1. I have 70 340 vert. Planning on swap to 440. I have heard plenty of flex on verts anyway and BB won't help. what is the word on subframe connectors? Will they be a noticeable help or waste of money. If needed, any suggestions on brand. 2. thanks to FEbo I also realized BB came with beefier torsion bars. Anyone make SB to BB swap and Not swap bars. How big of deal if I don't. 3. Sway bar... is there a BB front bar also and what about adding rear bar. How much if any will subframe connectors affect torsion and sway bar decisions? Lots to sort out as I swap, replace, and upgrade parts I haven't thought about or probably really understood in 30 years.
