hello,

Just wondering how much hp and torque i should be seeing with my combo. Supposedly desktop dyno says somewhere around 313 hp and 464 ft lbs of torque at flywheel.

1992 Camaro RS,

2.5 inch true duals with magnaflow muffler, not mandrel bent
hedman shorty headers- 1 5/8 primaries
350 roller block, dished stock type hypereutectic pistons -12cc)
comp xe258 roller cam,(.480 .487 @.5", 206, 212 duration at .5")
modified 081 heads (3 angle valve job, ported, polished, comp 981 springs, 1.94", 1.55" valves)
Holley 6210-3 650 dp ,
performer intake

 

I'd say it depends on how good your heads actually flow.
To say they are ported and polished doesn't mean much, flow numbers are the tell-tale.

I could see you having 300+hp, but I don't know about 464 ft-lbs, I'd say closer to 420 ft-lbs or so IMO.

 

i did a pretty thorough porting of the heads, dont no much about flow numbers though. I just wanted to see what other people thought

thanks

 

I would have to aggree I would think that you are right at about the 300 or so HP mark but 464ftbl's would be something that a 383 would be putting out. I would tend to think right around 390 to 420ftlb's. Just my thoughts.

 

That will be a very torquey setup though, very fun to drive.
You can almost get away with those 2.73's (almost!). With a TH350 i'd step up the gears, or else it'll still be fairly sleepy off the line.

That's a WEE cam. But healthy lift alright. Should be great on the street. If you're ever in Calgary we'll have to line 'em up.

 

yeah sounds good! what kind of gears would you guys recommend. I will be swapping in a th350 in the spring which is built up to handle the torque, with a 3000 rpm stall.

yeah sounds a little too high, thats why i asked u guys

 

Is this much of a highway car at all?
You don't have enough cam to really use that much gear, so maybe 3.23's or so.

 

i don't really travel on the highway so i was thinking either 3.43 and 3.73's being the max and not more than that.
Once I get the rear end done, thats all im going to do with it until it blows up so I think getting the 3.23 in there would be sort of a waste because i wouldn't be able to do it again cus of funds.
