[quote=Deathstar;231259]Ported and shaved Heads + Crane 12's are installed on the car now. We shaved them .020, bringing the compression up a full point we think. I believe I can feel the difference in the seat of my pants, but want to get it to the dyno first. The new lake pipes are LOUD! I am dumping the header into a Thrush glasspack then splitting it out the sides in front of each rear tire. For a NA, it is starting to get pretty mean. More pics of the car to come soon.

As I stated before your project has become the spring board for my own. So with that (since you've been so helpful already) I have a few specific questions/concerns about my own project NA PT. -
I'm looking to do the following to have some more fun with my PT(hopefully adding about 20+ HP and at 20+ ft lbs of torque in the process):
- get my head ported (about 1/16” removed to match intake runners) and decked .010~.020” to raise compression ratio from 9.5 to 10~10.5 (don't want to go higher than 93 octane for daily driver)
- Install #10 crane cams for increased horsepower, torque and throttle response(don't plan to race often just want more power than stock without too much mileage penalty).
Crane #10 Cam-
Part Number: 193-0010
Grind Number CHR-242-10
Advertised Duration Intake/Exhaust 242 / 242
Duration @ .050 Intake/Exhaust 200/200
Lobe Separation 110
Gross Lift 354/354
Stock Cam -
Part Number: Stock Cam Specs BACK TO LIST
Advertised Duration Intake/Exhaust 248/248
Duration @ .050 Intake/Exhaust 194/196
Lobe Separation 113
Gross Lift 325/259
Will my stock CAM gears work with this cam? (I’m hoping so since the duration is only 6 degrees longer than stock) I shouldn’t need adjustable cam gears right?
Crane clams “good idle quality” with this cam, but is that “good” for a cammed up motor or good compared to stock? Any experience with this?
Will this cam raise my redline or is that determined by the computer?
Will the stock rings hold up against the increased compression? Or should I expect increased oil consumption?
Will my PT computer and injectors be able to maintain the proper A/F ratio? (the cams not that wild so I’m hoping so, since you're already running a #12 crane cam with stock PT injectors/computer)
Will the engine require some level of “tuning” to run well, or will the computer be able to make the adjustments on it’s own?
Thanks guys I’d love to hear your feedback/opinions!
Tom
