OK, so the 88 GT is in the shop getting some needed maintenance. After it comes out (tomorrow hopefully) the Grand Prix GXP goes in for maintenance.
I have been researching my butt off on the Cadillac HT engine separating facts from myth and developing ideas for what I want and how to get there.
For one thing I am now certain that both the 4500 and the 4.9 are very good engines (much better than the early 4.1s)_ and most of what I know about hot rodding can be applied.
I have sorted out some of what can be mixed and matched, and some of what cannot!!! This has opened up new power options.
For now, the 4500 stays in it with the 450 cfm Holley. It is getting a mild nitrous kit though. I also have a manifold being ported and polished to be installed down the line a bit.
Down the road a bit further I intend to build a high compression 4.9 and have already ordered heads and manifold for that.
I only expect to make a little over 225 WHP (300 with the nitrous) with the 4500, approaching 1 hp per CI. I expect to make a little more than 1 hp per CI with the 4.9 and even more with the nitrous!
If that setup isn't powerful enough, then its time for a turbo!!!!!!!!!
Call me CrAzY if you must, but wish me luck if you can....
