Re: Piston rings

"Any increase in the diameter of the cylinder is being used in, over the designated size, results in an increase of approximately .003″ in ring gap for each .001″ increase in cylinder diameter" The opposite is also true. The "issue" isn't tension...and your tension in this instance will increase, no...

For fords....or LS...since their the same engine...there is always Greg Brown's Hammerhead Hemi conversion. 927 NA hp from a 427ci Ford.....and I've heard a couple of guys have done over 1,000 na.

Hey pdq Have you ever considered it would be easier to put a newer drivetrain in something. You know motor and trans mounts Than to Frankenstein an old junk pinchport pooch thats neutered by a 3" stroke? Have you ever seen an LS7? In person?

Re: Why no Ardun hemi head SBC conversion?

The story I heard, was that at the start of WW2, some of our smaller tanks were built with the flathead Ford V8, and that more power was needed because of the weight of the tank. The Ardun heads evidently took care of that problem. Ford built a 1,000ci hemi engine for tanks in WWII. Here's one in a...

Re: Piston skirt differences regarding pin height

The crank grinders seem to do the counterweight for the rod length and about .200 under the pin. The majority of pistons have about .150 under the pin.

As long as you don't change your rod length and run a Top Fuel piston, you should be fine.

Re: SBC HFT lifters best buy ?

Most everyone is out of chevy hydr flat tappet lifters. We use the 817 lifter, and they are back-ordered The plant in Michigan, that makes them has been closed for months, and just opened back up, about a week ago. They're producing lifters, and filling back-orders as fast as they can, but it'll pr...

Re: What is the quality of the current Chinese imports?

Econ 101 tells us that price is king. It certainly has an impact on my purchasing decisions. But not all of them. There's the performance side of things. I think that's what the original intent of this thread I hijacked was directed towards. Then there's also the patriotic aspect. It is patriotic t...

Re: Speed pro power forged piston clearance .001!!!

The skirt clearance, is based on the aluminum alloy and not if they are forged or cast. My Speed Pro catalog, calls for .0015 clearance, for that piston. Skirt clearance is based on skirt profile, gauge point and application. Are you trying to say that the expansion rate of the type of aluminum all...
