Re: To HEI or not to HEI - 69 C20 with Stock 307

I think all these people that say there truck runs better, smoother or starts easier with HEI are fooling themselves. They get a truck that's not running right & rather than just do a tune up they decide to upgrade. They put an HEI in and "It runs so much better now." Well of course it does, you did a tuneup when you installed the HEI. It would run just as well if you had just done a tuneup. I'm willing to bet none of them took out a well setup points ignition to install an HEI for a good comparison.
The only real advantage to an HEI is less maintenance. However as others have mentioned they can fail & leave you stranded.
