FYI, the SRP 150727 pistons are 4.390 bore forged flat tops with a -3cc valve relief. It's spec'ed on the SRP site as a 501ci motor using 4.14 crank with a 6.8 rod and is 1.42 c/h. May want to check the part number again because the math won't add correctly for a 10.3 block with 4.3 stroke crank in any standard ford (6.605, 6.7, 6.8) rod configuration.

@Kjett believe me when I say this isn't my first engine build.
Never questioned your engine assembly skills. Just seems a bit low on the compression height than the FRPP 521 kit that Lem Evan's sells and will yield the same compression with a 28cc dish and a better compression height. Not sure you'd want to leave the piston .125 in the hole with a 10.3 deck height. Stock pistons were only .038ish in the hole with a 10.32ish deck height.

The original intent was to let others know what that piston p/n was originally for. ;)

Shouldn't the compression height be 1.54 on those 521 Ford kits? Add up all the numbers and comes to 10.30. Maybe I'm wrong:confused:
