2001年6月4日 · It is my understanding that the ZL3 code was telling the line worker this was an upgrade from a base Malibu.Thus the RPO Z25 396. But the reason the Z15 LS5 or LS6 454 cars do not show ZL3 conv.on their buildsheet is because in theory you had to order the RPO Z25 upgrade first,then upgrade to the RPO Z15 454 option.Thus making ZL3 redundant.

2023年1月7日 · F40 and F41 are specific options beyond the specific SS base option. Documented in the Ass'y Manual. Also on the build sheet. F40 or F41 are listed separate on the build sheet. Z25 is an overall body conversion for SS 396 similar to Z15 for SS 454 conversion. It includes a variety of parts special to the respective SS option.

2004年2月12日 · * No ZL3 or Z25 code on COPO but shows engine as L78 * ZL3 CONV SS396 and Z25 SS396 code on L78 non-COPO car So, even if you took build sheets from 4 of the 5 plants for Chevelles, they aren't going to read the same but ZL3 and Z25 were the only two codes used on Chevelles in 1969. In 1970, only Kansas City used both ZL3 and Z25.

2010年11月30日 · {Edit} To answer the original question about Z15 or Z25 on 69-71 tags: 1. Z15 was not available in 1969, so no. 2. Of the few 1971 & 1972 Oshawa tags I have, the ONLY RPO code on them is C08 (vinyl top) when applicable, no other RPO codes that I've seen. That and the Z25 code was dropped in 1971 so no it wouldn't be on 71 or 72 Oshawa tags either.

2009年1月14日 · For 1971 and 1972, the Z25 option was dropped and the Z15 became simply the SS Equipment option and did not include a specific engine but did require an optional V8. Hence the 350-2 (L65), 350-4 (L48), 402-4 (LS3) and 454-4 (LS5) engines could be ordered with the Z15 SS Equipment option but no 307 since the 307 was the base V8 and not optional ...

2005年3月25日 · When I did the reasearch for my '68-'72 production totals poster, I concluded that 113 1969 Malibus were built with a 396 engine, but without the "SS" (Z25) package. I just spent the last week totally reconfiguring my home office (now with high-speed internet - yea !). Anyway, while cleaning...

2011年1月8日 · As Dale mentioned, some options are listed just becuase they are part of another package. The ZJ9 lamp group includes the CD2 washer jar monitor, U25, 26, 28 and 29 lamps, and the UM1 mirror lamp. B22 emblems and B96 wheelhouse moldings, and the front disc brakes, and the F41 suspension, and the L34 engine are all part of the Z25 SS package.

2005年1月2日 · Hey guys, Over the weekend, my dad, brother and I pulled out a 454 out of a '77 "Camper Special" Silverado Suburban. My brother's 69 Nova has a tired, old, borrowed-from-a-friend 307. So we're pondering doing a BBC swap in the Nova. We brought it home with the water pump, fuel pump, exhaust...

1999年4月26日 · My 70SS buildsheet also shows the Z25 SS 396 pkg and ZL3 SS conversion codes (along wih the ZL2,A51,D55,D88,F41,G80,G94,J50,JL2,L34, etc. codes which accurately id the car as a true SS). The car was a customer order as identified on the buildsheet. I also have the protect-o-plate that further ids the car.

1-8-7-2-6-5-4-3 is the firing order for the current LS1-style small blocks (Gen III/IV). 1-8-4-3-6-5-7-2 is the firing order used for the majority of small blocks (includes the LT1 and 96+ "Vortec" engines.) and big blocks (don't know if a new firing order is even used, maybe ALL big blocks use it?) as far as CHEVY goes.
