hey guys i am finishing up my engine build and im down to choosing bearing sizes. i just had my block align honed and the crank balanced and polished. while i was getting the h23 sleeved the block cracked so the mechanist used a h22a4 block, so im alittle confused on which bearings to choose. the mains were honed to 59.02mm and the mains on the crank, crank pulley side to flywheel
1) 50.01mm
2)50.01mm
3) 50.02mm
4)50.00mm
5)50.00mm.
the rods are crower with 51.00mm big end with crank again same order
1) 48.00mm
2) 48.01mm
3) 47.99mm
4)48.00mm.
if anyone could help me out that would be greatly appreciated. if i need different info i will get it.

thanks for reading

 

you can't put an h23 crank in an a4 block.

 

as long as its a 97 year a4 block it will work.. but i am confused..59mm mains?

 

there is a 9 millimetter difference there. and their arent any 4.499mm bearings to my knowledge.

 

yea taht started to look confusing for a second...
