Guest 240SBB Posted October 3, 2003 Share Posted October 3, 2003 Unless you plan on rebuilding the thing with high performance parts, you'll probably be better off finding an earlier 350 (1972 or back) with higher compression. Here's a link to some helpful information regarding a 260Z with a 180hp 350: http://www.jagsthatrun.com/Pages/Datsun_Z_V-8.html Quote Link to comment Share on other sites More sharing options...
Pyro Posted October 3, 2003 Share Posted October 3, 2003 The 77 350 from a truck or a vette is your best bet (180 to 190 hp). A 77 350 from a passenger car will be a dog (150 hp but 300 ft lb torque). However, a set of 64 cc vortex heads, vortex performer rpm intake, 750 holley carb, and a cam will make 400 hp very quickly. I think you should install the low HP motor for now because there are a lot of things to do before you get the car driving (mounts, cross members, cooling, drive shaft, wiring, exhaust, shifter, etc). Then later upgrade the HP for about 1000.00 with the above mentioned items. However, use the hooker block hugger headers (PN 2100) with a single 3" exhaust on the low HP engine so you won't need to upgrade the exhaust later. Please get the JTR manual before you start your conversion. Another option would be to keep the low hp engine and spray some N20. I have seen junk yard motors make 500 hp with a 300 shot of N20!

baddriver Posted October 3, 2003 Share Posted October 3, 2003 You're probably right that the horsepower is under 200, however that's still a good step up from the six and will make a fun, fast, and inexpensive V8 z conversion. If you are looking to build a good car thats a lot of fun to drive without spending a fortune, this would be the way to go. If this is a four barrel, than it probably has 1.94 valves, and decent heads. It will have a high-torque, low horse cam. You could install it as is or change the cam out and have a little more RPM. I wouldn't use a 2 barrel, as the performance is lower, and the fuel consumption is worse, plus 2 barrels usually had the smaller valve heads.
