Bought mine in 1981 for $850.00 and still have it. Was originally Bronze with a white top, white bumblebee stripe and a white bench seat interior. I couldn't stand the bronze (like it now though) so in 1985 I stripped it to bare metal (no rust) and had it painted FY1 Top Banana. At this time I added headers, a Crane Econo-Power cam with Rhodes variable duration lifters, Chrysler electronic ignition, Torker 340 manifold and 3.91 gears. I also omitted a few things because they didn't pertain to going fast, things like insulation and power steering (I want it back now) With this combo I ran 13.50.
In 1988 I rebuilt the engine with 8.5:1 pistons, replaced the Chrysler ignition with a MSD and added the B&M forced induction. I changed the gear ratio to 4.30 which netted me 12.50 quarter mile times.
The second time around in 2000 I had it repainted again (thought about black but fell victim to the FY1 curse).
2010 added the Comp roller cam and lifters and had the X heads redone with hardened seats (already had stainless valves I also had a multi-angle valve job and port work done. I was able to run 11:50 with this setup. These cars are ever evolving and are never truely done.
