Just bought an 87 Elky with a 305 and 200-4r tranny. I know the ss monte's had upgraded parts (obviously). I was wondering what they changed on the SS Elky motor-wise as opposed to a normal 305.

Ehhh not mich difference at all. Now i know there are a couple 305's in elkies that got a bit more power.
This is what i have read......
305-180hp, 240lbs. Tq (Kw 75)
305-190hp, 245lbs. Tq (Kw 105)

Dont know what kw means... They both came in elkies the same year. I dont know if tere is a way to find out? I think is un common for the second one. You got the 180 hp 305 my best guess. The 190 was most likely an (HO) high output which would clearly be stated.

The SS for 5th gens was basically a body kit package. Nothin more. I wish!

No, the SS el caminos with the 305 did not have the L69 HO 305 like the monte carlo ss did, they had the run of the mill LG4 305, nothing special. So the conquista, SS, and base el caminos all had the same 305s. :beer:

I agree, SS just means cosmetic in 5th Gens.Decals,gauge pack,black chrome etc.

The 5th generation el Camino was available with a sbc 350 for 1978 and 1979 (and maybe 1980) designated as the L-48. Beginning in 1980 (and until the end of the EC production in 1987), the EC was available with the sbc 305 designated as the LG4. The Monte Carlo SS received the 305 sbc designated as the L-69. I have pasted the descriptions for the LG4, L-69 and the L-48 from craigslist as follows:

LG4 - Years: 1980–1987
The LG4 produced 150 hp (112 kW)-170 hp (127 kW) and 240 lb·ft (325 N·m)-250 lb·ft (339 N·m). The addition of a knock sensor for the engine management system in 1985 allowed an increase in compression and a more aggressive spark timing map in the ECM. As a result power increased for the 1985 models to 165 hp (123 kW) from the 150 hp (112 kW) rating in 1984.

L69 - Years: 1983–1986
The L69 featured a compression ratio of 9.5:1, heads from the LU5 engine and the camshaft from the L83. Additionally the engine came equipped with a dual snorkel air cleaner assembly, aluminum intake manifold, aluminum flywheel and a knock sensor which allowed more aggressive spark timing. This engine produced 190 hp (142 kW) @ 4800 and 240 lb·ft (325 N·m) of torque @ 3200 rpm.

L-48 Years: 1967–1980
The L-48 is the original 350 cu in (5.7 L), available only in the Camaro (1967-up) or Chevy II/Nova in '68-79. In '69 it was used in almost all car lines; Camaros, Impalas, El Caminos, Chevelles & Novas. 1969 L-48's use a Hyd Cam, 4bbl Quadrajet carburetor, cast pistons, 4-bolt main #010 Blocks & #041 or 186 heads. Power output was 300HP and 380 lb·ft (520 N·m) torque. Compression ratio was 10.25-1. The compression ratio of the L48 was lowered to 8.5:1 in 1971.

In 1972 the only way to get a L-48 (4bbl V8) in a Chevy Nova was to get the Super Sport Package. This is indicated by the 5th digit in the VIN being a "K". 1972 was the only year you could verify the Super Sport package by the VIN.
The L-48 V8 was the standard engine in the 1975–1980 Chevrolet Corvette. The L-48 V8 Corvette engine produced 165 bhp in 1975. Power increased to 180 bhp in 1976 and stayed the same in 1977. 1978 saw 175 bhp for California or high altitude areas and 185 bhp for everywhere else. Power increased to 195 bhp in 1979 and decreased to 190 bhp in 1980.

Personally I think they should've only called them ss if they had the f41 package and a ccc console shift with 8.5 342 posi but hey we can all dream

ss in the 5 gen just stood for super sexy. if you wanted to special order better gears or dealer installed l69 you could.but they were mechanically changed very little. the line was dieing off and didnt warrant much r&d.but it is a chevy and is only limited to your wallet size and imagination as to how far you can take it

When Dad and I were sitting down with the dealer to special order the 85 I know own, we asked about packages and such. We passed on the Choo Choo SS because it was appearance only, no performance upgrade. Dad also passed on the SS appearance package for that reason plus lack of chrome. We ordered a blue Conquista with 305, 200C, and F41. Had he known we could have gotten the Conquista chrome without two tone paint, it would have been solid dark blue. According to Sealed Power and Walker, the big difference in the 305 'G' and 'H' is cam and exhaust. The Monte SS 'G' code had a 202/207 with .403/.414 lift, on a 114 cl. The 'H' had a 176/194 with .234/.257 lift on a 112. That's a pitiful little cam. The other big difference is the MCSS had a higher flow converter with 3" oval inlet and outlet (probably helped a lot) which required a different Y pipe assembly. This connected to a mid pipe that is 2 1/4" and splits to two 2 1/4" muffler/tailpipe assemblies. The Elco and non-SS Montes got a more restrictive converter with 2 1/4" inlet and outlet into a single pipe and muffler. Which makes me think that when it's time to upgrade mine, I'm going to use Monte SS downpipes, converter, midpipes and taipipes. I would use something like a Walker long case muffler to fill the gap from longer wheelbase, and run all this as either Dynomax or Magnaflow performance upgrade parts to keep it stock looking and qiuet. Later i would either swap cams or go for a 350 or 383, swap transmissions and possibly rear gears. Patrick.

My Elky came with a transplanted L69 engine and exhaust from a MonteCarlo SS AeroCoupe. The exhaust fits well, except for the difference in overall length. You can see where the PO welded in extra pipe to make up the difference. I replaced the exhaust manifolds with TES headers from a MC, and they fit perfectly. I replaced one of the tailpipes ( muffler back) and again perfect fit.

One of the exhaust companies sells a kit that includes the extensions for the Elky.

I was also lucky that this engine was from an '87, so I was easily able to convert to Roller Cam. Boy, an LT1 cam works wonders!
