If you truly want to go fast just drop a 305 LG4 into it

























I'm JUST KIDDING.. if anybody takes this post seriously I am gonna kick them in the teef!
Now.. carry on with the BBC posting

 

True, unless it's still in the original car. 1968-1969 only the 472 was available. 1970-1974, the 500 was only in the Eldorado, and maybe the 75 series as well but I'm not sure of that. 1975-1976 only the 500 was available. after 1977, you get into the 425, and then the 368 after that. They look the same but don't be fooled... they're not.

 

for a second, i was convinced on doing a caddy 500 swap, also. i have a 77 seville, which if you know anything about them, had the camaro/nova chassis under it just stretched out wheelbase. what i found, is that 500's are what everyone is looking for, the 472, though nearly the same motor, is practically worthless. nobody wants the 472, if they are going to do the swap, they are going all the way. they are identical externally, so theres really no guarantee of what youre getting until you id the crank, even and eldorado may have had the 500 pulled at some point and replaced with a 472. when doing the swap, if you are using stock exhaust manifolds, you will need the deville drivers side one, which is pricey, even on ebay, and you will need the eldo oil pan, which is also pricey. i had my 500 sitting side by side with the 350 chevy, and it is extremely huge compared to the small block. it looks like a v12 sitting next to a v8. id imagine with the small confines of a 3rd gen engine compartment, you may run into problems with finding room for the radiator and fans to fit after the motor is in there. if you are going to use the caddy motor in 100% stock form, you will make good power on a budget, but if you plan on upgrading it with a better cam, intake, carb, headers... you just lost the whole point of using the caddy motor, because now you have spent a ton to make the same power you could have made with a chevy for less. if money isnt an object, and youre doing it to be different, then go for it. theres a reason why you dont see a ton of cars with caddy motors in them, they have a limited supply of parts and any performance part is outrageous. they are awesome stock, thats about it.

 

I wouldn't say "nobody" wants them. Sure, if you don't know your Caddy big blocks, the allure of the monstrous 500 cubes seems like the better choice. That's not always the case.

In my previous post I mentioned an early 472. Early should be defined as the first two years, '68 & '69. If you compare a 472 and a 500 from the same year, then yes, the 500 edges out the 472. If you compare all years of the 472 and 500, you'd find that only the '70 and '71 500 beats out a '68 or '69 472, and the '71 by only a small margin at that. Every other year (72-76) of the 500 falls short of the factory ratings of the '68 & '69 472. Again, we're talking factory ratings. Start modding 'em and of course the bigger cubes will net better results. But like you said, then you loose the finacial advantage of just using a stock Cad BB.

 

I found a 91 RS for $3000 good condition[thinking]a z28 $4500 ok shape,and am gonna start with beefing the frame up first no matter what motor i get.My friend has a 12 bolt truck axle for sale not sure if it would fit,i cant seem to find the stock camaros axle width just gear ratios.Is the stockers weak point the housing or the shafts,becouse MOSER has a 30 spline shaft upgrade and the housing can be braced for cheap.About the caddys compression ratio wouldent the VIN # say if its the 10.1 or the 9. here is a cool link for a ls1 swap

1968 10.5:1, Second character in VIN is an 8

1969 10.5:1, Second character in VIN is a 9

1970 10:1- both 500 & 472, Second character in VIN is a 0

1971 8.8:1-472, 9:1-500, '71 had no model year I.D. character in VIN (Second and third character in VIN is 93 for an Eldorado)

1972 8.5:1- both 500 & 472, Sixth character in VIN is a 2

1973 8.5:1- both 500 & 472, Sixth character in VIN is a 3

1974 8.25:1- both 500 & 472, Sixth character in VIN is a 4

1975 8.5:1- 500 (472 dropped), Sixth character in VIN is a 5

1976 8.5:1- 500, Sixth character in VIN is a 6

*edit* All years listed above have the VIN stamped on a pad on the upper rear area of the block. (behind intake)

 

I read on here somewhere that a stock LS1 can dip into the 12.00's 12.70ET with ram air or something BS or fact? maby some gears? There is a 2001 LS1 with 6 speed trans in a auto trader 11k miles??hmm can never tell,no price waiting for callback.What would you pay for it.

 

So the 75 deville engine wouldent be all that great with only 8.5:1 compression,but NOS dosen't like high compression anyway,So $1000 500ci motor/150-200 shot of nos/couple hundred$ = great cheap fun.Frame,axle,tranny first ofcourse. your thoughts

 

doubt that car will be cheap with that low of miles, but if you are wanting to give your buddy a run in his 2006 roush mustang, i hate to say it, but your best choice is an ls1 car. they have came way down in price, and the drivetrain is awesome in stock form, it only gets better from there. problem with competing with him using an old car is, if you can beat him in the 1/4, hell beat you at top end, mpg, or handling. if you take a newer ls1 car which can be found for under 10k all the time, you have most areas covered already, all you have to do is add a little more power and hell be chasing you in all categories. check out the ls1 sites, and portion of this board, im sure youll find out quickly what they are capable of, and what little it takes to get there. keep in mind, if he can afford a roush mustang, you will probably only beat him once before he goes out and buys something else to make his car faster than yours.

 

The auto trader 2001LS1 listing is just a motor and tranny must be from a wreak.The 4th gen camaros look ok with proper rims,hood ect.but i'm all obout 92's and I havent seen a 2000 for under $15000 thats when the LS1 got better right.
