Fix 1973 international pickup with a 345 but needs new air cleaner
I just got this for a 1973 international pickup with a 345 and it bolted on and right started up. Have yet to really get it out and test it, but so far all sign point to it work much better then the stock carb that I have been working for years and just seem badly designed.The one thing to note is the air cleaner no longer fits as this one have a bigger top (it is about 5" across). The local auto-parts store had an air cleaner that fix, but it is so big that it hits the water housing thing on the engine and now I am looking at getting a space (Edelbrock 8092 Air Cleaner Spacer) and hoping it is all not to tall and hits the hood.

First time ever that I got a plug and play carb that really worked that way. Hook it up and it worked the first time and didn't have to do anything but adjust the idle just a little bit. Been running good every since. This was a change over from a Rochester 2 barrow to this holley 2300 350cfm and it did require an adapter plate and was a real improvement for my 225 cu in dodge slant six. Added a manual choke kit but so far has started up without it even in cold weather, just a couple of pumps on the throttle and it cranks right over and starts, stays running until warmed up. I love this setup!

I have a '68 chevy 250 conversion in my Series Land Rover with an Offenhauser intake manifold and stock exhaust manifold. For years I was using a four barral Edelbrock cfm 500 but it was just oo much carb for the motor no matter how I tinkered with the settings. Rather than go down the EFI rabbit hole for big $$$ I opted for this Holley. The firsty one I ordered had an electric choke and it was a disaster. It worked great for one hour after I installed it, then when I went to drive it again it spewed smoke, had no vacuum and could barely get out of the driveway. Wasted the rest of the weekend trying to diagnosi it, but finally threw in the towel and retuerned it. This time I got the manual choke which is what I'd wanted in the first place. The manual choke unit worked great right out of the box and the performance is vastly better than the 500 cfm edelbrock. Dont get me wrong, the edelbrock is a great carb, but all the classic symptoms of too much carb disappeared with the Holley. Now it is much smoother with no stumbling or bog in the middle. Bonus is my gas mileage his improved dramatically and added about an extra 50 miles range to a tank of gas. It's still not great compared to modern cars, but I will take it and the drive is much more pleasurable.

Fantastic plug and play carb for the International 345 in my 78 Scout. Only two vacuum lines needed...no emissions testing where I live so I was able to remove all smog controls and greatly simplify the routing. My stock throttle and kickdown cable assembly bolted right up, no adjustments needed. Added Holley electronic choke kit and Holley gasket 108-52, both highly recommended for easy startups and to protect the carb from heat far better than the stock gasket.

Night and day difference between the stock Holley 2210 and this 7448! It feels like a completely different truck. Very well worth the money.
