Default Is this enough for my 408?

I am interested in buying the following:

Delphi 42lb injectors & 255 Walbro in tank - will these be enough for my 408? what about with a 200 shot of nitrous on top of it?

Thanks in advanced!

They may be a little thin with the 200 shot not totally sure. But my experience was, I bought 42's for my procharged 347. I quickly outgrew them when I installed the 408, I am FI and that does make a difference. But my advice is, if you are having to buy new injectors anyway, unless you are getting a smoking deal on the 42's, personally I would go straight to the 60's.....JMO

42's should be good for the 408. Are you planning on running the 200 shot dry or wet? If its a dry shot 42 are alittle on the low side.

A single racetronix pump should be right on the edge, might want a boost a pump for the nitrous hit.

If it is a wet kit the injectors are plenty. As for the pump it is fine for the motor but you will need alot more fuel for the 200 shot. You have a couple different options to handle that much power like our Stage3 street kit or a stand alone nitrous fuel system.
