Clearing Up Mod Motor Misconceptions With John Mihovetz (https://www.enginelabs.com/features/clearing-up-mod-motor-misconceptions-with-john-mihovetz/)

I stumbled across this article today. Now I know why so many members recommend the Teksid 4.6L block.

Lots of interesting points in the article:
- iron vs aluminum blocks
- how great DOHC Cobra heads are
- benefits of longer cylinder liners with custom sleeves
- polishing of the outer chain of the Cobra timing chains; this decreases the amount of wear that the plastic timing guide will see during operation.

The Downfall Of Stroker Rotating Assemblies
“The real issue is that a longer cylinder liner needs to be installed to accommodate the stroker components, and most guys that are buying these kinds of kits don’t have the means to install a set of custom sleeves that cost more than the rotating assemblies themselves.”

Just read it. Interesting to hear that the factory stuff is more than up to the task of supporting plenty of horsepower. Good read for sure

I went to a local salvage yard and found multiple RWD Lincolns with the TEKSID engines.
Pulled one out and stripped everything off the short block.
Then they were trying to charge me for the pistons, rods, ....:blah:
I said; "Fine!"....:mad:
lugged the short block back to the Lincoln, took out the crank, rods and pistons and left them all lined up on the hood of the MK 8.
Never did use that TEKSID block...sold it to a member for his build.

I'd like to know how the new Coyote block stacks up against the TEKSID.
The new Coyote blocks are supposed to be plenty stout.

I think our MM heads are the "C" heads. Does anyone use the "B" heads in their MM, for the reasons described in the article? I had a set & just junked them.

My uneducated opinion would lead me to believe that our factory heads with mild work would perform extremely well for "street bruiser" power levels. I think these guys in the article are really on the razors edge with 3000 HP builds spinning at 10k+ RPMs so they have really found every last drop if you will.

The 3v aluminum block is the last iteration of the 4.6l NVH and is the strongest. That’s the same block the aluminator was built on. Our C heads flow great and only need port work with high boost levels. Here’s a pic of the Nemak 3v block identification:
