I am doing a 4.6 rebuild and am looking for a set of 4.0 high compression pistons. The 4.6 ones are shot and I might as well make the most of it. Let me know and thanks for your time.
Yes.Don’t regular 4.0 pistons give high compression when paired with a 4.6 crankshaft and rods?
Geez, what does 9.3 become when you pair it with a 4.6 crank and rods? will this require octane booster?Yes. You are right but I thought that there were low compression pistons for 4.0 as well. Maybe I am wrong. I thought one was like 8.5 and the other was 9.3 roughly.
Nice bump but not crazy. Please post back your assessment of the improvement when you get it going.I thinks it’s right around 10
