124in. Engine Build (page 1)



Here we have the blocks after being slipped into position with alignment tool installed in rear lifter block.



A close up of the alignment tool. Case flanges were wiped clean, again with acetone. Kevlar gaskets installed dry (they are marked front and rear...as well as the blocks themselves). Cam lobes were coated with assembly lube and the blocks and lifters installed. Kind of a quick balancing act to slip the blocks in, without the lifters sliding out. But the screws are installed with blue loctite...three per block, and I usually torque to about 6 ft lbs, the tool snugged in for alignment. Then tighten the tool up, torque the 3 screws to 10 ft lbs...remove tool and install the 4th screw...torque it to 12/13 ft lbs, and then final torque the other 3 to the same. Go to the other lifter block and repeat the same exact procedure, lifter fit in guide journal should not exceed .002 to .003.



Picture 43 has a few things to make note of. The blue circled notches in the cylinders spigots...are relief's for the piston cooling jets. The *NOTE and green arrows show that the wrist pin notches cut thru the rings path. Support rings are used once the wrist pins and  spring clips are installed to breech this gap, and the rings installed above the support rail. There is a dot pressed into the rail that should point down, and into the gap...to keep the rings end located away from the gap. This means that on this motor, the pistons wrist pin cant be pulled or installed with the piston still in the cylinder, as on many other designs. Ring end gap should also be turned away from intake and exhaust ports and staggered to reduce hot spots. Yellow circle shows cam side marking, purple circle shows S&S markings for front and rear, and P/N. follow the ring installation guide for rings, chamfer or dots up...and end gaps.



The rear cylinder slipped over the compressed rings, snap on makes the only compressor I have found that works...and not very well on these cylinders I might add. the rear is installed first usually if I remember to...it seems to cause less flywheel rotation, a major hassle with these cylinders. cylinder spigot holes are checked for burrs, and pistons should be checked for fit. again follow your specs as to cast or forged fitment. clean and dry again on the cylinders flange, and case deck. blue Kevlar's for this motor...although I have seen that vary as well.



The cylinder to head alignment dowels, tap or press them in lightly. no orings are used on this motor's alignment dowels/head gaskets.



Now all dowels are installed, surfaces wiped clean, oil is wiped onto the cylinder walls (don't want dry walls rusting, or a totally dry start-up), and head gaskets are slipped over the studs.



Your head bolts, all the same size on the SSW+. Motor oil is put on the threads/under the head of the bolt, and on the washers...to ensure a good torque reading. also the washers have a chamfer often, this NEEDS to go against the bolt head.

WOW! I'm about to contribute to CC again. The value of info like this... If everyone on here could pony up just $10.00 or so once a year... You'd all be getting a great value AND BigB would be able to afford all the redundant goodies so we would never go down...
