I want to build a small block similar to the 70 Lt-1 I drove in high school. I really liked the sound, power, and high revs it would turn. I would like to use the original heads, intake, and similar cam. What compression do I need to be at to make everything work? I realize that 11:1 is probably too high, so what works with today's gas?
Would a ZZ4 short block work with my parts, or would the compression be too low?
Any ideas for a build would be greatly appreciated. I haven't messed with the car in years, but am eager to get it running again.
