hey everyone how is going?This is my first time trying to build an engine.I know a guy who has been building sbc's for a good while, and bought some parts;a crower billet steel crank (3.250 stroke) carillo 5.7 inch rods and je forged aluminum pistons with a 12 cc dome and air flow research 195 heads with 74 cc chambers.The block i got is from a 350 goodwrench engine.He said that this will work , but some one else told me that 327's need 6 inch rods or 6.125. Is that true?And how much power will a factory block handle before is breaks?I also plan to put a shot of nitrous, about a 150 or 200 shot to help ad some torque.Any help would be appreciated.
