I don't want to open the motor or do heads. Prefer not to do LTH, if can get away with it.

Will a setup consisting of:

2650 Maggie
JMS BAP
LPE BB or Goliath
+30% injectors

hit close to that target?

Is a transmission tune necessary at that power level?

I know Kong X-porting the LT4 can provide nice HP gains at the expense of more heat (I don't want meth). Might kill my road course race days.

Was looking at the Whipple 3.0L but having to shim the subframe and cut the hood insert aren't preferable for the ZLE.

Perhaps later, when that HP level isn't working anymore, I can always cam, LTH and put a higher volume LPFP in, or add the upcoming DSX PI setup.

Yes that will get you in that range and I’d certainly recommend you run some E. You don’t need full E85 to get most of the benefits… I run E50 to run my numbers.

TCM tune is not necessary, but the car is slower without the tune.
