Estimated HP and Torque sbc 355, please
 
Hello, big fan of the site and its educated users. I am wondering if someone would like to run my setup on an engine calculator in order for me to select a few more parts for my car. If so I will post the details of the engine and drive terrain, if not then i wont, lol, i will check back shortly for replies, again thank you.

If you want someone to do it you might as well go ahead and post all the parts involved. JMO

No problem.
It has it at peak hp 389 @ 5500rpms, and torque 409 @ 4000 rpms.

AR_Racing_627 08-10-2011 05:02 PM

alright thanks, i know it pulls pretty good but was unsure of what i really had, i was thinking about going with a little more cam and 2500 stall converter

cool rockin daddy 08-10-2011 08:20 PM

Dang, I didn't even have a dyno sim when I made my post.

AR_Racing_627 08-14-2011 12:44 PM

well u were pretty darn accurate lol

Right now I'd do something about that rear end ratio before I stepped up to more stall and cam. 3.55 or 3.73s would make it pull like a freight train in comparison. You're going to need more gear if you want to step up the cam and stall anyways, especially in a big heavy monte carlo.

Btw, nice guess CRD. :thumbup:

FmrStrtracer 08-14-2011 02:44 PM

If its a dirt car, isnt it stripped down? 4300lbs seems heavy if its stripped.

AR_Racing_627 08-15-2011 05:05 PM

its a figure 8 car so i have lots of steal welded in it including a 12" by 5 1/2' I beam for a rear bumper, so she weighs in.
I'm running the 3.08 gears for lower rpm's i had the 3.73's in it and she wrapped out way to quick.
