Found this rebuilt 283ci locally for a great price. Still anchored to the rebuild crate from JASPER. It has side engine bosses for a typical SBC engine mount, so it will bolt right in my 1965 C10. I need to source some valve covers and accessories.
I purchased a rebuilt 307ci and turbo 350 as a package deal. The tranny will likely go in my son’s 1968 C10. The 307ci is a 1968 block with an Edlebrock performer manifold. It won’t make a lot of HP, but I got such a good deal that I couldn’t resist. Here are some pics. I don’t know what year block the 283ci is yet. Maybe the casting number will help. Also, I see 3 holes at the back. One is for a distributor. Holes A, B, C.
