im not sure what size injectors i should run with im buildin a 355 cc 276hr14 cam cc roller rockers cc roller lifters 58mm throttle body k&n intake true duels headers any info would be great thanks guys

 

id say 36lb but some others may say like 42lb.

 

Yeah I went with 42lb, im not sure of the price difference between the two, but if he gets 42, he will lots of room to grow.

 

30s will be fine, but maybe I'm biased.

 

I agree it sounds fairly mild so 30`s should be fine.I dont think you need 42`s till around 500 fwhp anyway

 

Appears to be cam only, not ported heads. That would limit flywheel HP a bit.

Rather than guess at the injector size, try this. Multiply the expected flywheel HP by 0.07 to get the minimum recommended injector size. That factor assumes a moderately efficient tune (0.476 #/HR/HP BSFC) and a maximum duty cycle of 85%.

Example....

500 flywheel HP x 0.07 = 35 #/HR

 

its got all the bolt ons full cc roller heads have just been redone valves springs retainers so on headers 3" true duels 58mm throttle body im wanting to port the heads and intake myself is this hard to do and is it smart being i just got them redone? there not even on the motor yet also with the injectors i want a lil room to go such as super charger some day..thanks
