Default thoughts on these injectors and fuel pump

Like title says, I'm putting together a engine but not sure what size injectors
and pump to use, are either one of these any good?

Call Jon at Fuel Injector Connection and he will get you setup properly. You don't want to be guessing in this area. Plus he provides the data for tuning the motor to the injector which saves time and hassle.

Those are huge for 650hp NA

You can get away with 60lbs to give you a little room to grow.

FWIW the ZR1 at 650 boosted (consumes more fuel) uses 52lbers.

110lbers would make it a bitch to tune and be less streetable most likely.

Thanks for the replies, I do not know anything about size of injectors, I have started looking into injectors and I saw those, the advertising had the hook in but not quite set yet. So I'm thinking I will look for something like the factory supercharged LS engines
size injectors, are the factory ones good enough? Should I look for any particular
style or squirt pattern, the ones I have listed have 7 little holes in the end of extended
nozzle, whats the extended nozzle for? I'm sure there's plenty more I'm missing.

What about that fuel pump from Summit?

A 340 would be enough then. Same with 60lbers or 52lbers pull outs. This gives a little wiggle room if you decide spray a lil giggle on top.

The Ls7 102 should use the short injectors like the 52lb zr1 uses.

Thanks again for the info, I have thought about nitrous also but don't have a clue about
that either, but that is for another day. Want to get this thing rolling on it's own power.
