I have always heard that a stock engine could take a 150 hp shot of nitrous. I ran my magnum motor at this level for 3 years before I build my 408.

i had a stock 360 bottom end with forged repl pistons, Stock crank stock rods etc, In my car it ran 13.00 on motor and 10.90 with nitrous, It had two plates stacked for a two stage, both jetted at 175each so yea that was 350hp on a stock crank stock rod motor. Keep it out of detonation youll be surprised at what lives..Id keep it to 175 though and you should be ok. A 360 cast crank is pretty beefy
....BAD A$$ STREET CAR.....

.068 around 200hp .078 around 275hp
most stock engines can take a 150 shot with no problems, as long as you take timing out and run good fuel, might have to put a colder plug in. just keep reading the plugs.

blk00rt did your magnum motor have hyperutectic pistons when you were spraying N.O.S. on it.If it did,were the rings gapped bigger for it.I have a 360/380hp crate motor and I was wanting to try spraying it without regapping the rings.Maybe 100 or 125.I only run 1/8 mile.

the 360 magnum was a completly stock lower end. It had hyper pistons and rings were never touched. I ran it for 2-3 years on the stock bottom block until I decided to change to the 408.

There's a number of guys on the Dakota R/T Forums spraying 150 on stock bottom ends, and have been for years...

"Thanks for the info.Did you say you sprayed 150 on it?" yes, I do have a timing retard unit and I pull 1-2 degrees out but I dont really have to, I do it just to be safe.
