okay, i'm down to the last bits of my engine build and need to know just two more things before i'm done.
1. What size throttle body should I use (52mm, 58mm, 54mm (seen rebuilt 54's on ebay))
2. What size injectors shoud I use (have both stock 22# and a set of 24#)

Now the Mods: '91 b4c (police) camaro L98
HSR intake, MSD 6al ign., procomp 2.02 1.60 alum. heads (265cfm @ 28"), crane powermax 104224, short tube headers, AIR and EGR delete, 500 over stock convertor, 3.42's, 1.5 roller rockers, etc. etc.

pcmforless is tuning my computer (using dataloggin) but need a baseline chip....and need to know what you think...

my idea was 52mm TB and 24# injectors.

 

How many rpms you plan on spinning it to?

As for injectors. You need to use the injector formula, putting in an estimated hp based on airflow, then calculate out.

edit, here is the formula, partly worked out...

lb=(hp x .5)/(6.4)

 

The GM Ramjet 502 comes with the TPI sized 46mm TB on it and makes 502 HP. IMO, I wouldn't run anything but the stock TPI throttle body.

 

i don't know what HP i think i am running....as for RPM cam is good for 5800 so 6000 max.
