Hey whats up.. I built a 383 stroker and put it in my 67 Camaro and im trying to figure out what kinda of power my engine is putting down.. Its a Speedomotive 383 Stroker kit all forged
around 10.13:1 compression
It has a Trick flow Top end kit.. its the one that says 465hp and 450tq..not sure how accurate that is.. this is the link to it http://store.summitracing.com/partdetail.asp?part=TFS%2DK314%2D465%2D450&autoview=sku

I have a Edelbrock Vic Jr. manifold on it with a Demon 750cfm carb..
if anyone has any ideas of what its making to the rear wheels i would appreciate it if ya share your guess with me..:beers:

Oh and heres some links to some Pics..

That's probably pretty close.

yea i was hoping that.. what do you think the rear wheel power would be.. im going to dyno it at school in a couple weeks so i wanna prepare

After you put it in the car, hook up the accessories and in-car exhaust system you're probably peaking at about 430 hp, so I would predict about 345 peak horses on a Dynojet.

General rule of thumb is 20% loss on a chasis dyno compared to the engine dyno. So if your engine is putting out 465 hp and 450 tq on the engine dyno, it's safe to say you should get around 372 hp and 360 tq at the rear wheels. Remember this is approximate.

That would work if you installed the dyno exhaust system in the car, as well as the dyno cool air intake, electric water pump, electric fan, etc. We've dynoed some of a local vendor's 440/440 383 builds and find them to be quite a bit less as installed in the car. One in particular I recall was a big disappointment to the owner, only providing 295 hp to the rear wheels.

Yeah, you're right. There are many different factors that go into the final numbers on a dyno run. That's why if you want more HP and TQ to the wheels, you have to drive less accessories off the engine.

If you want really big numbers at the wheels, throw a blown bbc in there. :yes:
