I think you are ready for bigger injectors and MAF meter. I would also throw in an adjustable fuel regulator. I actually think the car will run stronger.

However the most important thing to remember when porting your hood is to not take to much off the front....

You could go to the 24 # injectors now, especially if you are getting a new MAF that is calibrated for them. But, I don't think the injectors are a necessary upgrade for you at this point.

Many people upgrade injectors earlier than they need to. I have a very similar set-up to yours with the B-cam, 1.7 rr, and GT-40 heads and intake. I am making the numbers shown in my sig with 19 # injectors. In fact, we actually had to back the fuel pressure off to get those numbers.

If I am not mistaken, many tuners say the 19 # injectors will support near 300 hp. Someone correct me if this seems wrong....it has been a while since I have given thought to it.

hey if you could post all of ur mods.. what gears do you have also are they x-heads? what does the bad boy run?

Here are my mods:

GT-40 upper and lower intake
B-cam and 1.7 rr
GT-40 iron heads
70 mm TB
75 mm MAF ( I think this is right...I bought it used and can't even remember if it is a 73 or 75 at the moment)
Shorty headers (Equal length...also bought used)
K&N conical filter
190 lph fuel pump
adjustable FPR
pulleys
3.73 gear in the back

I think that is it. Unfortunately I have never had it to the track. Every summer I I say I am going to go and I never make it. I guess I need someone to go with to show me the ropes the first time
