I have used several of these pertronix conversion and demon carbs and have never been disappointed 👍. I love getting my old stuff working better. I'm an old farmer who likes to keep my old stuff working.

I put this carb on a 364 Nailhead in a 1960 buick. The carb runs very well out of the box and it is easy to tune. It is very convenient that it has bolt patterns for square bore and spread bore. There are a lot of options for vacuum ports and throttle linkage, so I had no trouble getting the throttle hooked up and the Dynaflow transmission kickdown working. The only cons to this carb is that the tuning kit with metering rods and jets is quite pricy, about $80 for the kit. I have also had problems with the locking nut for the secondary air door adjustment. The casting is very thin where the nut threads in and it has 2-3 threads, so it is very easy to strip the fitting and then you will need to epoxy the nut in place, losing any ability to adjust the air door in the future.

I have a chevy 427 and it is beefed up cams and pistons and need use 91 or better fuel type. Would this be a good carb for that set up meaning would a 750cfm be enough or do I need to get the 850cfm? Also what would be a really good intake manifold to go with it? It is going on a 1968 Chevelle 427 SS! I have a Holly 750cfm and it is dieseling when I turn the car off. I was never a fan of Holley carbs and I really want to try the Demons. What do you prefer. I want the monster power and responce!
