I was reading a GM power book in class today. It had a section devoted to 60 degree V6's and performance, I'm sure some of you may have seen the same book. Among some highlights of the read were. A picture of headers that crossed over the current location. They were extremely professional in appearance and if I had to guess, they were the ones made for the Beretta pace car since they were done by GM. They also had specs for the current block vs. the Aluminum Bowtie Block.
Of other note were statements that on a performance rebuild it would be possible to swap in Double Spring Valves from a Small block v8 and also use v8 Connecting Rods. Of the rods, they stated that the length would be no problem, however the wrist pin diameter would be too large on the v8 rod and it would have to be rebushed.
Just wondering if anyone else had read the same. Some of the ideas would really help beef up the bottom end of the 3.4 but of course in the end the death would be the 4t60.
Just for my info, last time I saw the topic mentioned, a 4t65 swap was impossible. Yesterday I was browsing some boards that talked about a 4t65 swap into an older Wbody. That would help out tranny stability immensely but I thought the 4t65 was too big. Any feedback welcome.
