Would still like to hear what everyone thinks about the new leakdown numbers using bolts now. Is the difference top to bottom thought to be acceptable,(from my post yesterday). Again thanks to all.
I would like to thank everyone for taking the time to answer my post, it is VERY good information. I now have more info and questions. First i would like to add that when i said that this motor was not broken in, it has not been started. As soon as i bolted the heads on i could not wait to do a...
Majik my machine shop provided me with the Total Seal rings, but i took it upon myself to call Total Seal for the proper finish and gave that info to the shop. Im using JE pistons with Lunati pro mod rods. This engine is being rebuilt, it was built 7 years ago was splayed and has a half fill in...
Forgot to say the reson for this question. I performed a leakdown test with the pistons at B.D.C. and again at T.D.C., all 8 cyl. at B.D.C. were 2%, at T.D.C. 3 cyl. were 15% other 5 were 6-9%. When talking to friends they have said the motors not broken in yet, i said its not broken in at...
What would the specs. be for out of round and taper of the cylinder bores of a small block Chevy. It is a regular production 400 engine out of a 1976 car. It has been bored .030 over and honed with a torque plate, and will be used for racing.
Yes, the rods are torqued to spec., and the mic.was checked against a standard. The crank then measured with mic. and the dial bore gauge zeroed out to that spec.(2.099), then the rod measured 90 degrees to parting line.
I built an engine once that had new rods and a turned crank, when the rod...
I was very happy with the wear on the hiperformance line of bearings that came out of my old engine and would like to stick with that type of bearing, they are a little tougher. The engine was together for 3 years and looked like the bearings were new.
I am working on a smallblock chevy and getting rod bearing clearances of .0045. I am looking for a clearance of .0025. I have a new crank that is measuring 2.099, in spec. but on small side, and new rods that are measuring 2.2252, in spec. but on the big side. I am using a micrometer and dial...
