Default 427's chime in please???

I'm running the Ford SVO race injectors now, suppose to flow as much as GM's 36's. So what are you guys running and do I need to step up since they are the same flow. I'm thinking of going hydraulic, but would there need to be a change if I stayed solid? Any other advice is appreciated. Thanks

I run the same in my 424. Work great still have room if I go to a bigger cam. They would fall short if you go with a blower but for NA they are good.

It's all about the HP. The 30# injectors will make it to 600 RWHP NA. And yes, they flow like 36# injectors when run at 60PSI fuel pressure.

So if I get to 550 hp and do 200 shot of nos every so often, what injector would be recommended?

Here's the formula for calculating injector size:

Expected flywheel horsepower multiplied by .5, divided by the number of cylinders, multiplied by 1.1

Example 400hp x .5 = 200
200 / 8 = 25
25 x 1.1 = 27.5 or 30 lb per hour injector

BTW I talked to ERL this morning and they said my block should be done by the end of the week and if it is I'll be going up next Wednesday so I can drop your block off then
