Why would you suggest this?
The original post said FI. I always though FI is usually short for Forced Induction, ie supercharging or turbo and EFI is Electronic Fuel Injection. I thought his post made perfect sense.
If you are not going to build a hot motor, just get stock replacement pistons, like the FRP slugs from Probe. Buy the pistons, take them to the machine shop with you, along with the recommended clearance (from probe; piston-to-cylinder-wall clearance) and the shop will get the bore/hone right. This is not absolutely necessary, but I do it for performance motors. You can take the rotating assembly at the same time for balancing (pistons, rings, pins, rods, rod and main bearings, crank, damper, and flywheel/flexplate).
Before you do anything I would make sure that the block does even need to be overbored as Cochino mentioned. If your block has the standard bore still with less than .011 in. of taper from top to bottom than it can just be honed and still use the standard size piston. I tyhink people are way to eager to overbore their engine and they always seem to jump right to a .030 size. The first step can be a .020 size though which leaves you plenty of room for doing it again down the road all the way up to a .040 one day. I know alot of folks do it but i would never go .060 on a small block.
I think stock '87 HO pistons have valve reliefs and are forged. Guess you'll find out what's in there when you tear it down.
BTW, my suggestion of stock-type pistons doesn't fly if you use an intake valve larger than 1.90 in the heads. Just in case you were thinking of using performance heads ....
D.Hearne, I'm like you ... FI meant fuel injection. I remember talking about FI Chevy heads, which were the hot ticket back in the day for my 327.
Ford didn't need mech FI for the small block 'cause they offered the Weber conversion over the counter at the parts dept. That is very close to fuel injection and they make wicked power over most carb'd setups. Mine aren't even tuned, yet, and I'm still amazed at the power gain, all over, that I have now compared to the ported Stealth/650 HP DP setup I had. I go for tuning/dyno pulls Friday and will post results.

When ordering pistons for it, watch the pin heights. You want a 1.610 pin height to keep the piston as close to the deck as possible. This means more compression for N/A applications, if you do decide to go F/I, then you can always tailor the boost to match or get a dished piston if you don't want to do that. The reason I suggest watching the pin height is not all 289/302 flat tops have the correct height for a near zero deck. There are many on the market with a 1.585 P/H.
