Hi, I have a 383 that I put in my 92 camaro that had a 305. I am using my stock computer with my stock intake and TBI. Right now I have my return fuel line clamped off so that the pressure is better for the new engine. I am fixing to replace my stock fuel pump with something a little stronger. I want to put a better throttle body and intake on to feed that 383. I called Holley and they said that the stock computer will not work with one of their pro-jection TBI's. There has to be something I can do to keep the fuel injection w/o going to a carb or tpi. I cant afford tpi. Wish I could. Now from what I understand the fuel pressure regulator is on the throttle body itself. Is there any way to replace the regulator or increase the pressure? Can I also increase the size of the injectors? I was going to shave the shafts and increase the bore size and do the same on the intake. If I do this will the computer still function properly? Any advise on what you guys would recommend doing if you were in my situation would be GREATLY appreciated. Thanks Danny

 

Just get the 502-6!

 

Thats stupid. Good thing your planning on replacing the stock fuel pump, because you will burn it up. Waste really as the stock fuel pump will probably be ok for now.
Get a 670tbi with 85pph injectors and a nice dual plane carb intake with adapter. Then swap in a custom chip.

 

Hey your like the first person that ive found that is have way close to where i live. I live in paragould AR. it's about 3 and a half hours from st-louis

 

lmao, what does that have to do with the subject?
Just PM him.....lol

 

I can't find the part number for jegs. They have like 3 different ones. The 2bbl the 2X2 and another 2X2 and I dont know which one I need. And also which intake will I need. THanks Danny

 

Easy! Read my sig!!! Even has the TPS connector you will need.

 

I will throw my $.02 in as well. WINALDL

This little tool will aid you in adjusting your fuel pressure to meet the demands of wide open throttle at max rpm. Then you can either use a VAFPR to make it happy at the bottom end of the scale and/or provide the WINALDL sensor datalog to a custom chip burner for burning a new chip. I recommend the and but it "may" run ok with just the VAFPR. Only WINALDL knows for sure. It may cost you $150 to set it up but will save you at least $1000 worth of headache.
