Engine/Tranny Differences 8.5 to 99/00

I've asked this a few places with no real answer as to whether or not it's true. According to http://everything.explained.today/Ford_Contour/ The engine has had abrasive flow machining which adds 5 horsepower and the tranny has had revised syncros to address an issue in the 98s. The site lists early and late 98s separately as you can see. I'm just wondering if this is accurate information and mainly if there is any significant difference in reliability and longevity to engine and tranny due to this if it is true. Thanks.

Only the V6 SVT 2.5 had the intake manifold internal polished by the abrasive slurry method to smooth the flow. The info on the syncros is VERY wrong. Early Ford MTX75's had a 'twin blocker' on 3rd gear, later MTX75's went to a single blocker. A single blocker is LESS efficient than a twin. This was a mechanical 'downgrade' NOT an up grade. For Ford it was just a cost save as the single blocker used was the same as 4th & 5th gears. And cost less than the 'unique' twin used on 3rd.

Oh well that's good to know! Thanks Terry! The 98.5's have the twin blocker then? And the abrasive slurry method polishing was done post this model correct?
