I have the Mallory HEI, worked all right for a while, but now I seem to be having issues with the advance not returning all of the time, MSD next time I reckon.

I love it, more power, smoothed out the idle, crisper throdel, can't complane for 200.00 with wires.

Here's a link to my 401/HEI/TBI, it's been a while since I started the project but I finally got it running and broke the engine in.

Bothered by the fact that everyone thinks they need an Hei. Run a 78 and later factory distributor or a pertronix ignitor. You are just upgrading from points to electronic. It is just a switch. You aren't talking a big HP increase.

The other 401 I built and put in my 79' Jeep has an Edelbrock carb, Performer intake, Mallory Unilite Distributor and an MSD Box. I built this engine for my 77' with the same internals and wanted to try something different for myself so I went with the Airgap/HEI/TBI combo. My next 401 build will have a torker manifold and some other ignition setup. I like to mix things up, no sense in having three of the same. Edited by motiv8ya - Mar/09/2014 at 10:53am |
