|
| 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. |

Your case can be "casesaved" by Drews to make the problem of stripped
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.

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. |

Dual valve springs are needed for aggressive cams and hi ratio rocker arms or
when maximum horsepower and RPM is wanted. A simple machine operation is all
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 or reassembly, $25.00.
