24lb injectors for stroker

[HossHoffer]

Anyone have a good resource for injectors? I've been doing searches all night and feel I could do better price wise. Seems to be around $80 a pop unless I get rebuilt ones. TIA

I bought mine off of ebay for $65 for a set of 8. They were pull offs from a Mustang.

Better off getting some 42lbs and getting an AFC to throttle them down.

I hate to say anything but the 24# injectors are even a bit much at this altitude. Why would you want to get 42# injectors?

On a stroker, the 24lb injectors would do fine at any altitude. The MAP sensor automatically sees less dense air in the intake manifold at higher altitudes and shortens the injector duty cycle so the engine will not run too rich.
If you use smaller injectors at high altitude, they may work fine at that altitude but as soon as you come down to sea level, their duty cycle will be maxed out and the engine could detonate because it's running too lean.
I'm using Ford 24lb injectors in my stroker with stock 39psi regulator and a MAP adjuster set at 5.15v (2% enrichment). A/F ratios are right on the money and emissions are excellent.

Thanks Tom. I've been scoping out e-bay but there must be a lull on injectors. I think I'm going to have to just fork out the $$$ for the new ones. Jesse is now working for Rickenbaugh Cadillac so might be able to get a good discount.

Edit. Tom, do these look like the right ones?e-bay
Did another search and there they were :confused1

fiveomotorsports.com got my #19's there a couple years back and at the time was one of the best improvements I had made on the pig.
