coated pistons? Right now I'm putting together a new motor for my truck, currently the block is in the machine shop but I'm still in the "parts gathering" stage and I'm considering my options..
Current plans for the motor stand at:
350 roller block (from '88 Chev K1500 - in machine shop right now, getting new cam bearings, frost plugs, checked for cracks/defects and having glaze broken)
400 Crank
Eagle Rods
Roller cam/lifters (Cam selection undecided at this point)
Vortec Heads
Crane roller rockers
LT4 Intake (modified for dizzy/Vortecs...check thirdgen.org forums, its been done)
zero-decked block
TPI SD ECM (P4)
TPI harness (modded if necessary)
All this going in a '72 Cheyenne/20 that currently has a TH350 and 4.11 gears out back (tho depending on circumstance I may be putting it in a first-gen blazer I've been looking at). I want to have a very, very, very torquey motor at low RPM's that can also put out some descent power up top (thus the vortec/LT4 intake combo). Ideally I want to be able to dust mustangs in my heavy ole pickup but more realistically I want this truck to have a LOT more power than stock and have no problem accelerating while pulling my 24' trailer, get as good of mileage as possible and last a long time (If I can't dust mustangs without nitrous, I guess I can't dust mustangs...)
Right now I'm up in the air about pistons. I'm fairly sure I'll be settling on *something* hypereutic, but I've heard good things about coated pistons for engine longevity, minimal energy lost as heat, cooler running and better mileage.
I'm curious if anyone here has had direct experience with coated pistons, and whether or not you noticed any difference versus stock or forged/hypereutic aftermarket pistons. The ones I've been looking at are here:
Ebay item 7982599919
$149 for set 8 pistons, wrist pins, pin locks + 14.00 shipping.

I'd most defiently go with a forged piston, I'd spend the extra money and do it right the first time. I'd either suggest going with a ross or wiesco piston, we have had very good luck with them.
Where in MN are you having your machine work done?
