Weird Engine In A-Body

RBSGARAGE said
I Found A 340/727 In A 1967 Firebird Complete With Mopar Headers,only One Pipe On The Header Was Changed To Fit Firebird. Car Had Hawaian
Plates On It.turned Out To Be A Good Running Drivetrain For Only $300.00. Thats Been 20 Years Ago. Like To Find Another One For That Price

I'm pretty sure I saw something like this at M.I.R. one time. It ran pretty good.
I actually found a pic of it, heard it had a 340 in it.
