I am currently using a standard GM HEI unit on a tripower setup and cannot get enough rotation with the distributor to properly set timing . I have tried numerous times to "walk" the distributor and be able to get the timing set, but the HEI cover is so large I have very little room for adjustment. I am wondering if there is a smaller unit that won't hit the back carb and will work well. (I'd really like to use an HEI unit if possible.) Thanks in advance

There are lots of small cap options. But, I think they all require a remote coil. Some like a factory points type dist with one of the Pertronix Ignitor elec conversions installed. The Ignitor III has a built in rev limiter.

The MSD Ready-to-Run is popular.

There are some dist that require a box. I had to buy a replacement box. So, I don't recommend the box, for street cars. Just one more part to go bad. IMO

HEI and tripower do not go together as you learned. This has been covered in a number of posts and you might find a recommendation within one of the many posts. Use the SEARCH option in the upper right.

I like Pertronix and got one of their electronic distributors and matching coil because I wanted a factory look and not the big HEI cap. If you rather not spend the money on a billet distrib., I would simply get a factory distributor and go with the Pertronix electronic conversion - also have done that and have been satisfied with the results.

Thanks guys! I installed a rebuilt distributor and converted to the Pertonix setup with external Pertronix coil, installed new wires, set the timing (easy), and the car screams :).

Perfect. Just make sure you have 12volts going to the Pertronix as the instructions say. Factory wiring/points uses a resistor wire and drops voltage down to around 8-9volts. :thumbsup:
