Thanks. We're not quite done yet. Shawn has a few more tricks up his sleeves - and I don't mean dyno tricks.

thats with a NW 107mm tb with the FAST opened up to 107mm,we also did some internal stuff that i'm not going to talk about

Well done. Remember people - this is a small cam/very mild build. Shawn says there is 75hp difference from their engine dyno to their DJ. (581/539)

Awesome Kevin. My guess of 585/530 wasn't too far off.

Not bad. I picked up approx 64hp and 50Lb/ft of torque in a bullet proof build.

I consider rmyself very fortunate that Shawn pulled himself away from his 1000HP and 2000HP plus builds to build the 427. Somewhere Shawn posted that they "build race engines you can drive on the street". Everything Shawn did on the build was done to the most exactlng tolerances. There's no +/- when he puts together a motor. Shawn and VA Speed still remain a huge secret compared to their HUGE talents.

I have a feeling that in the not to distant future there's going to be a long waiting list for one of Shawn's builds.


BTW: You should see his TT BBC. It's an amazing piece.

Here's the dyno chronology:

427 Old Cam..................................... .......605/588

427 New Cam..................................... ......621/601

427 Port Matched FAST w/ 90mm TB............633/616

427 Shawn Miller massaged FAST/107mm TB..656/614

It looks like Shawn managed to get the FAST to produce 35hp with the FAST. Not too bad,

Are you going to have data from lower than 3k on the chassis dyno?

I love that curve tho- by the time my stall converter locked up you've got 500+rwtq.

That's going to be a BLAST to drive. Shawn has done some excellent work, and I know who I'll be calling when the 427 gets tired and needs a sleeving and warm over.
