Well i suppose that most of you have head of my meltdown and subsequent emergency brain surgery. It has taken 3 months out of my life and the prediction is it will take 9 to 12 months to recvover to a best of 95% on the right lobe of the brain.

Needless to say this has had a devastating impact on my REC build wich was a really high tech ddeal with a lot of custom parts. Wel that won't be finished by the date so I have had to change course somewhat.

There is an engine which Terry Walters and I are going to substitute in the competition. There is still quite a lot of work to do to this substitute but no where near what our originally planned entry.

Here is the new game plan. We are going to build a right off the drawing board 427 SBC. No screwing around testing multiple parts(especially cams) - the build will be exactly what my TorqueMaster cam program says it should be. I want to show the TorqueMaster can edow the novice with the info to build a really high torque/hp motor first time around.

There was a 427 -23 degree SBC that I showed the power curve for a few months ago. If I remember correctly that made - on 87 octane fuel - 1.41 lbs-ft per cube and pumped out over 700 hp- not bad for a true street driver. Build spec - 100% TorqueMaster.

Go back about a couple of years and there was a bored and stroked 454 which went to 505 cubes. This was another 100% TorqueMaster specced build - 1.43 lbs-ft per cube and aver 800 hp - on 87 octane fuel.

I may not win the competition but I am sure I will win over the confidence of a few open minded engine builders who will see the benefits of a motor build using all easy to get 'off the shelf' parts and get the near perfect combo and have the build done with the least shop time involved.

Almost the same as last year ... thicker head gaskets, very slightly different cam and bigger carbs is all.

David if you added 2-4 degrees and 92 octane on those last 2 motors what would have been the outcome? :)

Fitting this 23 degree tunnel ram on an 18 degree small block Chevy is becoming a real bear.
If I knew anything about mechanical fuel injection it sure would have been much easier to have used the sprint-car stuff that was on it.

Oh well ... live and learn.

Converting the dry-sump engine to an internal wet sump was easier than I thought, though.

Not this year but, only at wide open throttle when I did test them against one another in past years.

Here the EFI was down on tq through the whole range,, it did catch up as the peak hp was the same.

Pretty difficult for it to cool the intake prior to a pull like a carb...once the intake is heat soaked on the EFI, it's game over on comparing it
