HP and Torque estimate

[Cutlass92]

Hey I’m new here so I apologize if I posted this in the wrong section but I just wanted to see if I could get a HP estimate preferably wheel HP but crank HP is fine. So the engine is a Post 1987 TBI 350 with the 191 stock heads which I know don’t flow worth crap it’s been converted to carb a Holley 600 Edelbrock dual plane intake hooker mid length headers XE 262 cam from comp cam .462/.469 lift. Dual flow master exhaust 2 1/2 inch pipes TH350 trans and 3.42 gears. Stock engine except for these mods. I know with those crappy heads the HP May not be that high but I know those engines make good low end torque and that’s really what I’m looking for gets sideways and burns rubber through 2nd gear fairly easily. So if anyone can give me a HP and torque estimate that would be great. Hope to hear you guys feedback and maybe some tips moving forward thanks

You would be doing good if you are getting 300 - 350HP. Will very depending on internals. Drop the carb and do fuel injection and you would get a little more HP.

Thanks for the input. I think the stock torque estimate for that engine was right at 300 ft lbs how much more torque do you think it’s making. Again it’s a stock engine besides the carb intake cam headers and exhaust system

Have to know all the number. Torque is a mathematical Equation based on HP, gearing, transmission, torque converter and so on.

I doubt the dTBI "swirl port" heads will support more than 300hp without quite a bit of mods.  And I'm guessing 325-350 lbs of torque with your mods.

 

My 91 K2500LD with a NV3500 with the "road" gears (no granny low) and 3.73 gears would smoke the tires in first and sometimes keep them spinning for a second or so when I would grab second.

I have a modified 92 TBI engine in a 92 truck. If I was in your shoes I’d go to swap meets look on-line to replace the heads as long as the engine is in good shape. My truck has dart aluminum heads.
