Yes. Similiar to the instructions above, but here are the parts that will be needed (including part numbers). The following are B&M parts: 700R4 Tranny 30-spline (117101), Hole Shot 2000RPM Lockup Converter (70417), TV Braket (90747), TV Cable (70242), and Converter Lockup Contol Dash Mounted (70244). Get a 700R4 tailhousing for the TH-400 bracket from Chevy (part# 8673406). You may also need a shortened driveshaft if you have a TH350. Finally, call Year-One for a TH-400 crossmember (part# 8606N for 67-69 models).
