hey redoing the head on my truck with a 268 engnbldr cam and over sized valves, with getting the head shaved, and lce header but the short block is stock. Iv got 2 aisin carbs both need rebuilt but iv also got a 38 weber off my old 2wd 89 pickup and was wondering which would be the best for this set up, this truck im doing the work on is a 86 4x4.
