Mopar 440 to 493 cui stroker, how much power?
 

Hi! I have built a Mopar 493 cui stroker with succes, i brake in the camshaft (Comp cam xe275hl) in Juli for 25 minutes around 2000 rpm, the engine fires right up and it all went well. I brake it in with Joe Gibbs assembly grease on it and Joe Gibbs 10w-30 brake in oil in the engine. I change oil after that and cut the filter open and no metal in it. I have drive the engine around 400 miles now without any trouble so i belive i now can say i have make it with this build. I have also change oil and filter a few times under this 400 miles and cut the filter open every time and find nothing, it runs great. I have not run the engine in any bench so i dont know how much power it put out. The set up is: Mopar 493 cui stroker, 4,150" Eagle crank, 6,760" Eagle H rod, Mahle forged flat top piston, Mahle file fit piston rings, 10,45:1 compression ratio, Comp cam xe275hl(231/237@050) camshaft, Edelbrock e-street 84cc cylinder heads, Prw 1:50 stainless steel roller rockers, 3/8" push rods, Comp cam 822-16 hydraulic lifters,Edelbrock rpm intake manifold, Edelbrock avs2 800 cfm carburator, Mopar HP exhaust manifold to 3" exhaust pipes, FBO blueprinted distributor with vacuum advance and MSD 6al box. Drive line: TCI streetfighter 727 automatic gearbox with TCI break away converter 2400 rpm stall, 8 3/4 rare axle 3:55 gear and a helical Eaton true trac diff brake. I know the cam shaft is pretty mild for the engine but i want it that way, i want it to work best on the street, im courious what power i can expect from this engine set up? Can i expect atleast 500 hp or what do you think?

You should be pretty close at the flywheel.
You'll have to dyno it or get some track times to confirm.

Ok, thanks for the answer. Its really not that important to know, im just courious and it would be fun to know but im happy with how much more fun the engine have be from how it was before the rebuild, a 1977 440(smog). It has tremendous low end power, the top end i have not really try out yet, i want the engine broken in properly first, i can say the car not really feels like a heavy c- body any more, the engine really makes the car moving now

i bet! that is one heck of a v8. :D

also, if everything is working properly i bet it's putting more than 500 horse down. substantially more.

Thanks:) , yes its one heck of a engine and its running great. I have been extremly regorosly when i build this engine and has not left anything to chance when i building it. I have not drive it really hard yet, i have 400 easy miles on it so far but i have try to put in second gear from stand still and give it about half throttle and i spin the tires loose and the 4 400 pound car goes off like a bullet from a gun so it is no doubt there is power in it:)

After you get to the 1000 mile mark.... Take to your local "Chassis Dyno" shop and have then run it and tune it.... Then you will have most of the right numbers and a good tune.... :)

Yes thats probably true👍👍

Should be good to go now! If you don't have the rings seated by now they never will be.

Only reason I choose 1000 mile.... I like to lose a little new build friction out of the engine.... Just my 2 cents....

They are seated, i have 185 psi in all cylinders and the spark plugs looks great, the engine runnings really great it just feels comfortable to take it esay in the beginning of its life😊

Thats how i feel to👍👍
