    • Performance
Ordered this carb, arrived the next day, bolted it on after installing linkage and air cleaner threaded rod. Fired right up after fuel entered it and I only had to raise the idle slightly as my 72 Pantera has a 351c with a manual gearbox. My old carb had a hesitation and this one’s works awesome.

    • Hit and Miss
put one on my T-Bucket works great out of the box. neighbor put 2 on his comet - both performed poorly, switched to an Edelbrock worked great. I think it's just hit and miss with these.

    • It works and carbs are forgiving
I've had to adjust the idle screws, choke, was running to rich out of the box. I love carbs, and messing with them is what I like to do, but I don't thinkni would buy another one
