From what I understand all the 42,43,44s are the same injectors -- it just depends on who does the measuring.

 

My flex fuel 5.3 had 28's. Don't bother with washer fluid? So where do you get straight meth?

 

I've got the marine's and they are 42's. Just about any race fuel shop but i'm in alabama fixin to get my kit. Down here there is a place at the state docks that has it. A friend of mine said he could get me about 5 gallons a month for free.

 

You can usually get meth from whoever sells serious racing fuel in your area (not at the track pump, but a place where you can get a barrel or a 5 gal drum).

 

Thanks for all the tips Berserker!

 

Also, gocart parts racing stores, some speed shops and stock car dirt racing tracks generally have the stuff too. Your best bet is though bulk oil and fuel distributors, like TB says.

 

Cool, there is a dirt track race shop within a mile of my house and two dirt tracks within two.

 

Ya a lot of dirt cars run on Meth

 

didnt know that. thought the marine 42s where only 42s. i know the SVO 42s are 49s

 

These are the spec's on the 8.1 MARINE injectors...

Part Number 17113739 (OE Part # 25176061)
Direct fit for short G.M. LS1 SUV injectors
Static flow @ 37.95lb/hr @ 43.5PSI / 300KPa (4.31 g/s = 398cc/min)
Static flow @ 43.82lb/hr @ 58PSI / 400KPa (4.97 g/s = 460cc/min) *
Dynamic flow (2.0ms/10.0 ms(pulse width / rep rate)) 6.0 lb/hr @ 43.5PSI (0.748 g/s @ 300KPa)

The SVO injectors (car injectors) are rated at 42lbs/hr @ 43PSI (3bar) fuel pressure making them about 49lbs/hr @ our 58psi (4bar) fuel pressure. I hope there is no more confusion about this
