Edelbrock Timing gear and chain set

Myself I never had any luck with Idlebroke, No way would I think of ever touching that chain...

I bought my 67 it came with a Idelbroke Carter/weber Carburator & their air filter.. The filter doesn't fit their Carb very well,, hows that for piss poor engineering... Ironically it fit the Qjet better...

 

Well I'll stick to my gut and order a TA set, this guy has 2 sets brand new in the box for some reason?? Maybe he bought them before he knew about TA and realized there's better out there now it time to cut his losses
