what size wet shot should i run that would be safe on the stock rods and crank?anybody w/similar mods let me know your times.

That depends on what system you are using. I only run foggers i would put in a 350 hp tune up but then i like pushing the limits.

 

basic nx wet kit,i think a 350 shot would be a bit to much.

 

I would be afraid of a 200 shot if i had your motor. People use that much with stock lt1's. Start with a 150 and work you way up.

 

Sorry guys i only use NOS, it is the only thing i trust. I know how to tune it right. I have never blown up a motor I didn't want to blow up, for the hell of blowing it up. As for NX, ZEX or any other company other then NOS I am sorry i can't help you. I don't know enough about them i have used them yet and I probably will never use them. If you are dealing with NOS and you need help give me a shout and i will try and help you out.

 

TNT or NX, i would start at 100 and work up since no forged crank

 

I'm pretty conservative, I'd say 100hp, maybe 125. I like the NX wet kit, but as with any kit you also should have a bottle heater, pressure gauge, and a window switch for safe, efficient operation.

i'd say 100-150 starting,and i like NX setup's for these cars.

 

I also use NX. I started with a 75 shot and went to 100 then 150. I started low to get a base tune and go from there. On the 150 shot i am still a bit on the rich side at 11.8:1 I am also still running stock timing with no retard but a mix of 93 and 110 octain.Most everyone i know uses NX on their fbody with no problems. To answer your question start low and go up. If you can i would do it on a dyno with wide band.
