No. But I would go with 13077 i think the part # is. Heated 02 for a ZR1. It will fit.
I didn't know SLP made 1 7/5" headers. That's a lot of low end torque baby!

Ryan,
Thanks for the part #. They are 1.75", or 1 3/4". Planning on using the stock 22# injectors. Will there be a problem (please just say no, I'm out of $$$)

oh ok. that 1.75" 1 3/4" threw my slow butt off.
I'd like to say, yes the 22#ers would be accurate but I'm not sure.
My friend, Josephandres, has a 355TPI. He has all bolt ons and runs 14.4 in the 1/4. ZZ9 cam, TPIS big mouth intake manifold, 1.5 comp cam roller rockers, stock heads. He has blueprinted and balanced Bosch 22#ers. We just had his car dynoed this past week. His dyno run looked like a freakin upside down "U" He made a lot of low end power, but at mid/high rpm range his car fell on it's face. Can you imagine with all his mods, he only had 186rwhp! The tuner bumped up his fuel pressure from 49psi, to 62psi and he got the rwhp up to 219. He doesn't plan to run 62psi too long because it will kill the fuel pump, but I can tell you the car is a hell of a lot faster. The guy recommended he get Ford SVO 30lb injectors, which he did. $219 from summit. The tuner also said my friend was out a good 60-70hp still because of lack of fuel at WOT.
But if you want to save money, I say after everything is together (heads/cam), take your car to get dynoed. They will be able to tell you what kind of prom tuning your car needs. I hope you didn't forget about the prom
More than likely, they'll tell you to go with bigger injectors. Maybe have you tell the chip burner to lean you out at low RPMs, and richen you up at WOT. But we'll see. They may be able to just increase the pulse width of your current injectors , run HIGH fuel pressure and get away with it.
Trust me, do the dyno run after everything is together. It's better than playing ping pong with your prom burning company. Just FYI, the dyno run was $125 for three runs. Another $175 for tuning.
If you're running 13.9 now, you're going to be hauling some a$$ with the cam/heads. Holy crap.

I found someone local that is going to work with me on burning a prom. I talked to a Corvette owner Sunday at an autox. He has the exact setup I am putting together except it's an L98 C4. He has 24# injectors but felt they were probably not necessary. I may be wrong and don't know the right terms, but it seems to me that the smallest injectors that provide enough fuel at the maximum acceptable duty-cycle would make the most power. I'm thinking that the longer spray pattern will help keep the fuel atomized. This is more important on our back-fire injection (as compared with sequential).

yea i agree with you on the injector cycle. Higher FP is better (of course dependant upon injectors), but not to high. Nothing over 47 I'd say.
However, it will be ALOT easier to swap injectors out while you have everything off the car anyway. Think about that one
Theres a guy selling ford svos on thirdgen.org classifieds. Or maybe it was fbody.com classifieds.
Brand new for $150 shipped. Give him an email.

Just give me $150 Ford parts, what you talking about Willis? Actually, I will consider it. Pulling the plenum/runners is a lot of frigging work! I am waiting til I get roller rockers and everthing before a wrench gets turned. I want to do everything at once. I figure I need a lot of time to port/port match everything. I am hoping to get into the 12's with the addition of ZZ4 heads/cam, Accel base/runners, SLP headers, roller rockers, !CAT and !AIR. I am going to see how the stock TB works also. I know of plenty of LT1's making 300 rwhp on a 48 mm TB, and thats about what I expect from this combo. The 13.9's & 14.0's are from the killer 60' times it is cutting. I have yet to run 97 mph in the 1/4
