4.6 HC motor - comprssion

Post by walker »

Does anyone know what compression to expect out of a 4.6 HC motor?

A friend just bought one 2nd hand. He is getting 150psi but does not know if this is normal.
Thanks,

Adam

He bought it second hand.

The motor was advertised at $3k but he ended up buying the entire Rangie for the same price.


I bought a 4.6 short motor about 2 years ago for $2k. I am just about to start a rebuild on it and will be installing some new HC pistons I bought. I got the pistons and rings for $800
Thanks,

I will do most of it but will get the pistons installed by a specialist.
Thanks,
