What size shot should i put on my 93 z28 with stock internal with an intake and an exhaust i dont want to worry about anything blowing up

 

the LT1 is fine up to the 100-150hp range, if you have the neccassary supporting accessories.

1) Fuel pump upgrade
2) FPSS
3) WIndow Switch
4) Colder Spark Plugs
5) Ignition retard if your timing is not stock

Please let me know if you have any other questions,
Ray
