JTR V8 Swap Conversion Kits
JTR (stands for jaguars that run) started off fitting Chevy V8 engines into Jaguars and publishing a manual on how to do the swap. They also went on to offer swap manuals for the Datsun Z, the Volvo 200 and 700 Series, and the Chevrolet S-10. Their manuals take you step by step through the process of swapping this american muscle. If that wasn’t enough they offer the parts as well.
