my last set up (now on my garage floor) was 455 with RAIV cam. D Port, 2.11 / 1.77, 9.5 to 1, headers, etc..... Based on my experience, that cam really shines in the window it should be run within.

For automatic, this is what I recommend (what I ran):

Full built T400 (aka very hard shift) with 2600-2800 stall.
9.5 to 1 preferred over 8.5
Big Valves both sides
NO Air Conditioning
3.55 gears ideal. (4.11 are carnival ride, I tried.....)
This cam begs for header type flow to run its potential... this kind of engine gets 40-50 hp with quality headers on top of rest done right.....



What you have with a well built 455 RAIV is a very cold blooded initially, marginally streetable, full romp machine. if fun is desired result, it does work. The car vibrates at a stop sign idling, the side windows shake blurring vision, and it either sits there or snaps when you gas it and it launches, which basically is mostly what you are tempted to do, is Launch...... that is what that cam is designed for really....

so it is all what you are trying to do with the car...

this same engine when I put in the white bird eventually will be de-cammed a notch and no high stall set up, more a stock tranny set up. Totally different goals now..... (Cruise vs Max)
