Good torque cam
I'm doing the whole cam selection thing now and wanted a couple of good "torquey" cams. Im not looking for a specifics so thats why I havent given alot of info. What are known as a good torque cam. Something along the lines of 400rwhp/400rwtq or 400rwhp/4xxrwtq. Low end smashing power.

400whp/400tq is gonna be hard to come by on stock bottom end LT1 motor. You can make 400whp but torque will be in the 350-380 range depending. A 383 Lt1 has a much better chance at 400/400
else run a nitrous shot and get more like 400/500

Gonna be a REAL hard, but if you go FI or NO2, then you should get close. Then lies the problem of longiveity. My question was pointed at, what other than a cam are you expecting to do in order to acheive your goal, because it's going to take more than just a cam to get to those numbers! Ask questions, think it out and think package not just cam!R/Noland

According to a few sites for LT1 buildup I've come across, the "Edelbrock package" seems to do almost what you're trying to do. It has a Performer LT1 cam, which basically is an LT4 hotcam, along with their performer heads to make a stock LT1 bottom get nearly 400flbs of torque and 380-390hp. Doing so, will raise peak torque and power around 5-800 over stock, which is something you're not looking for.
Now I don't know what heads you have now, or if you plan on changing them, but if you go to a nice set from Brodix or Dart and choose a cam with similar lift but with less duration, it would get you near your goal. A roller with .520-.530 lift and something like 205-210 duration. You could run a bigger cam depending on heads, but keep the duration down if you want low-end.
CompCam's Thumpr series are known for generous amounts of "under the peak" power and torque. They might be something worth looking into.

You need to stroke that thing, no way youre going to get that at the tire with just a cam. If you did with H/C intake, etc it would be a bitch to drive and the numbers would be high in the powerband.

Yeah Im not tring to get in the whole age old battle of 400rwhp. I just wanted to know what the best torque cam we can put in a stock shortblock. If I blow it up so be it and 383 is on its way.
My set up is being put together right now. I have so far 58mm TB, Port Matched lt1 intake, Going with 195cc 210cc Heads looking into that now either AI,LE, or custom, Melrose 1 3/4 headers into 3 inch cats into Corsa exhaust. I will have the fuel to feed too. Im scouting parts out now. Trying to find the right cam and head combo now.
I just see ALOT of people with stock bottom ends making 400rwhp but the torque is like 360rwtq. Im looking for more torque for my car. IE 400rwhp/400rwhp is my goal. Goals are what you aim for and hope to get close.
Basically with every single possible supporting mod you can think of already on a stock shortblock car minus a cam. What cam would give a lvl hp to torque ratio.
Most likely I will blow the motor and Im completely fine with that. That means I get to buy bigger toys. Thanks

taht new HSR designed for LT1's will help boost torque. Runner length is more torque friendly.
I've seen a few 400/400 whp/wtq 383 LT1's and basically any stage 2 or so setup from LE or AI will get you there.
On a 350 you will still make solid torque. just not 400. But close enough could be all you really need.
general points are keep intake to exhaust duration split tighter. Too much will bleed off lower rpm cylinder pressure and less torque is made. Same with overall overlap/lsa. Too tight with too much overlap will favor top end and sacrifice torque. Good heads with a slightly smaller cam wil make the torque and get your hp in the 375-380 whp range. Thats pretty good. bigger cam in the 230-232 intake duration range should get you 400whp but i think the torque will be 360's-370 on a good day.

Right on thats the kinda response I was looking for. Thanks for your input. What do you think of this cam......238/242 .555/.563 113 LSA with 1.5 rockers? With a 1.6 lift should be around .585/.593 area.

I'm thinking that much duration is better suited to top end rather than torque.Need to shorten the duration
