well since im pulling the motor in my truck to put a 5 speed in i decided to upgrade the motor a little bit and was wanting input on bolt on mods,pistons and cam stuff like that id bore it out but dont have that much extra cash to play with but but i have a little bit extra to mildly build my motor

 

sct tuner from hemifever , make sure it geared for towing ?

 

SCT tuner as mentioned above.

50mm throttle body.

Kegger mod. (easily done when you fix the plenum.....)

Headers, and free flowing exhaust.

Harland Sharp 1.7 Roller Rockers.

That'll wake it up nicely.

 

Harland Sharp 1.7 Roller Rockers!!!!

And a 5-speed.

 

i found a 52.5 mm tb used for 250 would i have to upgrade injectors or anything?

 

That is a rip off. And no, you wouldnt need new injectors.

 

ok well whats the biggest cam i can get without doing any major changes and whats the best pistons to buy since the stock ones are low compression?

 

Depends on what ya wanna do, what compression you want, what fuel you want to run, and just exactly what performance you want from the motor.

 

why dont you do a .30 over bore and shave the kegger and trim you heads slightly, and if you want top end, port and polish.

 

I would replace the heads, rather than shave the already too-thin deck thinner......
