My first question is that on a carbed engine, lets say your just rolling along at about 40 MPH and then you suddenly floor the gas... is there a slight lag between the pedal hitting the floor and the engine putting out the power, or is the transistion seemless like a F.I. car? Secondly, in construction of the 1970 Buick GS Stage 1 motor, is it true that their was a material used in the construction of the engine that was also utlized by NASA at the time? *UPDATE ON QUESTION TWO* So I did a little googling, and I found out that hyoerreutectic pistons might have been used by Buick in the production of the stage one motors. Basically, Hyperreutectic is a combination of aluminum and silicon to create a more evenly dispersed uniform metal surface, and the pistons are brittle but awesome for naturally aspirated applications. Now what gets interesting is that apparently there is the regular 390 hypereutectic process, and then their is a NASA 398 Hypereutectic process. This was brought forth through the NASA technology transfer program, which basically puts aerospace applications into the industrial sector. What I'm trying to figure out is that what type of Pistons were equipped in the GS Stage 1 motor, and if the pistons were indeed Hypereutectic, then if they were 390 or NASA 398. Im not sure on the time dates for any of this though, but I was wondering in any Buick nuts out there knew this? Phew, this is alot of work.
