People ask how much HP my new 390 have and i say i realy dont know.
What do you dyno guys think
390 +.060 0 decked 10.5/1 ratio,flat top pistons, stock crank,rods, C4 G heads with a "streetport job" mostly
worked on shortside radius, CJ Valves,Ported Streetmaster, 800 DP Comp 282S ,shorty castiron headers
Duraspark with MSD 6 AL.
What HP and torque when working like it should. My guess just under 400/400
what would i gain with say a 294S cam like i ordered but i got a 282s
-
I'll let the dyno guys/engine builders make the educated hp guesses, but I will say this: That sounds like a great combination as long as you have enough octane to run an aggressive ignition curve.

I would be disappointed if that combination wasn't well into the 400's.

I dynoed a similar 390 combo a couple years back with a smaller cam, made 400 HP and 445 lb-ft. My guess on yours would be 415 HP, 455 lb-ft. I wouldn't go up to the 294S cam, that 282S is a really good match for your combination, in my opinion...

So 400+ hp and 400 ++tq you guys say. And no cam change
Would i gain anything with a performer rpm? I'm thinking heavy car and dualplane intake
I definitely need a better exhaust just a dual 2inch i installed two Mercedes Diesel mufflers
on to pass tec inspection. but its ooo sooo quiet ;D
Thinking about a AOD trans cutting of the bellhousing and machine a C.O.M bellhousing to fit
must be possible or just reinstall the stock T10
and build a AOD for the stroker engine
-
At that power level I think you would see little or no improvement with the Performer RPM.

I was thinking maybe low rpm part throttle. borrowed your book
to the headguy, so i dont remember what the comparo tells
