"Stock" cam NHRA says is .465 in & .473 ex any duration, I think.
The 69 intake is the cast iron version that the LD340 was copied from.
Any 1.5 rocker is now allowed.
An the piston rod rings and wrist pin are weighed as an assemble now instead of individually.
And I believe the heads are 2.02 and 1.6 valve with a 64cc combustion chamber.
