Great responses gents, thanks,
ZedHead and Captain Obvious regarding GM HEI. Yes, I agree the placement of the HEI under the distributor cap was a bad location causing premature heat failures. Heating and cooling of electrical components over time isn’t good nor the constant vibration. I know people,have successfully put these in. There are so many manufacturers of these. Unfortunately, you never know what you’re getting anymore. So many companies rush off to China to save money and end up with inferior products. The problem is you can never tell what you are getting. Even the Delphi ones are probably made there in the same couple factories. Go on Amazon and look at the review for these GM HEI modules….they are not good.
ZedHead, I did some research and you’re correct. MSD was bought out and now has moved its production from El Paso to China. Many unhappy customers with the later Chinese models. Same reasons stated above. It’s hit or miss it appears. I can go on a long rant about what Chinese production has done to America. The bottom line overseas production has benefited companies balance sheet while killing US jobs and undermining our national security. I resist to say more.
So after some research I’m considering another option. Pertronix has a product called the Digital HP module. Saw only one short thread on here from 2017. Again, I’m not trying to get power increase. I’m looking for reliability. ZedHead commented on the 2017 thread but the price had just hit the market and there was little to no feedback from car owners. After 5 more years the reviews are good. This product is made in the US, had good reviews and wires up exactly like the MSD at almost 1/2 the MSD cost. Amazon sells it and had free returns. I might test it and report back my findings. 95% 5 star reviews on both Amazon, Jegs and Summit. Haven’t read a bad review yet online,
Right now I can’t confidently drive the car any distance from my house and while it’s running fine now if I drove 25 miles from home and I had another failure again i won’t be happy and it would be a major inconvenience . If the car is not reliable then it defeats the purpose of what I’ve done to this point.
I’m willing to be the 280z Guinea Pig. If it’s not good I’ll return it.
