|
| Here at Drews we use 3
axis digital readout and three step cut to bore every
block, a piston relief cut, cylinder clearance and
deck the surface where the cylinder sits for a leak
free perferct fit. This style leaves the maxium meat
in the block so it is less likely to crack, in fact
we have never seen a block machined by us crack in
the cylinder spigot! No need to weld behind #3 cylinder. 90.5,
92, 94 and 96.5mm bores available with any depth decking.
Custom machining always available! Bore
and deck complete block up tp 94mm $55.00. Call for
other quotes. |

|
| The heavy duty, precision
ROTTLER aline bore machine cuts the main bearing saddles
and thrust surface to a new size and alines them for
a "new" bearing surface for years of trouble
free use. No hand held tools here, just one machine,
one job, great results. We stock all sizes of bearings
to match your case and crank at the right price. Type
4 bore sizes no problem, center only or all.
Line bore and thrust cut block, $75.00, call for type 4 sizes. |

head studs a thing of the past........many sizes available with the 12mm O.D.
x 8mm I.D. the standard for use. Needed for boring to 94mm. Uses 8mm head stud
kit, just like the late style factory blocks. $45.00 for complete block plus
casesavers. |
Clearance Camshaft :

|
| Machining the cam is needed on large stroker engines, usually over 82mm, to
clear the rods and complete the clearancing process. Drews can cut the cam for
maximum strength and still clear the crank/rods. $28.00 per camshaft. |

that is needed to make your heads dual spring ready. Chevy style, K-motion and
exotic spring styles can be accommodated. Drews can help you match a good combination
for your needs. Cut pair of heads for dual vw springs, no disassembly
