The LSX Swap Build Thread




Have a 1985 Iroc-Z that I am the original owner. Drove for several years and then collected dust in my garage. Have decided to do a complete tear down and rebuild with a modern drivetrain. Plan is 440CI LSX, 4L60e trans, Moser built 12-bolt, all UMI tubular suspension, sway bars, poly bushings, etc. Complete rewire of car and switching to Holley Dominator EMS. 6-point cage, full paint and body work, and custom leather interior. Wilwood brakes all around along with rebuild of all systems in car not mentioned. Some pics of teardown. I will post more as progress continues.

Engine Setup similar to what I’ll be using except will have a Air Force intake. Built by Late Model Engines in Houston.

Looks awesome. What heads will you be running? Will this be an N/A motor?

Nothing mid level about that. That power curve will be fat.

Re: The LSX Swap Build Thread



​​​​​​Sold the car to a neighbor about 11 years ago and he spent a little money on it. Tune, new carpet, stereo. Drove about a year then got caught in an affair and wife took him to cleaners. So, bought car back from him. Point of story is he had the entire inside floorboards and rear area “insulated “ with foil backed butyl based roof seam insulation. Kind of crap you get at Lowe’s/Home Depot. Have spent the last week with a vibrating scraper and then wiping residual tar with lacquer thinner. PITA. I know some folks advocate this as poor mans Dynomat. Dont. Just don’t!
