I've finally gotten around to mounting a Chevy 305 with a Turbo 400 attached. I have a new engine cross-member and a new cross-member for the tranny. Some quick measurements seem to indicate a space problem between the stock cross member (the cross member at the back of the engine compartment where the rear of the old 6 cyl was attached - might be called the 'bell housing cross member). This member is rivoted onto the side rails of the frame on my truck. The turbo 400 will possibly just fit between this cross member and the firewall but will be close. I have seen on some of the truck sites that this cross member is cut out. I'm hoping someone will have some suggestions on this...I'm somewhat reluctent to cut it. The new crossmember I ordered (for the motor and tranny) bolt in - not welded and would not want to depend on them to secure the rails. Any recommendations would be apprediated.
