The intake manifold should be good for a few tenths . I see 11’s in the future

I know for a fact aluminum accessory drive pulleys will knock off a tenth. Let me see what i can dig up for you, cause my coyote stock buddies might have some pulleys laying around. The coyote stock class doesnt require accessories to be driven now

Spent my morning getting the Gt350 installed. Took dozens of pictures and will compile them here later.

I need to know what water pump pulley is on your truck, 3bolt or 4bolt. And take a good picture of your alternator pully.

did you get a chance to look at the filter
just asking some mechanics will use any excuses to CTA
and blame a part not themselves

as long as they made it right its good

No but if I had to guess, the other guy didn’t oil the gasket prior to installation.

GT350 install process:
1. Disconnect fuel pump relay connector above the fuel tank.
2. Second step was to start the truck and let it stall. This was the easiest way to relief fuel system pressure. It obviously ran pretty rough and I couldn’t resist a video. Afterwards, I cranked the engine for about 10 seconds to ensure the pressure was relieved.
3. Disconnected the battery.
4. Removed the CAI, evap purge solenoid, disconnected both (high/low pressure) fuel lines, disconnected the fuel injector harness and pulled the PCV hose.

5. Disconnected the fuel rail pressure sensor.
6. Disconnected the MAP sensor.
It was more awkward than this picture suggests.
Figured out putting a floor mat over the hood latch made things more tolerable. What you don’t see is the 6’ ladder I was using for access.

9. Preparing the GT350 intake for installation. First was drilling the upper left throttle body hole to alleviate a misalignment issue.
Here is a good comparison of the two intakes. The truck intake has much longer runners than the GT350 and is testament to the great low end torque it offered. This era of truck doesn’t use IMRC’s and was quite rowdy down low. I’ll inevitably lose low end torque but the top end will be excellent. Given the fact I have a 10-speed, low end only matters for a moment.
Here you can see some of the modifications needed to fit the Gen 4 fuel rails to a previous generation intake.
Notice the stock intake has built in spacers.
Thats where these copper spacers come into play.

Next was drilling a hole on the back of the intake to mount the MAP sensor. I gave it a small bead of blue RTV to ensure a proper seal.
10. Dropped the GT350 intake in place, installed the fuel rails and torqued everything down.
11. Cut the evap purge solenoid hose and replaced the front section with rubber hose. You can see the previously installed evap block off plate.
12. Made then installed a new PCV line from rubber hose. Connected the battery, primed the fuel system to leak check and fired it up! No leaks and no CELs.
13. Got everything set up to datalog and hit the road.
More to come!

man that seems like a lot of work for an intake with the rails and all.

For an additional 30+ hp and another 500-600 rpms? Worth it.

Dyno appointment set for Monday @ 1600
Tuner wants to fine tune the truck and then compare the difference between the stock airbox and the whipple box.

Looks like fun! I found that an old or cheap pillow is very easy on the chest! Haha
