2seater Posted December 12, 2012 Share Posted December 12, 2012 I am pretty certain all 1988 engines have "3800" cast into the top of the intake plenum, and I am reasonably sure that the 1989 does not. I am asking if anyone has an engine that doesn't match this description and would let me know. I am looking for a visual way to sort out engines in a scrap pile. I have been looking for an '88 to scavenge the camshaft. Link to comment Share on other sites More sharing options...

D-a-n-i-e-l Posted December 12, 2012 Share Posted December 12, 2012 My 89 had the 3800 stamped on it. I am pretty sure it was the original engine. Link to comment Share on other sites More sharing options...
2seater Posted December 12, 2012 Author Share Posted December 12, 2012 Thanks guys. That is what I was afraid of. Stuff being phased in and there is overlap from year to year. I guess a dial indicator will have to be used on a couple of pushrods to find what I am looking for. Link to comment Share on other sites More sharing options...
padgett Posted December 13, 2012 Share Posted December 13, 2012 The 1989 Vixen SE all had the 3800 in the plenium. I suspect some were left over at the end of the year and since the engine didn't change... Link to comment Share on other sites More sharing options...

2seater Posted December 13, 2012 Author Share Posted December 13, 2012 I guess I will have to find what I am looking for the hard way. I wonder what other parts may have carried over or maybe even started early? The 1990 Buick Regal was the first to have the L27 engine, but of course that is visually different. Just for info. purposes, I found some information on the L27 camshaft, and it is even milder than the '89-90, at least on the intake lobe. The same exhaust lobe but seven degrees less on the intake lobe. Very strange and not what I would expect with a 5hp bump plus a little more torque. Perhaps the info. is wrong, the bump-up is fiction or it was done in some other way. The intake is obviously different, but the internals of the engine were exactly the same for the early L27 as the LN3.Thanks to all. Link to comment Share on other sites More sharing options...
