can anyone tell me what to use. i have either tbi and tpi injection harness nd comps for both. just trying to decide which way to go. what i planned on using is my 358cid. with dart heads(early) with a comp cam 292 solid lifter. i know the engine performs awsome with the carb. but i want to go fuel injection. i already done the modification to the intake to bolt on the heads. has anybody done this or know anyone who has. im not afraid to do the work. but i would like to do it one time.
