After using a standard rebuild kit, getting this kit made all the difference. My truck runs 100% better with the changes that I was able to make while not wasting time with trial and error. I highly recommend this kit!
After installing carb kit my 455 is running better than it ever has, from idle to full throttle
Best results ever. Been dealing with issue for 15 plus years and now carb is perfect!! Unbelievable
This kit contained everything I need to take my 200 horsepower stock engine to a 400 plus horsepower daily driver. I find that the kit has made the carburetor extremely tunable and the online videos that support their products are fantastic. I simply emailed them my engine specifications and they selected the kit that I needed.
Excellent customer service. Custom kit made to modify my quadrajet to work on a newly built motor. Super fast shipping. How to videos are much appreciated. Took the guess work out of the trial and error process. Now I just have to build the carb.
HAVE NOT USED YET-SURE PRODUCT WILL BE OK-THANK YOU--KLH
This kit includes quite literally everything you need to rebuild and/or completely alter the performance of your Quadrajet. I admit I was skeptical having believed the disparaging names hurled at Quadrajets... no more. This kit, coupled with the excellent tutorial videos via Quadrajet Power's YouTube Channel, transformed my leaky, sluggish, tired old Quadrajet into a rock-solid and top-performing monster. I strongly, strongly recommend this company and this product - you will not be disappointed!
These folks are incredibly knowledgeable. The custom made kit took my car from dud to amazing. I will never buy quadrajet parts from anyone else!
Reference in instruction to air bleeds not clear as to their location on carb
