Not a BBC vs Cad.
Gary, I think you took my post out of context. The Grandma's Cadillac statement was merely used as an example to show that building big torque numbers can be achieved without big horsepower. Not BBC vs. Cadillac. Nolan

|1Gary||I don't think you can compare a caddy to a 454.If memory serves me right,rod ratio's are all different and when you want torque that matters abunch.The caddy needs $$$$ aftermarket heads and still is limited in RPM where the 54 needs RPM.308 intake runners would do it for a 54 along with a matching cam to SCR's.|

this was the first 600 pounds/foot torque engine in the list.
so a well tuned 530 horse power 454 could do this. I was comparing my combination of a 600 horse 540 I was aware of that made 640 pounds/ foot of torque
thanks for that info

454'S Nearly or Over 600 ft.lbs of torque
It doesn't take a 650 hp 454 to make 600 ft/lb of torque. Here are a bunch done by the same builder;
Chevy 454 - 475 hp Crate Engine Big Block Turn Key from Phoenix Engine
Grandma's 1970 Cadillac 472's and 500's made 525ft/lb and 550ft/lb respectively. These were engines so quiet and smooth you couldn't hear them running. These only made 375-400 hp;
Kenny, if you want to build big torque you have to think smaller with everything in the combo except CR. Nolan

|vinniekq2||you would need a 650 plus horse power 454 to make 600 pounds/foot torque, or boost|

|ap72||It says 600lbs, I'm assuming he means ftlb and that's pretty damn hard to do actually.|

|RWENUTS||You can't say 600hp and mileage in the same sentence!!|

peanut port heads for the street
I totally agree, I think for the everyday street only guy it will give the best gas milage. I've read that even with the port mismatch at that power level, there is no problem with the mismatch. For saturday night fun in an early camaro, or truck for that matter is all I'd need to make me happy. This might be my next build project for old pickup truck.
