MAS Ignition Distributor w/Cap and Rotor Compatible with 606-02302 606-02257 1103838 1103698 Chevy GMC C/K Pickup Truck Van Camaro 5.0L 5.7L 7.4L

It seems to be an exact copy of the factory original and works great. However, I would keep a spare factory GM module in case the no name module fails. Other than that it works great and is worth the price.

Update: I happened to get a faulty distributor and after several communications with the seller, I was sent a replacement which works flawlessly. It solved the issues I was having with my old pickup. Spend the money on a better quality distributor. I purchased this one to replace original with burnt out pickup coil and have regretted it ever since. It is installed and timed correctly and my truck runs worse now than ever before. It has so many random misfires it's not even drivable at this point. Don't buy this unless you like chasing your tail around in circles trying diagnose a problem that could have been prevented by getting a better quality distributor. And FYI, my truck ran perfectly before distributor was changed and that was the only thing changed at that point but have since changed coil, wires and plugs to eliminate the misfiring but it's still there. I've finally narrowed it down to a poor quality/faulty distributor which is brand new.

Works great have had this for over two years and never had an issue

Works as it should. Fixed my map sensor code also. Old distributor wasn't working well and was causing miss fire and hard starts. Now she runs and starts great

Installed and set timing, back on the road...Rotor came damaged and the new ignition module failed after a week bought new rotor and reused old acdelco module no problems now.
