tonight it grew P &C's...Make sure to clean your parts before you weigh them, the difference was not small a gram or two...After the pistons were clean the opposite ones weighed exactly the same. 1&3 454.2 grams and 2&4 454.7 grams, the pins only varied by 1.3 grams from 110.8g to 111.1g so I just swapped 2 pins, to lessen the the diff from the heaviest set to the lightest. 1.3g is good enough for this mostly stock engine that wont see over 4500 RPM.
The Mahle pistons waiting to be put into it's cyl.
I painted the studs gloss black.
You can see the marks I found all ready in the pistons from the prev builder, and the remainder of the factory paint marking. (The yellow and blue paint) The yellow was a complete circle around the blue dot before I cleaned them.
I used a regular cheap sheet metal ring compressor and put the pistons part way into the cylinders and then put the pins in. It's probably easier to just get a VW specific ring compressor that'll let you compress the rings after the pins are in. No big deal I needed to get this engine together, to make room on the table for Hemi parts. Upgrading the cam in my 528 Hemi to larger solid roller one, from a flat tappet, the new one is also much more EFI friendly, with a large LSA. Should be good for about 100 more HP too, to 700! This is in a 68 Charger.
Anyway next to fab something to hold the clys down so I can check deck heights and equalize if necc. And get on with grinding on the heads. They are no where near ready, I've just taken them apart (removed the valves) and cleaned 'em.
