I think that sounds like a good plan, Chuck. You have enough stall to be happy with moving the rpm range up six or seven hundred. You'll definitely want an intake with that many cubes if you're going to turn in that hard and the R is a good choice.
The GT40 works fine with boost and a mid-5s top to the rpm band, but that many inches and rpms, it's beyond done.

Do you have recommendations for intake? Choices are (?) the Edlebrock Victor, TFS-R & TFS Box-R, and Holley Hi-Ram. The Victor's runners seem to short, the Box-R Seems designed for blown or High rpm, same for the Hi-Ram. The TFS site says for the TFS-R use the 75mm version for 1500-5500, and
the 90mm version for 2000-7000rpm. Which would I want? My MAF is 75mm.
I currently have 30lb injectors, for 500hp I think I need more like a 39lb or 42 lb, correct? If I kept the existing MAF (PMAS) can it be recalibrated for larger injectors, or best to replace it?
If that performance shop has a good reputation then just take the truck to him and have it all done. That way if any connectors, wiring, etc,etc are not right or other items you're not running back and forth between two shops each pointing the finger at the other. Rather than worrying about RPM at the moment I'd focus on what you want out of the truck. I believe you want a fun street truck, and to me that means getting parts that make good responsive well behaved low end and mid range power.
I want a fun street truck that will also turn respectable ET's at the track compared to modern cars. I imagine, and I hope you will correct me if I'm wrong, That unless I do something crazy this large of a motor with a long runner intake will still make good torque in the low to mid range which would make it fun on the street?
You make a great point about the 2 different shops doing overlapping work. I hadn't thought about all of that. The Speed Shop owner is going to send me a written estimate for doing everything this coming week and we'll go from there. I'm remembering VERY quickly how expensive this hobby is! :blink:
What I'm thinking of now, to partially redeem myself
, is I'll do all the tear down (down to the long block) and reassembly (intake, wiring, plumbing), but will still have Shop B pull and then install the long block and headers since that is the part I don't really want to deal with, and they are literally 3 miles away. Or, I talk the wife into going along with putting a lift in the garage, hmmm? :headscratch:

Where is a good place to find used parts like intakes, injectors, etc? eBay seems all but useless now.
