Re: what would I need to go from a small block to a big block
What kind of realistic power will the big block be producing? What will need changed will also depend on just what you have with your small block. For starters, you will likely need to change the radiator and shroud. Unless the TH350 is built for the increased torque, you might be best off to upgrade to a TH400.

Re: what would I need to go from a small block to a big block
In my 82 I needed:
Radiator/fan/shroud Engine accessory brackets for BBC Engine Throttle cable TH400 or TH475B with 4" tail shaft New transmission cooler lines After market TH400 kickdown switch Custom Driveshaft with TH 400 yoke to 12 bolt saddle Once you have all that and a tiny bit of wiring you'll be good to go. |

Re: what would I need to go from a small block to a big block
I'm doing a SB to BB swap right now. Why was the throttle cable swap needed? Thanks in advance

Re: what would I need to go from a small block to a big block
First is if you set them side by side the big block cable is about 1" longer. You may not need to on your truck but my big block had a performer style intake. Of course there's also the 30 + yr old factor and nothing ruins your day like either a stuck cable at WOT or no connection at all because it broke.
