Thread: LT intake manifold modification for distributor

Tweet

Roger-basicly this just moves the rotor/cap part to the rear of manifold--with the later years LT there is a more modern sensor in the timing cover so that and the fact that the 1996 and up ( on all vehicles OB2) are much more advanced than the early ones-----I think that most of the problems people had with opti was self induced-washing engine with high pressure washer, etc-also there was a vent system tied into the intake manifold and air cleaner so clean dry air would circulate but when pepes put fresh cold air intakes, etc , etc they lost the oem system of the vent-then the heat/cool cycles probably created a vapor/condensation issue-------My distributor will just be a rotor/cap with the coil, timing functions still done by the PCM.
However I am doing one for a guy that is taking off a coil/plug like the new LS engines as it didn't meet expectations and he will be doing his with a FAST XT? instead of the oem-(oem is limited to 6 or 7000 rpm)


Duece, if you haven't changed the intake or exhaust its not a hot rod??????????
I believe that the LT water pump being driven from the cam is more compact than the older engines by eliminating another pulley. the issue with my install into my wifes 33 is that now that we want to add a/c, we need something on each side of the crank and to lower them (alt, a/c) enough to clear the wire terminals of the opti gets down low and close to steering stuff. I have thought abought driving alt off tail shaft but if we run air will need more amps/mile and in slow moving traffic probably wouldn't keep up. If you have looked at front of LT1 engines, keep in mind that there are different length lower pulley/dampners from various installs-vet, Camaro/firebird/buick/impala/etc
