Dyno Day! For no other reason than curiosity, I wanted to see where this old girl would perform, in basically all stock L92 form.
Guesses on HP/TQ? (Stock cam, truck intake, Cold Air Intake, LS3 Exhaust manifilds, 4l80E, 2 1/2" exhaust, 12 bolt rear end)

What do I win??!!

I admit I cheated. I just found a stock tuned Denali dyno chart. You should cam it though, it will be a whole different car without much downside other than cost.

Haha, nice!
I'm toying with the idea of throwing a few more performance parts at it, but then trying to reign myself back because it's dead reliable as it is.

Thinking Long tubes, a converter, and then a cam, in that order... If I decide to take the plunge.

Yep! I already have a good trans cooler, so I'm good to go there!
Just purchased headers too. Stay tuned!

I took a chance and found a set of cheap long tube headers on Ebay. 1 7/8 Primaries and 3" collector, in stainless steel. They fit perfectly, and dont hang down too low! The car is getting tuned now!









I shortened each one of my plug wires so they were the perfect length and running close to the block. For extra insurance, I put the heat wrap socks on them as well, even though there is good header clearance. I think it looks nice and clean too.

Just pulled the car out and took a quick little vid outlining some of the things I've done to it recently. I'm looking forward to driving it all summer!

itching for summer myself. Sick of seeing it sit in the driveway. I thought you had 20/18 wheels...those look like 18/18, no?

Yep, I did have 18/20 but I changed the rears out for some 18x9's. I wanted to get a little more meat on the tires, so I'm now running 45 series all the way around.
Chalk that up to me getting something just how I want it, then switching it up.

I also changed out the air ride for double adjustable coil-overs. I can never leave well enough alone. ;-)

Niche,
I'd really look into switching the intake valves OR upgrading the valvesprings before you drop a valve. Better SAFE than sorry.

Bad *** car. I love these cars in white.

Your car, sir, is one of the reasons I decided to buy my '65 Impala! What an absolutely stunning car. I am so glad you are joining the LS club along with the rest of us, and I am happy to offer all the help I can with your build...so please don't be shy about asking!
what's the part number of the headers you use on your swap???
