Ya it has H beam rods What would timing be set at with a 200 shot and what jets should be in the carb with that im new to the carburated stuff i Think the car was prob a 10.50 .60 car as it set it just didn't have a big enough converter and i also think it wanted a bigger cam it ran a 10.9 in 85 degree weather i couldn't imagine a 200 shot of nitrous

i'am running 22 total timing, mines locked out 22' all the time, exc. for start up , i got a msd dig 6 box. i got a 1000 demon carb on a 408 with victor jr heads, cam is s/roller with 264/276 at .050 lift is .701/.689 i got mine to run 10.0s at a buck 38.
if you got 6.250 rods you got a thicker top land on your pistion than the 6.200 rod ,which is what i got .i would still go 250 with timing set to 20. just run c -16 gas straight. i got 11.7to1 also. i haven't run mine in a year.

your ok at 10.5 to1 but with the nitrous i'd run some c 16 if you dont have cats. or get a separate tank,and pumpsfor the nos system.keep c 16 in it , as for timing 35 is good for all motor , but not with the nitrous you will hurt your motor with that much timing. im running 22 with 200 shot.what type dist you got ? i only run mine once every year or so. i got the msd dig. 6 box that retards youre timing when youre spraying it.

its got to be a msddigital 6 box
as for turbo you got to much compression
id be happy running what youre running right now.
nitrous can hurt your motor , if youre not careful, alway got to be on top of the timing temp outside and bottle pressure,
i hurt many of motors to know what to do and what not to do. i never hurt a motor without nitrous.
things like bent rods.
i got a 94 351w block, with no girdle either running 10.09s 6 times back to back runs. 6 run burnt the clutch disc up.

Chris,i suggest you just get a little 4 banger import because you wouldnt be able to handle that car with nitrous

How much is that 6 box the reason i had said turbo is because i haven't got my pistons so i may get lower compression ones but i know nitrous is cheaper i have the cheater nitrous kit already with 150 through a 250 shot. Id love to have the turbo power always there I just like to get my car down to around 10.50 on motor which i think is very possible what you think i should do so many options....
