Engine Building Question
This board is loaded and I mean just loaded with guys who are a vast pool of knowledge on building an engine "RIGHT". So with that thought I have a question, elementary granted, but a question that needs an answer none the less.
What with the economy like it is, there are so many good cars out there for sale that it isn't even funny. A deal came along for me I simple could not pass up. I am and have been for many years a real fan of 55 Chevy post cars. When this latest one was offered to me I simple could not pass it up. Very nice looking car-- The color is not to my taste but you can't have everything-- it has a brand new interior and is in fantastic shape. Almost an orginal car, it has had a small block engine change a few years ago and a turbo 350. The engine it has now is a pretty anemic 305, absolutly stock I believe with the exception of Headers and intake manifold and a Edelbrock carb.
I have no use for the 305 and I do have a 010 casting 4 bolt 350 setting in the shop I got "with" another project a few years ago. I also have a set of 186 casting Double hump heads with a fresh port and polish, these are 2.02/1.60 heads, screw in studs push rod guide plates etc. these heads are very fresh and ready to go.
I opened up the 350 today ( never had looked inside this motor before) and it does have a fresh low milage build on it. It is .030 over with some brand probably TRW flat top 'cast" pistons, fresh rod and main bearings and the crank looks fresh as well it is a .010/.010 crank. I checked the end gap on the rings and it will need new rings. I also checked the cylinder taper and it is very minimal less than a .001.
This brings me to the question. I would like to replace those TRW pistons with something a little better. I have always rebuilt an engine from the bottom up, took the block in to be bored and took the pistons in for the final fit and hone. This time I have what appears to be a pretty fresh block that is now .030 over can I buy a set of .030 pistons and use them as they come? This is what I would like to do, any problems with this somewhat of a shortcut??
RolandProtected people will never know or understand the intensity life can be lived at. To do that you must complettly and totally understand the meaning of the word "DUCK"
