I bought a Mirada over the summer with a cast crank '73 340 in it. It had 567 heads, TRW 4-vlave relief stock replacement pistons, cast crank, etc. Nothing spectacular.
I wanted to raise the compression, better heads, etc. Then I got to thinking that if I'm going to buy new pistons, rods, heads, whatever, would it be better to sell the 340 to someone that wants to restore something and find a 360?
The intent for the car is to race it for a while until I put together an overdrive conversion for it, then make it a fun street/strip car. With parts being the same, what would you think? After reading through the 360 stock crank thread, how does a 340 cast crank compare? The 340 is .030, I don't know anything about if it was sonic tested or not.
Any advice? Would you run a 340 over a 360 in a Mirada? (Clearly, originality isn't a huge concern).
