Lets see what you all have to say about the "other" GM engine families. Give us the low down on what it takes to get them to work in a 4x4. What are the advantages and disadvantages of running one off road.
Just pulling the numbers from one of my resources... that is what they had at the time(Chilton) I can't make any assurances as to the accuracy of them. My second different source(thick book at library) and a third resource(Big Inch Cadillac) rates them at [email protected](efi or carb made no difference in torque... hp "jumped" to [email protected])Chief yelling alot said:
the 425 maks 320 FLBS at 2000 RPM
well its kida funny but also Chiltons 1979 Motors for 1980 had the same numbersLil'John said:
Out of curiousity, where are you getting your rating?
Ahh... I see what happened then. The number I quoted was the first year of the motor. I looked at the 79 ones and they had higher numbers Odd thoughChief yelling alot said:

He's on his second 500 Caddy.
He also wore out the D60 rear and is now running a D70 and duals.
4-5mpg.. and with both rigs on the 30' trailer, doesn't pull up hills as fast as it used to with the single trailer (duh), and with the camper thrown in, wind sucks..
But he seems to be happy with the Cad motor, backed up by a TH400, into the (stock) divorced '205.
Well, that same friend with the 500 runs Chevys in most of his other stuff.. including a 14:1 454... but for some reason he opted for the 500 for his tow rig.charlo said:You gotta respect a man who runs a caddy 500(or 513). But for the money cant you get more power from the chevy stuffs.
For a better comparison to your numbers above, lets use the EFI 500:charlo said:You gotta respect a man who runs a caddy 500(or 513). But for the money cant you get more power from the chevy stuffs.
89 454 = [email protected]????rpm and [email protected] or so rpm
87 350 = [email protected] and ???
I guess these numbers arent fair because of the FI but parts availablity and price make these fairly similar numbers look a bit better than the caddies numbers. The caddy takes the lead by far in the bragging rights category.
I had the heads machined to pro-street specs with oversize valves
I had the stock intake ported & polished for better specs.
I had the quadrajet carb rebuilt & jetted
I put in a 300T cam
I added forged rods & Pistons
I added a Stage II rocker set
I added an HEI system
The block was bored .60 over to 507 CID
