Some people have NO CLUE! guess hemis are just engine blocks too...... ever look at the difference between a "vortec" block and the first 4.3 block they made..... only differences would be counter balancer and one piece rear mainTruStinger said:no no no. 4.3's pre 1996 are tbi. 1996-on are mpi thats the difference and it is a bigggg difference. the vortec haeds on 1996- are already tuned to the point were performance is the maximum it can go stock while the older ones arent. having heads dont mean a thing. the vortec comes from the engine block itself.
actually, they meant 96, not 94.mxerup876 said:i have a 92 with a w in the vin and my motors the bad ass one with vortec wrote on top the motor. some people have told me that i couldnt have that motor cuase it wasnt used untill 94. i dont really care but felt like posting.
