Thank you all, for your comments!!!

I did not fire the engine yet.
My engine is a 388 stroked with forged rotating parts, AFR heads, and i'm planing to run some nitrous. but i don't know if my main caps will survive to this power level! the only upgrade i had made was change the main bolts to ARP studs.
Since i can´t found good machine shops next to me, and main caps drilling are a delicate job, i preffer to not change the original main caps.
I will use this engine just for the street, but, once and while i will spray some nitrous.
How much power the two bolt main caps will handle?
