8.1 Chevy Vortec Swap....

[69MyWay]

And....it is done. We wrapped up with a dyno tune session last week at www.1320hp.com in Lenox, IL. Mike Hornback tweaked the PCM to an all around smooth tune.

For a cam with less lift than the one stuffed in my LS1 69 Camaro - this is impressive. On a cold day, the car is making nearly 600 ft lbs at the crank.

When I took the car for a test drive, I was shocked at how it would just blister the tires in 1-2-3 gear from a roll with NO effort all...and now I know why.

So...what's next you ask? I am going to wrap up the plumbing on the a/c system and install the gauges. I'll also go ahead and wire the entire chassis...then she all comes apart to roll the body over and get it prepped and ready for paint. We already have all the interior..etc, so when it is painted I just have to assemble. We may be putting 2010 ZO6 calipers on as well as a few other fun things before I pick out the rolling stock.

I'm a happy camper. This car is going to be a blast with enough power to slam you in the seat at a mere whisper on the pedal...but smooth enough to idle like a Caddi and just sip the fuel in O/D (plus cruise control).

Congrats, I bet it's a blast. One thing though, as an owner of an 8.1 powered Suburban....the sipping fuel part. lol I'm not sure if I'd say that they sip fuel, but I'd be real curious as to what kind of mileage you can get out of one of these 8100's in a small, light car with enough OD to keep the RPM's really low, like 1500-1700. I would think that it should be above 20 mpg, but the key is keeping that rpm down. I find that my Suburban does best when I drive 50-55...which the best it's gotten was 14.5 mpg (but that's with 4.10's and a 4L80). What rear gears are you running again?

Running a Richmond six speed tied to a 3:55 rear gear on what should be 26 or so inch tall tires. The 69 Vette has a low drag coefficient, so I suspect it will be smooth.

I was able to get right at 20 out of my old 69 Vette with 3:55 and EFI 468 Rat.

Look for the magazine article series (June and July 2010) in Corvette Enthusiast. I was able to expand on the whole process there.
