line for a 4160 series carb with no metering block in the back so the distance between the 2 inlets is shorter.

You need a dual feed fuel line that fits a 4150 series carb with the rear metering block.

Everybody thinks that Holley carbs are so complicated. It's because they try to do too much at once. If it is a new carb that you bought and it came with a DVD in the box. Watch it from beginning to end. There is a ton of good info on it about tuning that carb.

It will be like night and day from that Edelpuke.
