i have run a lot of different things, seeing that half my income is buying cars fixing them up and selling them.... the accell parts are so so, its been hit and miss with them sometimes they work great and dont break, sometimes they never work, and sometimes they work for a little while a break... they're got a decent warranty though and generally break in the warranty time..... the pertronix units work very nicely.... i've used them quite a few times as well.... keeps your distributor looking stock but and they function well.... either kit works great... the pertronix is a little more expensive, but a lot easier to install and has a lifetime warranty instead of a 1 year
