Work on the car has has slowed down. My family is outgrowing our living situation and we are planning to move this coming summer God willing.

One of our must have's is going to be a decent size garage. Until then I'm doing a lot more selling than buying online to speed up the process of getting a new home. My car is outside under a car cover at the moment and it is such a drag to work on it. Moving the tools, welder, etc in and out alone takes up too much time so I've just decided to stop for now.

But some progress has been made.

When my engine builder degree'd the cam the specs were way off (they sent the wrong one) so that started a cascade of changes to the build.

I called Chris Straub and now I have a new cam on the way:

Cam Specs:
BBC Gen6 Stepped face Fit Camshaft (No cam shimming needed)
Adv. 288/300
.050" 229/241
Lift 600/570 with 1.7
109 Lobe Sep

Chris said I should be shifting around 6700 - 6900 rpm (Fun!)

Thus,
I also decided to run 4.33 gears since I will have more rpm's to play.

With a 2.20 first gear and 26" Tire, my SLR is about 9.5

If I decide to run my HONE overdrive the 4.33 becomes 3.031 and I can still cruise on the freeway around 2500rpm.

Brakes:
I'm running original '69 front disc brakes since that's what we would have pulled from the wrecking yard and I'm going to sell my '67 brake brackets and calipers.

Intake: Good News
Chris Straub recommended that if I wanted to stay all GM to run a 198 intake. I sold my 198 intake but I will just run a 163 and cut out the divider. With this setup he says I should get an easy "500/500" and still be able to run 91 octane and full timing.

Flat Hood: Good News!
And I've confirmed that a 163 using a GM air cleaner etc WILL fit under a flat hood. The "Low" spot is the bracing near the front of the air cleaner. The bracing is in the same location for an SS hood as a flat hood. It will be snug but I'm glad I won't lose the HP using a 569 intake. The key is using the right engine mounts that will not put the engine too high. I may mill the top of the intake just a tad for insurance.
