[glow=red,2,300]Brand New WISECO Custom Forged Piston Set![/glow]
Band new in the box with oil rail supports and spiro lock no wrist pins. Although I have a set of Diamond racing wrist pins on the way for an extra $75.
Bore: 4.165" (.040" over 400 Small Block Chevy)
Compression height: 1.250" - works with:
6" rod with 3.48" (379.3ci) or 3.50" stroke (381.5 ci) OR
6.125 rod with 3.25" stroke (high RPM package 354!)
28cc dish (.196" deep, .436 deck thickness)
2.3"/1.75" valve pockets with 18 degree valve angle
Ring Type: 1/16" 1/16" 3/16"
[glow=red,2,300]Gas ported[/glow]
Groove lock spacers (W4956) required & included
Standard .927 wrist pin diameter (not included)
Spiro Lox included
Spec sheet & decals included
If you have a .040 over 400 block this is a deal of a lifetime piston set. These are custom ordered WISECO pistons made with a 28cc dish. According to my calculations (3.48" stroke, using Fel Pro's 1014 gasket .039" thick/4.2" bore, .015" piston to deck clearance) this gives:
8.46 compression with 64cc heads
8.18 compression with 68cc heads
7.69 compression with 76cc heads
8.91 compression with 58cc heads
1.250" Compression height ALSO works with:
5.85" rod with 3.8" stroke (414 cubic inches!)
This combo gives the following compression (same gasket, .015 deck, 3.8" stroke)
9.14 compression with 64cc heads
8.84 compression with 68cc heads
8.30 compression with 76cc heads
9.64 compression with 58cc heads
