Custom harness? I was thinking about a cam swap to give it some noise and would appreciate any suggestions. Not looking to make the most power, just want the aggressive idle sound. I am going to leave the stock iron heads so keep that in consideration. Thanks

I went with a 95 Vette LT1 in my 48 with a 4L60E. I went with a hot rod bracket set up from Street and performance (SP). It is very nice but not cheap. SP also sells an air intake which solves the mass air question. It has a place in the air intake that you plug it into.
I also choose to use a harness from Howell Engine performance.

I think that harness and comptuer flash cost around $800.00.
I decided to leave my motor stock for a few reasons.
1- Mine is rated at 300 hp stock. But your motor I believe would be closer to 265 hp, so I can see your point.
2 - I don't like to take the dependibility away by making changes to the motor.
3 - it only has approximatly 15,000 miles on it.
I also sent a new gas tank to Rock Valley and they addapted it with an in tank hi volume fuel pump. I didn't like the idea of a fuel pump outside of the tank.
Besides some sticking injectors, I had no problem firing the motor. This was the first motor swap with EFI that I had ever tried.
Good luck
