416 ci (4.065" bore x 4.00" stroke), 13 to 1 compression, race heads, big cam, sheet metal intake, naturally aspirated, etc. What size injectors? Thanks.

I have no clue as to what kind of power it will make, but given the setup, what do you feel is a good injector brand/size?

would at least start off with 36 pound or 42 even-

i have made 540-550 rwhp on 36 @ 75% duty cycle-

hope that helps-

I used to have a set of SVO 30s, which at our fuel pressure would be 36 lbs. I figured they weren't going to be enough so I sold them.

good move-

42 will be more than enough-will even support more if u want to do more mods in n/a trim

what power u looking at with that comp ratio-it should be good-

What kind of power FWHP/RWHP does the 42 lbers support? I have no clue as to what I'll be making. My drivetrain eats up a lot of HP. Big stall, no lockup, 3 speed, steel driveshaft, 12 bolt, 4.56 gear, 30" slicks, etc.

I used to run the green top 42's (About 49.7lbs/hr at 58psi fuel pressure) on my 13:1 417ci, with the top-end power robbing lsx I made 504rwhp sae through about the same drivetrain (th350, no l/u, 9", 35 spline axles, 4.11s, 30x10.5 radial slicks). I was running in the 83% IDC range. Now I don't have injectors anymore

Drag, I run 42's on my car and you know what I have. They should be plenty!

I've got 8 more cubes and a few more points in compression too. Not to mention fully ported race heads. I THINK my setup is making a little more than yours. Just messin' with ya. I already ordered the 60 pounders. I have room to grow.

On a similer setup I opted for 50's. 60's shouldn't be a problem with that beast though.
