Hi so I just installed the trick flow topend kit.I started it up today with the timing set at tdc 0. Car started after some hesitation but ran real rough.just looking for some pointers or advise.
Probably not which means it is going to run like crap until he shells out the $$ for a dyno tune. Always budget in the $600 or so it'll cost for a dyno tune.
Nah, he started it un-tuned most likely which is ok for initial startup but don't expect it to run like stock and not smell pig rich until the dyno guy gets ahold of it and dials it in. Every pushrod build I've done has been like that. Fire it up to make sure it starts and runs and doesn't have any leaks or obvious mechanical issues, shut it back down, trailer it to the tuner, trailer it home and then proceed to break it in for 1k miles and roll.
Yeah you make a valid point, the dump tune is usually the last thing someone thinks of. I will admit when I built my 347 I didn't even consider the amount of tuning that was going to happen. Extra money spent in the right places make a big difference.

Yup, the last HCI I did on a pushrod started pig rich at 260whp at the dyno. 3 pulls later it was at 301whp and perfect AF ratio. I see ppl trying to do idle resets and install "chips" or some other hackjob thing and have to laugh.
