maybe2fast Posted November 10, 2004 Report Posted November 10, 2004 this is going to be the beginning of many questions... I hate to hoe out my buyer of the SC I have for sale but...would that SC off a 1999 L67 fit on the 1990 3800? I don't know the difference between the SC motors and the N/A motors. Are the lower ends stronger or what? this maybe a worth while project! Quote
cutlassdude96 Posted November 10, 2004 Report Posted November 10, 2004 I would just find a compleat sc motor Quote
DiscoStudd Posted November 10, 2004 Report Posted November 10, 2004 The injectors on the Series I L67 are mounted in the lower intake manifold. On the Series II L67's, the injectors are mounted in the heads. If you bolted up a Series II supercharger to an L27 block, you'd have nowhere to mount the injectors (and the heads are incompatible as far as I know...) Quote
maybe2fast Posted November 10, 2004 Author Report Posted November 10, 2004 Okay, my bubble is popped. lol Quote
White93z34 Posted November 10, 2004 Report Posted November 10, 2004 i'm imagine a first gen L67 swap would be prety easy in a car that already has the gen 1 3800. Quote
maybe2fast Posted November 10, 2004 Author Report Posted November 10, 2004 my thoughts exactly...what PCM would I used? Quote
99RegalGS Posted November 10, 2004 Report Posted November 10, 2004 this is going to be the beginning of many questions...

Are the lower ends stronger or what? this maybe a worth while project! The only difference between the series 1 L67 and the Series 1 L27 are the intake manifold, connecting rods, and a differently balanced crankshaft (because of the different rods). The injectors on the Series I L67 are mounted in the lower intake manifold. On the Series II L67's, the injectors are mounted in the heads. If you bolted up a Series II supercharger to an L27 block, you'd have nowhere to mount the injectors (and the heads are incompatible as far as I know...) I'm not sure about the dimentions for the M-90 but I'm assuming they're the same it not close to the M-62. The reason why the injectors in the heads on the series 2 L67 is because the series 2 block has a shorter deckheight, so the distance between each bank of the engine is less. hence less space for a s/c and the fuel injectors. so the injectors had to be moved because there was no space. my thoughts exactly...what PCM would I used? you could have just grabbed a chip from a 92,93 (maybe 94,95???) Bonneville that had a s/c. Quote
