They will support allot of power, you will run into allot more issues before you max them out... From everything I have read, seen,expirenced the 60lb siemens are a better injector then the 50's, 57's etc. Due to there response time. Basically in a nut shell they can pulse lower and the lower the better. They wont pulse as low as the 43lb truck injectors but for there size they are very good.

 

Ok, I guess i'll just take the plunge and purchase them soon. Seems like they'll be plenty big enough for my setup. On splicing them, i will just have to splice into my old wires because these arent plug and play correct? Will i need to lengthen my wires and raise my fuel rails?

 

If you wanna cut and splice....here is a good write-up for the small blocks...

Alright thanks. The "Gm installation kit" that you can buy with the injectors from nelson, do you know if that comes with the pigtails also?

 

Dunno...

Seriously though, the "installation kit" I cant imagine is anything more than connectors, spacers, and rail bolts. Bolts are like $2 and 1/2" aluminum tubing is like $1 per foot at the hardware store....just need to cut it down to 5/8" lengths. The local ACE Hardware near me had aluminum spacers already cut from 1/8" up to 1" in 1/8 increments.....they were like .33 cents each. Not sure how "handy" you are but every thing you need other than the connectors is only a trip to the hardware store away. If your gonna cut and splice, get the connectors from summit for $15....you can do the whole project for $25 plus the cost of injectors.

EDIT:
LOL....just saw the cost of the kit from Nelson's site. It costs a lot less than i thought.....so maybe the kit is not a bad idea. Still not sure about the pigtails though.

 

lol, the installation kit doesnt seem to be too pricey, so im thinking it probably doesnt come with the pigtails. I wonder if these injectors would work with a victor jr?

 

Ya they will.

 

With the same mods im assuming?

 

Youll still have to change the plugs on the harness however I dont think youll have to space the fuel rails but I dont know what fuel setups are available for the victor Jr. at the moment. Making the spacers and all that crap is easy, there is not much too it.

 

I'll try to look around for Vic's, and info's on peoples setups. Did you all get your injectors from nelsons?
