Story:

The Chevelle was bought by my family when I was 2 or 3 years old.  The car was originally a 283 3 speed manual car. It was not until the current teardown and LS swap build that we found out it was originally a 3 speed manual 283 car as it was a 350 powerglide setup during purchase. While growing up we would use the car to take to cruises, the drag strip and road trips to visit family.  We were not afraid to drive it in inclment weather. The chevelle had housed a couple different small block chevys before the LS swap began.  I started driving a GMC Typhoon in high school, so the Chevelle was put on the back burner while I cut my teeth on Turbo EFI stuff on the Typhoon.  In that time, the 355 was swapped out into another car and left the chevelle sitting for about 6 years.  When I graduated with a Mechanical Engineering degree, we quickly took action on the plans to perform a LS Turbo install.  My prior experience with Turbos helped convince the family this was the way to go for “reliability” and power. LS engines were gaining in popularity, and wrecked trucks were looking appealing for their drivetrain.

I leaned on a friend Jeff Jost to help with all the LS swap questions and also spent lots of time on LS1tech.com looking for inspiration and cheap 2nd hand parts.  We sourced 90% of all the speed parts used from that site.  I bought my first welder and learned how to rework a efi wiring harness during this process.  We tried to do most all the work in-house to be able to learn more but did have to source out help with tuning and transmission work.  It took about 2 years and importantly 2 long winters to complete the car from a rolling chassis to running and driving.  The car just put down a good 600whp on the first tuning sessions.  I was introduced to Autocross and some HPDE days the first year of getting the Chevelle up and running.  Needless to say I was hooked.  We have spent the last 4-5 years upgrading the chassis and suspension to handle the big power as well as make the car turn left and right.  UMI Performance and Viking Performance are key pieces to this puzzle on putting the power down and making this big car turn.  The engine was upgraded from the stock junkyard motor over the years to a more reliable setup as configured today.  Power have slowly worked its way up from 600WHp in the beginning to 921 WHp now on E85.  It has a 1000whp capable setup, but we have not leaned on the tune yet.

Acknoledgements:

I would like to thank the following people for the help along the way.  The family and friendships made are unvaluable. George and Miriam Nall (mom and dad),  Sheryl Nall(wife), and Hudson(future chevelle owner), for keeping the car in the family and continuing to make memories with it.  They all put up with long weekends at shows and events locally and across country.

Chris and Christie King from Viking Peformance, Ryan Kirkwood from UMI Performance for all their help to make this thing handle.

Also thanks to all the work and support from friends for keeping the car running and constantly improving.
