Hey Bog\'n

I was on a tight budget and couldn't afford the 450 cfm carb. If I had it to do over again, I would use that instead of the 600. I am able to tweek it to work good though. I did some tricks to it make it very adjustable and work good off road. I through the carb on to see if the 4bbl idea would work and to test the performance and reliability of the system. My actual goal is for Fuel Injection, but I would rather spend $200 and have it not turn out over $1200. Stick with your 450 cfm, It is just right. I never put it on a dyno, but imagine I get the same as you. I can't afford to test it yet. I am very happy with the outcome and am glad I didn't drop in a small block V-8. As far as my ignition, I have the EEC-III system and it has a 4000 RPM rev limit built in. This distributor doesn't use vacuum advance and is a mystery on how it actually works. I set the timing to 16 Degrees BTDC and it works good there. I bought a Performance Distributors ignition module and that gave me a better ignition curve and got rid of the rev limit. I use my Holley ignition to limit the RPM's to 5000. This setup seems to work good. This setup didn't give me much more power, but it did improve throttle response and prevents it from loading up on the slow parts of the trial. The reliability is good as well. I need to replace my steering gear box. It is leaking like there is no tomorrow and I am inclined to believe it. The shaft housing is oblonged from the years of use and seals won't help. Do you know of a good source for one? Let me know if you do. 6=8 buddy, I'll talk to you later. Eric

Re: Hey Bog\'n

I plan on sticking with the 300-6 for years to come, but the Holley 450CFM is a little on the small side for my engine. I am looking at getting the Holley 4di 700Cfm fuel injection set up. BTW: My cousin has a F150 With a 351W with 4bbl headers and cam, and I can smoke that Windsor off the Line. I'm up to 80 MPH before he can catch me. as for the tailshaft houseing, I'll go look over at the nieghbors house, he runs a little tranny shop....

Do'n it with only 6 cylinders!

Re: Hey Bog\'n

That is the exact same injection system I have been looking at.
