Keep the Olds,there is plenty of aftermarket like Mondello
http://www.mondellotwister.com/ ,
with the right pile of mostly factory parts the Olds is a winner,cheaper to build,easier to work on,NO COMPUTER/WIREING,less fab,and even though its the factory engine,you would be hard pressed to see another that hasnt been swapped nowadays,they are TORQUE MONSTERS, crap HP- but for a street car the torque from the Olds will propell you in front, light to light that is, they have a ugly power and tq curve-but for the street its golden. JUST MY 2
BTW verry sweet ride,paint looks nice on that, dose need a different size tire on back to fill the wheelwell or slam it on the ground

and drive slowww, cant show that clean nice classic going 100 ,going fast is overated,unsafe and verry costly for a street car,cant wait to see progress.
