Thanks Xnke, I'm hoping #6 falls back down (student budget doesn't like premium!) but good to hear this isn't cause for too much concern.

Went to go see an early 71 240z today, did a compression test and got 1 179 2 168 3 163 4 170 5 167 Exhaust(?) valve was stuck open for the first couple tries (0 pressure). Took off the valve cover and popped the spring back on right and got the 167 reading 6 200 why so high?? The engine is a L28 N42 block and early E88 head with SU carbs, been sitting for 2 years and I had to test it cold because the car doesn't run (no fuel) ps. How do I fix the valve stickiness?

Hi all, I'm new to Zs, looking to buy one soon, with a non stock engine combo: L28 N42 block E88 head with early carburetors on it I did a search and haven't found any people with specifically this combination. How will the compression ratio on this combination be? the car is an early 71 Z with the swapped l28 block.(I'm assuming with the early 71 head?) I know this is probably not enough information to make a judgment about compression ratio, but I'm just a bit worried that I haven't found this combination on the boards. Also, I'm new to carburetors. I'm going to need to replace the fuel lines, tank and pump for this car. Do carburetors require an FPR? Should I switch to an electric fuel pump instead of replacing with a stock pump? what is involved with the switch? Thanks for reading.
