I use Amsoil 5w30 Signature series and Amsoil filter. Strange how they told you to use that race stuff

That’s awesome! Great numbers for a cam swap. So you didn’t put that crazy intake on? What lifters and rods did they put in? How does it pull off the line? Up top?

Waiting is the hardest part, lol. Just looked up those parts. It’s almost $5000 for 2 fuel pumps and a set of injectors… yikes

6k for a fuel system upgrade... that's insane. I know parts for our trucks are expensive but wow, outrageous. Hooking up is a problem. It makes sense to set up your truck like that for racing. 7000 RPM shifts! I can't wait to hear what that sounds like. Going to be an awesome truck!

I'll assume the DOD delete cam in the graph has the stock lift. It makes 450 ft/lbs from 2000 (with headers and E85). With your setup, heavy tires and a level, you'll be sluggish off the line with the MSD and cam. It doesn't make 450 until about 3000, and it makes the least peak torque. The MSD intake is $2300 for 47 HP peak, and it makes it above 6000. I have upgraded push rods and valve springs and I shift at 6100. If you want to spin faster you might have to upgrade everything in the heads. A Circle D converter is $2100. It will make your truck feel better off the line and go faster in a race. They will have the engine out already, it's not going to cost much more labor to put it in. If you are chasing numbers go for the torque. IMO getting snapped back in the seat from a stop is more impressive than a 60-120 roll.

I only saw the one for the Vette, part #2700. It will probably bolt on and work, but it’s going to kill the bottom end torque. The only gains will be at 5k and up. Not very daily driver friendly. Call Davenport and see what they think about it. If I were you I’d save that money for a converter

It’s not very often, maybe once a month if the tranny downshifts funny. It’ll do one lurch forward. I just mash the brakes harder, lol. In 6th gear at 6100 RPM I’ll probably be going 180-200 Km/hr. The driveshaft might handle that RPM but the tires are not rated. Just safer for them to dyno it in 4th and do the math after.

They are good. If you can afford it, get an aftermarket converter with a slightly higher stall than stock. The only issue I have is when I’m coming to a stop the cam will push through the brakes. Not every time, but it’s pretty sketchy on a slippery snow day

No, tuned for 91. E85 is hard to find here, only one station in the whole city has it. I have full custom exhaust. 1-3/4” Kooks headers, kooks y-pipe with high flow cats then it duals into 2.5” pipes with Dynomax mufflers. Loud AF. I’ve heard that the Magnaflow 12909 muffles headers good. This is the dyno sheet. They said it was a 4th gear pull, and it would have 5-7% more power if it was done in 6th.

I have that cam in my 2018. BTR makes quality stuff. With headers it added +100 hp and +80 torque. I don't notice the tiny loss of torque below 2500. After 2500 it takes off like a rocket. The idle chop sounds so good. Been trouble free for 30k km

I have Belltech 25004 struts on my 2018. They do use the stock coils. They ride better than the factory Ranchos and have lasted 40k miles. Nice truck!

Taking the resonator off will cause some droning. Removing the 3rd cat will make it slightly louder. If you are doing it yourself, add the Carven first. If it’s not loud enough remove the cat. Still not loud enough? Remove the resonator. If it’s a shop doing it, take everything off and add the Carven. Worst case you have to put a resonator back in. I have 1 3/4” headers with race cats and custom dual exhaust. It’s loud as heck, but I love it. She drones like a queen bee, but not at a frequency that bugs me. We have taken it on a few 12 hour drives. Wife loves it

I have a chunky cam in my 6.2L. It’s easier to do the cam with the engine out of the truck. Then you have access to the converter as well. Sounds like you need to change it any way. The cam will burn more fuel. More power = more fuel. I gained 25% more power and it burns 25% more fuel in city driving. On the highway it’s better, but still uses more than stock. I get 18L/100km city and 11L/100km highway. 13 mpg city/ 21 mpg highway. It is fun and sounds mean. Worth it

Ordered this thermostat from Amazon. Came in this unmarked box just raw dogging around. They couldn’t even bag it. It is stamped with the GM logo and the correct part number. Does this part look like it’s AC Delco, or some cheap knockoff?

Stock opens at 90 C. Something is wrong inside the tranny. Most likely torque converter, like you said. If the fans came on and it cooled off, then the bypass valve opened. Just opened too late for some reason. 150 C is way too hot, you probably cooked all of the seals. Probably gonna need a rebuild. If I was getting a rebuild done I would put an aftermarket converter in. They are built better. Also get the 70 degree TBV
