Description
Wiseco Professional Series forged piston sets for the Chevy Small Block, offered in 4 bore sizes: 4.030 in, 4.035 in, 4.040 in and 4.060 in. Every option shares the 1.550 in (39.37 mm) compression height and +13.50 cc crown volume. Wrist pins are included; rings are not.
What’s in the box
- 8 forged pistons
- 8 wrist pins (0.927 in / 23.55 mm diameter, 5115 steel, floating)
Rings are not part of this set, so order a ring set to suit the finished bore and the ring groove widths listed below: Wiseco piston ring sets.
Matching it to your Chevy Small Block
Wiseco list this set for a 3.480 in stroke and 5.700 in connecting rods. Compression height plus rod length plus half the stroke comes to 8.990 in (228.35 mm): compare that with your block’s deck height to see where the piston sits at top dead centre.
Crown volume is quoted as +13.50 cc: a positive figure means a dome that takes volume out of 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.
