Sorry it has been soo long since I have last been on, I just got back from my military training not too long ago. I know this topic has been beat to death, but currently I am having a 383 built with vortec heads and a comp cam (I don't have the specs on it right now, but will post them as soon as I can). When I last talked to my builder, he said that this particular motor he is building for me will make about 375-395 and he as gotten as high as 425 hp out of it. I tried to search the forum for some advice on fuel support for this motor, but either my computer is being retarded or the search box is currently inop. What I have been able to find is that while you can get the 454 tbi to support those numbers, you will run rich at idle due to the injectors not being able to get the pulse widths low enough to remove enough fuel and still have enough fuel for your top end (if I understood red94chev's post correctly as found here: http://www.fullsizechevy.com/forum/general-discussion/performance/tbi-tuning-87-95-obd-i-ecm-pcm/373201-400hp-carb-tbi.html). I tried looking for the edelbrock 3502/1 and could not locate one for sale. If anyone has any alternate solutions that will not break the bank it would be appreciated. And if I am just completely retarded please point me in the right direction, thanks for your help
