30lb injectors are too small.. Even 36lb injectors are pushing it to the limit at 450 horsepower.. Better safe than sorry, I would go get the 42lb injectors..

I used a 90mm LMAF I picked up from a buddies shop. 42# injectors I got from BOI. http://www.blueovalindustries.com
I did have to add Diablo Mafia because the LMAF pegged during the dyno tune. If you havethe funds look into an SCT MAF.

Since you're na and still making under 400rw the 30's are still goods anything over that would be 36's and above. Wish I could remember the link to injectors sizes for NA motors vs power adder.

remember to use horsepower at the motor, not at the wheels.. [ 2014-09-12, 05:55 PM: Message edited by: Blow_U_In_Reverse ]

A lot of guys use the Lightning 90mm maf's because they are a good deal ($180 or so) but keep in mind those mafs peg at around 400 to 430 rwhp.
I had one but it was pegging so I went to a SCT BA2600. These are a direct swap for a lighting maf but are good to 600 rwhp, they cost around $230.
These are pretty popular mafs so most tuners already have the transfer curves for them.

Thanks Boss 327 36 lbs is more than enough for 450 rwhp but Im going with 39's or 42's just to keep more hp options open! No such things as to much hp lol
