Nice job. Looks like you had to totally sink the radiator into the support which is what I expected when you said you had the engine all the way forward. I'm working on a swap with a tight engine compartment (a ZR2) with a 5.7. The 4wd setup makes things really tight on the ds. Are you running your fans off the 0411? I'm assuming that's the drill. What are you using to do your tuning with? Did you keep the 5 speed for another project???

 

I have a 01 ZR2 Blazer and am currently putting together a list of all parts for the 5.7 swap like you're doing. Would be interested if you have a "thread" somewhere that outlines any struggles or major issues or "I wish I would of did it that way" type nuggets.

 

I currently have the factory 4.3 411 PCM in my truck reflashed to the 5.3 setup and it runs everything including the electric fans. I have the Current Performance 411 PCM sitting on a shelf as a backup. I use HPTuners with an AEM wideband to tune the truck.
I actually sold the factory engine and transmission for $600 after i did the swap. The NV3500 is an ok trans for low power and for a truck, but the ratios between the gears are terrible for racing and they are a bit weak when you abuse them. I also like an auto for racing.

 

How long have you been doing tuning with HP???

 

I have only tuned this truck. I am no expert with it, but i can get it running nicely and correctly. It just takes me a long time versus how quick a good tuner could do it.

 

Going LSA, I don't know if you are still worried about your intake. Looking at photos of your engine bay. I think I'd take a look at moving the battery to the back. That corner looks less cluttered compared to the driver side. You might gain access to the fender metal in which you could open it up to pick up fender air. If you cut the opening nicely, you can split a piece of vac hose and push along the edge. Will give it a cleaner look to go with your build. Awesome job on the project.

 

No build thread for mine. Once I get everything ironed out I'll probably post a build thread on it. If you need help I'll do what I can to give you a hand but my build is a truck, not a Blazer.

 

Did the airbox bring temps down? Keep us up to date! This would be a fun project, but knowing me I'd get pissed and jump ship very quickly. Also never done transmission work before (let's hope it stays that way haha)

 

The airbox brough my Intake Air Temps down about 30 degrees in the Texas heat.

 

Still need a few more parts, but its almost time to start the next phase of this swap. HAHA
