How do you Convert HEI to Mopar
I am presuming he checked the timing as I, and apparently you would. But you're right, he may just have assumed.
I know in the swaps I've done, I only had to alter timing once, but I hadn't checked it before the change.
One vehicle was pig rich like the one in the vid, and the HEI made a significant diff as in vid.
I've experienced the same improvement when installing an MSD, timing set the same before and after.
The hotter spark is definately improving fuel burn.
