I've been researching different stroker configurations since i now have a spare M20 sitting on a stand. I'm reading conflicting reports.
What i know for sure:
What i'm getting conflicting reports on however is if an early M52 crank will require piston and block clearance work. According to this, it should work factory. I've read in places on r3v though that indicate that the cranks available in North America will always require clearance work.
I've never attempted an engine build before and i have no sense of how much work/cost it is to modify piston skirts and have the assemblies balanced. Does this have effects on durability? There is a decent machine shop where i work so making the spacer is not a big deal.
Finally, i'm interested in opinions on if it is worth the hassle over putting an ETA crank in. I want to build a street motor for my convertible. The intent is to drop the rear end ratio down to 3.25:1 or less. I find the stock setup to be a bit buzzy. The car is intended to be a GT car that is enjoyed most at 55-60MPH on back roads. Superior low end is the goal though i would obviously prefer not to loose anything up high over stock if possible.
What i know for sure:
- ETA crank clears without modification.
- Dual VANOS crank needs modification to clear.
