289 High Performance Distributor

Why did the 289 HP not have vacuum advance?

Did any other factory v8s not have vac advance during this era?

Re: Ford DS II ignition upgrades?

I’m going to try just a coil upgrade first and see how that does, and go from there. I do have a question about coils though. How do you determine what coils are compatible with your ignition system? Do you need to match the ohms of the stock coil semi-closely to an aftermarket coil. If you use one...

Re: Ford DS II ignition upgrades?

Just converted a 1974 duraspark to a HEI using a pertronix module( the one with multiple sparks and rev limiter built in) and tfi coil. My understanding is that if you keep plug gaps at .040 or less you can use the small cap. The engine is a 10.4 to 347 that pulls fine to just over 6000 rpm so far.....

Re: CAM GUY'S , just when you though theres nothing new

If this technology could be used on a 350 chevy or 302 ford, how would it improve the average street strip hotrod? To do it right, it would need to be used on a double overhead cam engine. Something like the Ford Mod 4V engine. With the system, you would effectively have a short duration cam for va...

Re: Advantages of electric cooling fans vs mechanical

A Derale 16926 fits a 1966 mustang like it was made for it. It's a fan/shroud combo. The sucker draws 20+ continuous amps, and blows like a hurricane. Zero problems with cooling on the street, and I'm even using an old Moroso electric water pump drive that spins the stock water pump! I did use the '...

CJ, Thanks so much for your sensible post on a fantastic topic. You made some points much better than I have been able to.
