Review: Easy installation and tuning good power - After a little tuning it runs great out of the box I replaced an edlebrock 1406 carb with this on my 79 400sbc and it runs like a new truck. for how easy it is to install, the only thing to note is it doesn't have an air cleaner stud and the mixture screws on the base plate are a little hard to get to but that is mostly me not having a short enough flat head screwdriver, for the price and ease of installation it worth the cost

### ⭐⭐⭐⭐ Works well

Works well

### ⭐ Casting flaw that causes a huge vacuum leak. Will not run right.
*by A***R on October 29, 2024*

Casting flaw in base plate. Did not see until we spent months trying everything to get it to run right. Took carb off and noticed a casting flaw. This flaw has the media blast marks so this was done prior to finish/milling of the unit. Secondary air flap spring was broken needed to disassemble and reinstall spring. Quality control is lacking. Sent numerous messages through Amazon to get resolved and no response. Just want a new one or refund.
