'73SResto: 2.2E Pistons swap
So, we are putting the engine back together and turns out the original pistons are a bit too pitted to go back in. The project didn't budget for new pistons. So, we have located a set of 2.2L 'E' pistons that fit the budget. I know that this will raise the compression up to a ratio that is close to having to worry about detonation. As previously posted, I've already machined the heads to fit twin plugs, but haven't the $$ to put the twin ignition in yet (maybe next year).
I read in Bruce Andersen's book, that putting 2.2L S pistons into a 2.4L S engine only raises the compression from 8.5:1 up to 9.66, which he says is still w/in safe single-plug limits. Does anyone know what the E pistons do to the compression? Remember, this is NOT a race car. I did modify the cams slightly (nothing radical). Also, I live in CA where we can only get 91 Octane gas.
Will this set up be safe (as far as detonation goes), and will the result be streetable and livable? Also, what are the options on pistons that are pitted? Can they be machined or is there too much clearance as a result?
Thanks
