Should have bought my Darts they were awesome on the 402 they came off of and the runner would have been plenty I am sure. If you do deside to maybe swap those heads out I might be interested in them for my LS1

people have made 390/400 on those same heads and a mid sized cam on a 5.3, let alone a 370. You should be at least 400. Elaborate more on your injector issues...what size are they? It sounds like you ran out of fuel up top

i was not there. but he told me i need some bigger injector "mine are done" he said. LOL max out a 112%, the 225 fuel pump is good he said but i just need to find some 42lbs injectors. They are 5.3 59cc PRC 2.5 heads. i was a 10.2:1 with the stock 72cc and a .40 head gasket. i hoping i can get some 42s and get a little more out of it.

what ya think

thanks for all the fast info

running out of fuel causing a lean condition will cost you hp. find out what the run was taken to and how lean its getting

i missed the injector issue in the original post. which injectors are you using? my stock truck injectors were at 110% idc on my 220 cammed 5.3. that is probably most of your problem.

yes yes yes....they are the stock one that cam on the truck. i was told i would not need them but i was thinking all the time that i was going to need them. so im posted up on the parts for sell to try to find some.
