What can a 430 cu in block be bored to safely without any worries about wall thinning? The motor is from my 67 RIVIERA GS car that I pulled out of a field about a year ago and am starting to do some work on it to get it moving. The car supposedly sat in the field for about 20 years so it needs everything. I just pulled the motor and trans this past weekend. I took the heads off of the motor to see the bores and they all look pretty good.
I also was recently given a 455 out of a 73 RIV from my brother, but when I pulled those heads one of the pistons was cracked (#3), but all of the bores look good. Surprisingly there is no scaring in that cylinder even though the piece of the piston top and a portion of the top compression ring are no where to be found, even the valves look good. This motor was never opened since it was pulled from the car was being scrapped due to body corrosion, it was still running about 15 years ago at the time, obviously that cylinder had a problem though.
just asking, because I am not sure which block to send to the machine shop to start with. I know to keep the car original it would need the original motor and trans, but at this point I am not sure that that really matters due to the condition of the rest of the car. Although I have high hopes of making it nice, it is my retirement project.
Any thoughts/info would be appreciated.
