350 block, 4 bolt mains, new nodular iron GM crank, new GM powdered metal rods (LT1 rods), 4 valve relief dished hyp. pistons. What kind of shot would you guys run on this motor with a good tune? Its my 350HO crate engine. Currently I run anywhere from 12.6's to 12.7's at 107-108.9 mph. I will be ordering the nitrous express hitman kit very soon with a dedicated fuel system for the fuel solenoid.
A little more info on the setup:
MSD 6A ignition, MSD Pro Billet Distributor, MSD Blaster 2 coil, Edelbrock Super Victor single plane intake for vortec heads, Demon 650 mech secondary carb, ported/polished vortec heads and an XE274 cam (110 LSA). The motor is fed by a 110 GPH holley Strip mechanical fuel pump, the fuel solenoid will be fed by a 1 gallon Jaz nitrous enrichment fuel cell and a holley blue fuel pump.
Anyway, how big a shot would you guys run and what kind of ET/MPH difference will I see?


Thanks guys,

Seth

 

I would stick to a 200 shot or less a friend of mine has had durability problems with the powdered rods , seems they dont hold up to shots over 250 HP he broke two, in to three and five pieces on a 250 shot destroying his block and heads we still dont know the exact cause but just a heads up it was also a 350 crate and only had thirty runs on it 20 without N20!

 

Wow, I wasnt thinking anything near a 250 shot. You realize these rods are only "rated" to 425 horsepower

 

UHH .. ya I realize they might not have been up to it .. unfortunately my friend dident share the info when he got the engine .. but we tend to nitrous the snot outa our engines anyway... go or blow !!!
