Default more power

this is going to sound stupid, but i was wondering if any one could give me a power estimate on my truck due to me not having the availability of a dyno. the truck is straight piped, cold air intake, star wheel 1 full turn, fuel screw 3 turns. the truck is an auto with 518. stock 3.54 gearing. any estimates would be nice! thanks!

it depends on how well the trans is holding. im not very knowledgeable on how much 3 turns would be on an ol ve truck, so here is a bump

280?! 300?! You are way over shooting your numbers. He's a good 215 at the most.... These trucks were around 175 from the factory depending on intercooled or non intercooled. I cant remember the non intercooled numbers.

Hey guy's 160HP from the factory. jdbigblue should be about 250HP with what he has done. Remember the tourqe on these old one's are way better then newer trucks so you can twist tires with 275 HP.
