with modern vehicles [obd2] there are other things at play that you don't even notice that has a huge effect in the driving experience, torque management, shift points... a simple tune can change a vehicles behavior so dramatically that you may find you don't really need all the extra stuff to be happy with your rig. have you tried that yet? you'll need one after you build up your engine anyway.
Right now Ive got headers and an SCT tune on my 01 sport. Its enjoyable to drive, just have a need for speed, especially since a childhood friend of mine just dropped a vette engine in his S10 haha

I just went and bought a truck with the V-10. MUCH more power than the 5.9.

I have a hunch that by the time Id realistically be able to comfortably afford an engine overahul, I'd probably just buy a newer, more gas friendly truck with 4x4 xD

But maybe I'll just get something fun to drive on weekends or something haha

I've got an 01 1500 Sport 5.9 That I'd like to really get up and moving a good noticeable bit faster. What mods would I need to see these kind of numbers, so I can get a general idea of the price. Being streetable, I'm not looking to completely kill low end torque off, and make all my power at strip only RPM's, Show me that nice mid-range.

Also I know I'd need a beefy trans to even hold this amount of power, what would a trans overhaul to support this power level look like?
i have a set of Magnum R/T heads that my engine builder says are just as good if not better than the EQ heads. they are double quench closed chamber heads. i need to get my post count higher to list on here but i have them listed everywhere else with some interest on intake and a low ball on heads. trying hard to rid myself of all stuff i dont need so we can go circle track racing

What bolt pattern are those heads for? The LA style (angled), or Magnum? (straight down.)

I was just about to look for this article. A good cam, new heads and a custom tune and you could keep the efi setup and pcm. You'd be looking around $2500 but for 150+ hp that's really not bad for not having to tear into the bottom end.

I know it's not the advice you're looking for, but, you could go buy a Hemi...... I think lowest stock number is supposed to be 345HP, much closer to what you're trying to do

idk we took a 360 stock swirlport non magnum heads, cast iron intake and exhaust manifolds all the way to 370hp with no modifications on the dyno 500cfm carb. with the R/T heads and MP manifolds and headers we were expecting to be at around 450hp. too bad the chevy heads and performer intakes for the chevys got them to 530hp. i just could not compete. thats why we are dumping these but for anyone looking for EQs id go with this package.
