IF YOU GOT A 96-98 GT THAN YOU NEED TO GET A HEAD SWAP CAUSE THE 99+ MODLES HAVE DIFFERENT HEADS THATS WHY THEY GO FASTER. TOTAL HEAD SWAP WILL COAST ABOUT $1500 BUT WILL GIVE YOU 45HP DYNOPROVEN.

 

1500.00 for 45 hp..it's not worth in..hell pull the heads and have them reworked for about 500.00 bigger valve and some port work..you couldn't give me a 99 4.6 gotta love that 1000.00 intake...<edited><editID>vfast</editID><editDate>38008.8667939815</editDate></edited>

 

Is there a point to this thread? I think most people here are aware of the difference in '99+ heads. By the way you can get fully ported heads and intake for $1,500 or less if you look around, and you can easily pick up 60-80 horses, which is totally worth it.
