1970 390 Service Replacement Motor Standard bore 4.165 Rebuildable complete olong block with 291 heads Perfect motor for numbers matching car Service Replacement"" Multi-Displacement Block There was also a ""Service Replacement"" block made as a modified GEN-3 design. This is a 401 casting (same casting number) without the displacement cast into the side and with a 360 bore and thicker deck. In theory this single block could be built as any 343-401 GEN-2 or GEN-3 engine. A dealer could stock one or two blocks to use for warranty replacement. It was also sold as a heavy duty racing block, which is speculated to be the real reason it was produced in the first place. It appeared in 1970 in time for the 1971 Trans-Am racing season. Since it was a standard factory part it did not have to be homologated under T/A rules, and was not used in the 1501 ""Mark Donohue"" Javelins built to homolgate the ""duck tail"" spoiler. Those received standard 360 or 401 engines. $3000.00 or best offer Joe Booth boothx3@xxxxxxxxxxx 315 737 0066 ======================================== Anyone interested in the above give Joe a shout thanks Eddie Stakes' Planet Houston AMX 713.464.8825 eddiestakes@xxxxxxxxxxxxxxxxxxxx www.planethoustonamx.com _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.wps.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
