injectors for a S/C engine

[aleborjas]

hi i whant to know what size of injector do i need for a 4.6 stroked to 5.0 with a vortech with 16 pounds, P51 intake, 75mm TB, ported heads with bigger valves, comp cams 278 cams, long tube headers, 2.5" X pipe and 3" aftercat, T56 trans, 3.73 gears, lightning maff, dual intank fuel pump, aueromotive complete fuel system with return...
The cuestion is what size of inyectors do i need and with what fuel pressure do i need to work with, for my combo?

Go with a set of 55-60lb 'ers to support your fuel flow needs and only a dyno tune will tell you what fuel pressure it will need to be run at. I would suspect to start with though....40-42lbs is what you're going to start with.

Siemens-Deka 60#'s would suffice
but 42's would be cool as well

I'd do 60's. 42's won't be enough.

i whant to boost 20 pounds now i just receved my new supercharger YS vortech i used to have 16 Pounds but today i decide to get more power are 60 pounders ok for a stroker? and which other good brand? remember i have the stock computer tuned by Diablo Sport.
can my head gasket supports that? i have ARP studs...
like how many RWHP's do i have with this engine? and like what time on my ET's? the car has stock weight!

Siemens-Deka are really the only brand I know of, personally, that has worked well for others. And the type of injectors have nothing to do regarding if you have a stroker or not. Cometic head gaskets might be a good idea from Livernois Motorsports. Go to the dyno/track for the rest of your answers.
