[DeTomaso] For those who like engine builds

[Kirby Schrader]

Tony,

It was not dyno’d, much to many’s disgust and disappointment.
Honestly, I spent so damned much on the engine, I was loathe to spend more knowing what I already knew from Tom.
I don’t know if you’ve ever tried to put a dry sump motor on a dyno, but it is a much bigger chore than one thinks, unless the shop is set up for that already… The one we used is/was not.
So, I passed on the dyno.

My motor has just slightly more stroke and just slightly less bore than Tom’s engine, which dyno'd at just over 705HP.
He spent a lot of time and money tweaking intakes and stuff with his, so I was pretty confident mine would do the same.
Or maybe better?  :-)
Bore =  4.133”  Stroke = 3.30"
They are both 354ci

The only differences between the two motors:

 - The cam is identical except for a little more lobe separation for the Webers.
 - The well aged and tweaked Mike Trusty Webers, of course. Tom uses a worked over Holley.
 - Tom uses custom ‘zoomie’ headers with Borla mufflers that look like 180’s, but they are not. I use good old GTS headers that have been whacked off and a 3” collector welded on, then 3” tailpipes with some shortie Magnaflows.

I was hitting the rev limiter at 8000rpm in 4th at the end of the TWS straight, so we moved it up to 8200.
Tom’s got his set to 8800rpm. Neither of us use 5th gear.

Prior to running into the Javelin at the last CVAR event, I managed my first 2 minute lap.
Getting there, slowly but surely.

Regards,
Kirby
