BTW, I'm still trying to get a factory service manual ^^^^^^^^^^^^^^^^^^^^^ Hmmmm, in the G.M. high performance catalog they list computer units with and without VATS and define VATS as Vehicle anti theft system. I guess maybe it depends on which book you look at. 8-? >for the '89 TPI 350. > >Keep in touch, and good luck on your swaps.

It had 182,000 miles on it and the reason it came in was a piece of the spark plug lodged under the valve and chipped it. The plugs had been replaced 1 time in 182,000 miles! On a 4cyl truck! Needless to say the center electrode insulator was all but gone in most of the bosch plugs, along with a good part of the electrode. Nice looking head! Think somebody can throw a multiplier at the cad machine and make that head fit a 460?(No, I don't believe anybody would, but I do believe they could!) ------------------------------ End of DIY_EFI Digest V1 #169 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
