Just went/going through the same thing. I was thinking of a msd-6425 ignition and a msd- 8970 retard. A magnafuel 500 pump running both regulators. And I'm still gonna have locked out timing and a crank trigger. I would love to go with the Msd 6520 and think this is the best dollar for dollar but I need to be able to retard atleast 11 degrees and the 6520 only is capable to retard 9.9 which would work great for your set up. And maybe run a seperate fuel pump for nitrous to avoid a possible lean out. That's my 2 cents.

Ok, so you have to lock out your timing on the msd- 8970 retard box too. If I am running a fuel safety switch to the solenoids (say set 6 psi) should I really have to worry about a lean condition?

Andy gave me a full lock out dizzy and with a safety switch I would think your good to go. Those clay smith are around 140gph right??

6 lbs is good for the safety switch. Start with retarding 2 degrees for every 50 hp shot of nitrous. That will give you a good base line for tuning. 👍👍👍👍
I don't like using the same fuel pump for both nitrous and motor but that's me. I use a Holley blue for the nitrous side and now a aeromotive with a bypass for the motor side.

I can see using a separate fuel system for racing but it just doesn't make sense to me for play. If you're running a safety switch then the nitrous won't fire unless you've got good fuel pressure. Maybe I will do some more homework and see what I find. I plan on running 78/78 fuel and nitrous jets with a 6-8 retard. I am thinking about running one of my gunnel tanks with a mixture of 91/110 and just switch to that tank when I want to run a nitrous pass. Edelbrock says to use 92 octane pump gasoline or better with 175 HP shot.

What about when the fuel pressure drops as the demand increases after the N2O fires?

I agree. i used the normal squared jetting 2 passes and dumped down the fuel side because it was so fat. It killed my plugs The recomended jetting from Edelbrock and NOS is a fat tune up for sure. Also spark plug gap plays a good role in the tune.  :thumbup: :thumbup: :thumbup:

going to take them out to valley head service in northridge to see what they have to say first.. they're wizards when it come to fixing iron heads. hopefully it wont turn into throw them in the recycle bin situation... gotta love a good craigslist burn from a fellow boater..
