Revise that I was thinking Flywheel HP. you will probably be in the range of 175-225 at the wheels.

175 isn't that stock 5.0 numbers!
Has the roller cam so much to say?

I would say 240rwhp If it was a stick car it would be about 30 more then that. I have seen AOD's take 50 more rwhp to run over a 5 speed but the C4 won't take nearly as much as the AOD. If you only make 175 with that combo then something is majorly wrong somewhere. Let us know as soon as you run it.

I will let you know.
Hopefully in 5 weeks time. Just have to come home from the big ocean and put in the new cam and crank i have ordered from the states.

Who's Dyno? My numbers would be on a MD not a Dyno Jet. My 347 which is alot more motor than this one described is only making 280 on the MD but running low 11's in a 3300# car.

I don't know what kind of dyno they have. But it's in Norway
Maybe they have a european one. It's a Bosch shop

Their are a bunch of different ones and they all rate a little different way. I don't have a clue how it would rate in Europe or What type of Dyno they might have? But don't be discouraged by the low sounding numbers, its how the car runs not what it lays down on one of those chassis dynos, they are better used for tuning and finding HP. Like I said my 347 has a whole lot done to it and runs like a scalded dog but dosent lay down the dyno numbers. It's outrun alot of cars rating well into the 400-500 range on other dynos !!

I'd think 250rwhp should be pretty close. The heads have a lot more potential than what you're using with that hydraulic cam, and also a lot will depend on how choked down your exhaust is, but 250 sounds like a good guess to me.

That is why they always tell you never race a dyno. You can't ever tell by just looking at a dyno sheet what car is going to be faster at the strip. Just mainly use the dyno as a tuning tool.

250 sounds about right. And yes the dyno is only a tuning tool, I think people put too much emphasis on how much horsepower they have, not how fast their car actually is.

270RWHP. I pulled 250 from an untuned similar setup using Roush 200's and a similar cam (Xtreme 268H)

My '66 Mustang used to have a very similar combo last fall.
302 with cast dished pistons
650 Demon VS carb
Edelbrock RPM intake
Comp XE268H cam 224/230 @ .050
Hooker 1 5/8" headers
C4 with 3000 stall
3.55 gears
I never had it dynoed but it ran consistent 13.2's at 102.
Yours may not dyno well but it should run pretty good for a fun street and strip ride.
