I cant believe that nobody has a answer.

How does lower radiator hose look like on astro with v8? How do you guys do it?

Can you post engine mounts details? Thanks.

I didn't buy the 400.

I got the gtr mounts already. I got them sandblasted. Today gonna pick up 400 .060 over for $250. Needs mild rebuild: hone the block and put new rings and bearings and it has new oversized pistons already . I guess I can run it carburated: swap 700r4 linkage from small quadrajet off 85 astro to big ...

Aftermarket, TBI/TPI or Vortec heads would probably cure that issue. Watch what you have vs what you get you may not like the compression that's a byproduct if you go this route.

Fuel pump does not turn on. Tried to hot wire fp relay without any progress.

Fuel filter replaced.

87 g20 tbi doesnt run unless starting fluid is being sprayed into it. New fuel pump and relay new spark module new distributor. Fuel pump doesnt prime and relay doesnt click. Oil pressure is good. Fuel pump fuse is okay. Where is the problem lays in?

Will a Chevy 4.2/4.8 i6 fit into astro if bolted to 700r4 and transmission stays in stock location? Or is too tall and too long? I know it does bolt in and I saw video of Tbi setup on 250 i6 on YouTube. Shouldnt be hard right?

Yep that's what it was. Thanks.

I looking at one 91 tbi safari. It cranks but has no spark. I thought its the coil replaced it but no difference. The coil itself doesn't get energized. Where to look?
