I’m about to swap a 350 SBC and a 700R4 into our 70 Blazer. I’m using the advance adapters output shaft so I can reuse the Th350’s NP 203 adapter.

Can I measure the TH350 length vs the 700r4, and just slide the engine crossmember forward, so I can re-use the rear driveshaft?

If all goes well, we’ll be driving it from Dallas to Long Beach the weekend of Sep 14.

Thanks in advance

Wes
