Don Terrill’s Speed-Talk

Guys,
I know speedmaster hired one of the Edelbrock engineers a while back. Are their blocks now usable?

Would doing another heat treat require a complete remachining of the block?

Guys,
Inhave come across an aluminum Dart SBF big bore block that has a crack in the #4 main saddle. Looks like it is cracked from the main oil hole and the 3/4” up towards the cam bearing. Is this repairable?
The new use will be n/a, 600hp max.

So what lifters are Cup guys running?

I think I used 74 primary and 80 or 82 secondary if my memory serves me.

Have you run it in the car yet?

I never hear of people having much trouble with any of the name brand rockers on a mild street motor.
Plenty of other things to worry about IMHO...

Did the 418 build listed above ever get dynoed?

I didn't realize there was an ownership change. What happened?

Did these ever make it to production?

The small valve heads will only be beneficial in a full ported effort according to head porter Dave Jack. He claims he can get 340 CFM out of them after tons of work.
The large valve 4V heads would be the winner otherwise.

You can do a better short turn radius I am told. The bowl is smaller I believe.
I have a extra one if anyone needs one.

Did Vizard ever do an article or dyno test?
Will the normal valve notch positions work?

Has anyone done a build with the Profiler 205cc Windsor heads?
They seem like a good deal but I have never seen any results.

Why would you do that? What benefit is there?
