The GM Performance Parts NAL.12480001 LT4 hot came kit for 1993-97 LT1 engines.

How much HP will I gain from this upgrade?

Thanks

 

Most people that I have seen with this kit have been dynoing around 320 at the wheels....I was going to buy that kit and then went with a kit from combination motorsports with a 224/230 setup which have been dynoing around 340 at the wheels with stocke heads.....

So inm my opinion I would go with something bigger, but the hot cam kit would probably put ya around 320 at the wheels with a full exhaust (headers and all)
