Holley Projection

Does anyone have any experience with Holley Projections. I have been tossing around the idea of putting one on my 1982 Chevy daily driver with a 454. I would like to hear if you have any opinions about them or likes and dislikes.

I have had good luck with mine and actually will be selling before very long. I am located near st louis. The 2d projection is only good to 275 hp but has a small block and big block switch on it. I am going to be around 400 horse so I have to sell. Let me know if you are interested.

My Q-jet runs better than any projection I have ever seen (open loop versions without an 02 sensor). I would avoid it.

Mine works fine i have the 4di system you have run a stock cam because you need 14lb. of vacuum. I would buy one again.

I would only recommend a newer digital (DI) system that uses the O2 closed loop. The early analog systems with the little knobs on front are just not worth it.

For the price of a new Holley I would recommend a junk yard GM TBI swap first. Even if you bought the tuning hardware it would probably be cheaper if your a DIY'r. If your motor is stock then just get a system off the same size motor and bolt it all on. Then just purchase an after market harness if you don't like wiring.

If you find lots of used ones for sale...there's a reason!!

Search under this subject and you'll find many people who don't like them at all, me being one of them. For the cost, just get a howell system.
