Engine RPM, what to expect?

the car will run 3-4 thenths faster w/ 3.91's. I'll put a $20 bill on it.

383duster/Martijn,

You built my transmission. In your honest and professional opinion, do you think my tranny will be able to handle 11.99999? If you think it will, I'll go for it and choose 3.91, because I need every thenth. If you think it will not, I'll choose 3.55 and will not run on slicks to reach the goal!

My vote would be for the 3.55s. You should EASILY be able to run 11.99 with what you have. Expect it to be faster than that , traction permitting of course. Cam is a bit small for a 493, should be a torque monster tho.

That cam would do 6k tops and make peak power at near 5500 in a 440. Up that to 500 cubes and that cam is gonna make that engine a real torker. If it was a 440 I would suggest 3.91's, but I think since you're not going to be able to rev that engine terribly high to get power out of it, you would be better off with the 3.55's.

Hi there Rob, Mike in New Zealand here.
I have an Australian Charger with a 493ci stroker.
The car weighs in at a little over 4000 lbs with me & a tank of gas.
I run a New-Process 4-speed & Ford 9" out back.
It has 2:75 gears;Yes,2:75; & it does a 60ft of 1:92-2:00 secs & the 1/4 is always around 12:15-12:25@117-118:50mph.
Now the combo is 440 Source Stealth Heads(no slower than Hughes Engines stage 2 Iron Heads;had them on before). Comp Cams 294 Solid(248@050");Weiend Xcelerator Single Plane;10:00 comp: which gives 193 lbs cranking pressure installed straight-up; 1-7/8th Headers & 850 D/P for the Drags. I just swap it over for a 650 D/P for on the street.
This combo gives me 17 miles per gallon imperial(about 19 US per gallon).
I would think hard about using that cam as your cylinder pressure will be through the roof.
Even the 294 is like a duration of 257 in a 440.
Be sure that you want it that small.
Mine pulls real hard from 2600-5800rpm.
It will do 6800 if I hold the gear, but feels best shifting at around 6000.
I just use ordinary Pump Premium.
I am a bloody hard driver & seem to get away with using all this grunt for accelorating all the time.
That mpg is for around 80-90 mph driving.
I use to go more like 70-130 mph all the time till about 10 years ago; now they would chuck me in jail.([Edited by Moparts - Keep it clean]!)
This is just awesome to drive & I use a Gold Center Force Clutch.
If you are Auto, I would suggest 2800-3000 stall
& go with the tall gears. On the street you will be real happy, & fer the sake of a few 10ths at the drags, you will save [Edited by Moparts - Keep it clean]-loads of gas.
Regards, Mike.

I am aware that the cam keeps the performance down. We had a long think about it. My son wanted a big cam, I wanted to stay alive on the road.
We had 300 HP in a B body before, now we're looking at 500+ HP in an E body with a lot of bite. We decided to go with the little cam for a while.
My engine builder in Belgium planned to build a dyno-room. Due to the recession he decided to not go with that, too bad.
We plan to have the car running in about 18 months, so we still have some time for the final set-up choises. But after this summer we will finish the rear. Because we go on a camper trip to the states, end of june, (east of the rocky mountains), we might take some parts from dollar country to europe!

Thanks guys, for all the effort!
Have one from me!

Ow, and Bigmike500,
I don't understand too much about cams, but I will check your remark about cilinderpressure with the engine builder; They are really experienced mopar-only specialists. Well known on street, strip and tractor-pullers.

This might be my final touch to go with a dyno run on the engine after all!

Thnks.
