Hi guys,
I'm new here, located in Melbourne Australia and building a '71 Challenger from the ground up...
It was an original 318 car (a Deputy Challenger which turns out to be kind of rare, who knows).
Anyway the motor has been rebuilt (never run) but with low comp pistons that I calculate at about 7.9 to 1.
There is about 3mm measured from the deck that the pistons are sitting down the barrels.
It's be bored to .030" over so my question is: I want to run higher comp pistons that have a longer length from the pin to the flat top.
If there are any engine/machine guys reading this will there be any way I can order .030" pistons (such as what Keith Black offers) but not have to rebore the engine entire deal again, hone only perhaps?
Also, the pistons in it (that sit way low down) have the 4 valve type cutaways... What other piston options will I have that will get them higher without having to shave a stack off the deck – 3mm is a long way down obviously. It's going to be a daily driver so I'm looking for pistons that are not super expensive...
Thanks in advance for any thoughts,
Nick McGee.
