FAST intake on 5.3 heads - stock cube LS1?

[flattop]

Take a look at injectors from a Grand Prix GTP.   They are ~35 lbs at 42.5 psi, and ~40 lbs at 58 psi.   You can get them cheap, also. 

Are these injectors tall (LS1) or short (LS2/LS3/LS7) ?  I am considering running them with a FAST 90 and an LS2 fuel rail.  The shorter injectors will not allow my fuel rail crossover to clear the FAST.

GTP injectors are tall (LS1/LS6).

FYI on your calculation, you should use flywheel HP not RWHP... I found this out when I was trying to size injectors.  Use a correction factor of 1.15 for manual transmission

Good catch, when I called my tuner he went head and had me get 42lb injectors. I decided to just call and ask after realizing some tuners already have their own good tables made for injectors they prefer to tune with.

so did you decided to get the FAST intake?  are you using an aftermarket TB or are you going LS2?  are you expecting any fitment issues with the hood or firewall?

Nope. LS6 Intake Ported stock TB and 42lb injectors. Tuning date is Dec. 3rd and someone is flying in to buy the car on Dec. 8th. I'll post the dyno results, but won't get a crack at the track or anything before I deliver the car to the new owner. Pretty much putting the car cover on and calling my swapping days over.

Tiff's pregnant, my house isn't big enough and I'm currently driving 200 miles per day to get to work.

At least my mortgage broker guy is excited....
