My swap is complete 4bta 120 from van into a 71 chevy 4x4. I decided to do it on 7 Sep when I saw a 4bt for sale nearby. I bought the engine on 8 Sep. Pulled the 400 on 9 SEP. Since then I've worked 2-4 hours every evening after work and about 12 hours last weekend. I drove it to work this morning. Total time wrenching to include pulling the 400 about 25-32 hours. The only thing left to do is fine tune the TV cable. It is very important to get lots of parts from the bread van. exhaust, air intake, motor mounts, etc.. My motor mounts are ugly. I have 3/8 plate welded to the frame with 1/4 plate gussets at angles to reinforce. Hopefully they won't break. I used the bread truck rubber mounts. The nuts are metric on these! Try to thread on a standard nut and you will spin one of the studs making it useless. I will post pics by the weekend.
I spent all evening today trying to do sound insulation. I bought "fatigue mat" from lowes(1/2 high density foam mat for factory workers to stand on). I contact cement and screwed 1 layer under the hood, and 2 layers to the floor of the cab. I got 1/4 foil backed foam air duct insulation and layered the firewall in the engine compartment. I then used foil backed fiberglass insulation with spray glue up behind the dash. All this helps immensly, but it still is noisy. Now the noise is from vibration mostly. Maybe Hydraulic motor mounts would be better than the bread truck mounts???
