3 full tanks of fuel in and around Charlotte once I got post start gremlins sorted out. 19.9mpg, 20.1mpg and today's tank - 20.7mpg. Not too shabby. Time for a longer road trip to see what happens on cruise out on the interstate.
Thx! Kind of funny - perfect weather this morning for a local Cars&Cappuccino gathering - 95% Euro stuff (put on by the local Porsche Club). While I was the ONLY one taking the picture below, there were about a dozen folks gathered around the front end of the beige Volvo parked right across from the Testarossa....but oh the sound when he fired it up.
Edit - and thanks to our friends at photobucket, that pic of the Testarossa engine went missing....

I was curuious what the MPG would be on the LS3. Mine will probably be less, as my '61 is heavier.
I get 22-23 on the road with my LS1 in my '56 convertible.
I consistently got 25-27 highway with the modded 5.0L in the car. I figure the LS3 will be similar under similar conditions. More displacement -- but more efficient with higher CR and a more contemporary ECU.
Have you had the vert on scales Roger? How much? Weight is a bigger mileage penalty around town than on the highway.....aero is the key there. Although neither of our "bricks" are going to win an aero contest.

That's for sure!
It's been a long time since I had a weight on it. I may not even be remembering for sure...seems it's around 3400lbs, but that was with the 350 rather than the LS engine. ... I just looked up specs, and 'shipping weight' is 3340.
Edit- traded this 2015 Fit to my daughter, and 3 months later around Thanksgiving she got t-boned = totaled. RIP little Fit! Air bag hit her hand pretty hard, but nothing broken.
Hijack my own thread -
Today, in the DD Fit, I made the NASCAR drafting instructors blush. The end of bike week in Daytona provided this Super Sugar Daddy for my last 40 or miles into Charlotte. Based on diesel exhaust of the tractor -- mega HP -- he set his cruise on 68 mph and never varied up hill or down. PERFECT. And perfect weather conditions. I was never any closer 6-7 car lengths behind him. Ethanol free tank of fuel.

A dream build, right here (though I'd have to go for a wagon).
You did a lot of fabbing to get that motor in there (it looks nearly factory—well done), but are there kits you could have purchased to make it easier? I only know of motor mounts.
I don't have the resources to weld or make parts, but I would love to have a 245 that was by all accounts stock except for the 300 extra horses (heat, AC, quiet exhaust, low vibration, etc). The ideal cruise missile under the radar for road trips.
STS (Oregon) makes a motor/tranny mount combo - but it's for an automatic, and it's designed around an engine height and exhaust manifold combo that I wasn't particularly fond of. So I just did my own. I found pretty quickly - the challenge with kits is you live with someone else's choices of engine/tranny height/angle, oil pan and exhaust manifold. I wanted the engine as low and as far back as I could get it -- and was able to accomplish that by doing it myself.
With all the extra torque, wanted a bit less rear roll stiffness, or at least relative to front. Replaced front 25mm bar with a 28mm bar. Replaced rear 25mm bar with a 22mm bar. Had to do some cutting/welding on the exhaust system to clear the new bar which was bent a bit differently than the old 25. But all clears -- exhaust now more symmetrical and clear/quiet than it's ever been. Happy boy.

Gorgeous morning here in Charlotte, low humidity, low 60's. So early this morning I took the car out for an 80 mile jaunt round the 'loop' here in Charlotte. Virtually no traffic and speeds varied between 60-70mph on the cruise most of the time. I filled up afterwards -- 140.1 miles on 5.95 gallons = 23.55 mpg. But here's the kicker - I had 56 around town miles on the car before I started out. My last 4 tanks around town have all been in the 18.5-20.1 mpg range. If you do the math and assume that those 56 miles were at 19 or 20 mpg -- then my 84.1 mile lap today netted 28.0 or 26.7 mpg. Not too shabby for a 430+HP V8 in something that ain't too aero. Looking forward to a trip down to Augusta to visit family and take in a Cars&Coffee - then I can do a real highway mileage check.
