are 30lb injectors good enough for LT4 conversion kit or should I go with 36lb?

 

30lb is just fine.

 

how much hp are the 30lb injectors good for?
Are the Accel injectors good to use?

 

When you're talking about LT4 conversion... Are you talking about the LT4 intake, LT4 cam (hotcam?), etc?

If so, the stock injectors will work fine to around 390-400 rwhp, which isn't even close to what a "LT4 conversion" will give you.

bored .030 over, LT4 intake, LT4 hotcam, LT4 heads, hooker LT's, hooker y-pipe, cold air, crane ignition, 58mm TB

 

I tend to think that's pushing it a bit. The general rule is it you have to go over 80% duty cycle, you need bigger injectors. Can't remember who but someone said they are using stock injectors in a 383 with like 370 RWHP and runnig a duty cycle of 90-95%. Thats too high. I'd be safe and get bigger injectors.

my 2 cents worth

 

My guess with the LT4 "conversion" is 350-360ish rwhp. I think injectors won't be necessary.
