It's been a while since I've actually had to rebuild an engine and I measured everything up and wanted some second opinions on my clearances and some advice.
I'm doing my engine and one for a friend right now.
Mine is a 6-bolt. I'm using King Racing bearings with the extra clearances on both.
Mains are .0025-.0035" and the rods are .0030-.0040" is that too loose? I also have both sets of the standard bearings as well if i were to need to change them. Car will be making in the 700whp range and is typically summer/track use only.
Second engine is from an Evo 8 It actually spun both the 2 and 3 Mains, but after taking it apart the damage looks very minimal surprisingly. Car ran, just had 3-5psi of oil pressure. All bearings were fairly worn. Looks like it was incorrectly assembled. (had the upper and lower mains all mixed up) It only had about 3-5k miles on a full manley 2.3 rotating assembly.
I'm going to start by measuring all the main bores. Anyone know the spec?
Also any advice? Car has a FF FP3794 ect. So it will have to take some abuse as well.
