HUG 426-RACE-KFH STROKER KIT, 360/426 SMALL BLOCK SMALL BLOCK 426 CUBIC INCH 'HEMISIZED' $2595.00
 Small Block 426 Cubic Inch "hemisized"
This is a premium kit including forged pistons, "H" beam billet rods, and a forged crankshaft. Naturally, all of the correct rings, main & rod bearings are included (as you would expect from us). This kit is internally precision race balanced.
We designed this kit for hot street/bracket racing where maximum torque is needed and a light bob weight for quick acceleration is desired. It can be installed in either the 360 "LA" block or the newer Magnum blocks that can clean up at a 4.030" bore.
The forged pistons are a step dish design giving a compression ratio of 10.39:1 with a 58cc chambered head and 9.74:1 with 65cc chambers. Our goal in designing this was a good premium pump gas ratio with either iron or aluminum heads. The forged crankshaft will have a standard 360 main bearing with NASCAR sized rod journals (1.988"). The stroke is 4.180". The lightweight rods will use lighter weight 0.912" pin diameter and will naturally be full floating. Minimal notching will be required to allow this kit to drop in. We strongly suggest that you use our main bearing support girdle with this long armed screamer. These kits will be internally, race balanced.
We are balancing and shipping these now!
