Hi JoJoe,

I will search more later on Spec`s...Go to end of post for link.

1985 Chevrolet Monte Carlo

Rare in Chevrolet sales literature were performance figures, but for 1985 Chevrolet published the following specifications for the Monte Carlo SS: 0-50 mph in 6.0 seconds, 0-60 mph in 8.4 seconds, standing 1/4 mile, 16.1 seconds, lateral acceleration of 82 g. For the base Monte Carlo, a new engine, the 4.3-liter V-6 with throttle body fuel injection, was standard. Optional was the 5.0L V8. Also available was a new 4-speed automatic transmission in which 4th gear was a .70:1 overdrive. The basic body and interior design for both the base and SS Monte Carlo remained the same as the previous year.
1986 Chevrolet Monte Carlo
As Chevrolet Started to produce 1986 Monte Carlos, it can be noted that the same body and front as last year was just carried over. It comes in 3 trims to which are the LS 2-door Coupe, Sport 2-door Coupe, and SS Sport 2-door Coupe. Introduced later in 1986 was the Luxury Sport Coupe, which included new front end, rear tail lamps and bumpers. Up front, the four rectangular headlamps were replaced with single composite headlamps molded into a new, smoothed, grille and bumper design. In the rear, the tail lamps were enlarged and molded into a smoothed rear bumper cover. The SS remained unchanged for 1986, except for the addition of the Monte Carlo Aero Coupe, a modification that included a drastically sloped rear window and short trunk lid. Only 200 Aero Coupes were produced for retail consumers in 1986; exactly the number necessary to allow NASCAR racing teams using the Monte Carlo body to legally make the modification to their race cars. This modified version of the SS improved the aerodynamic performance of the car high speeds like those attained on the NASCAR super-speedways.
1988 Chevrolet Monte CarloIn the last year of the fourth generation, MC, 1988 model year marked the end of an era. The Aero Coupe had been dropped. The Monte Carlo was made available in LS Sport and SS sport versions only. The former has a standard engine of 4.3L 140 hp V6, and latter has 5.0L 180 hp V8, but both have a 225 lb-ft torque.
The 1988 Chevy has a maximum seating capacity of 6. Sunroof, air conditioning, power window and power door locks, and cassette player are optional for both trims. For its review, 38 consumers gave it an overall rating of 9.1 for 10. But after approximately three months of production, Chevrolet opted to completely cancel the Monte Carlo model. Sadly, production of the Monte Carlo ceased by the second week of December, and that will be the last time anyone would see the Monte Carlo for seven long years.

I haven't went all out looking for specs on these cars. I'm not sure what other info you're looking for? Have you looked in one of the '86 Monte Carlo sales brochures for additional information?

Unless you decode the RPO code list attached to the inside of the trunk lid there's really no way to find out exactly what your car came with. Like the specific gear ratio. The codes are out there. And one of the restoration packets from Chevy do help with learning about your car.

 

most of the LS monte's came with 3.73:1 with the 305(lg4) and the 200R4 trans the earlyer monte that came with the th350 had 3.42:1
and that is with the 305(lg4) motor as no LS,CL that i know of came with thw 305(L69 monte SS, camaro Z28 motor )
and i know that some motes in 86-88 came with a 4.3 F.I motor but don't know what drive train folow's ?
ans some earlyer montes came with the 3.8 buick motor (first version of the 3800) but not sure of what drive train folow's ?
and other G-body's used diffrent motor,trans,rear combo but i will leave it just monte for now

 

does any one know if an 85 regal frame will fit under my 84 monte cl?,and if so ,does anything have to be changed on that regal frame before i decide to put it under my monte

 

I'm pretty sure all G-body cars got the same frame under them. A salvage yard could confirm the information for you with their cross over books.

The Monte, Cutlass, Regal, &GN should all be on the same frame.

I've never seen one but I wonder if any LS Montes got the diesel engine in them?

 

yes the monte carlo CL did come with the 350 olds diesel motor but i think it was just for a year or maybe too
