Description
Wiseco Professional Series forged piston sets for the Chevy L83, offered in 3 bore sizes: 3.780 in, 3.790 in and 3.800 in. Every option shares the 1.292 in (32.82 mm) compression height and -8.50 cc crown volume. Each set comes with rings and wrist pins.
What’s in the box
- 8 forged pistons
- 8 wrist pins (0.927 in / 23.55 mm diameter, 9310 steel, floating)
- Piston ring set
Matching it to your Chevy L83
Wiseco list this set for a 3.622 in stroke and 6.125 in connecting rods. Compression height plus rod length plus half the stroke comes to 9.228 in (234.39 mm): compare that with your block’s deck height to see where the piston sits at top dead centre.
Crown volume is quoted as -8.50 cc: Wiseco use a negative figure when the dish or valve reliefs add volume to the combustion chamber. Work out the compression ratio for your combination (chamber volume, gasket bore and thickness, deck clearance) before you order.
The bore size is the finished bore these pistons are made for, so have the block measured and then bored and honed to suit, with piston-to-wall clearance set to Wiseco’s figure for the option you choose.
Material: 2618 aluminium, the low-silicon alloy usually chosen for boosted and high-load engines (it needs more piston-to-wall clearance than 4032).
Forging: strutted design, with a coated skirt.
Ring grooves: 1.5 mm top, 1.5 mm second and 3.0 mm oil.
