--------------------------------------------------------------------------------

I have finally put together a little web page about the Block Summit which was held at Wes Littrel's place almost 1 year ago. On that day 30 odd blocks were sonic checked, weighed and recorded. I've scanned all of the data sheets from that day and included them in a .zip archive which can be downloaded and viewed. The pages are in .tif format so they are not real huge and the quality is pretty good. Enjoy.

Here is a link to the page:

The time and work to sonic check all those blocks and put the data into a useable table is greatly appreciated. Thank you.

John.

I know that took quite awhile to put together for all to see; thank you.

Dave, please put this Block Summit link into the engine build forum.

What needs to happen now is to have someone who's good at that sort of thing, take the data and place it into a spread sheet of some kind and find the averages, best and worst block etc. That would be very interesting.


I also placed a link into the engine build part of the forum.

I have been looking at the data, and thinking of putting it in a spreadsheet. I do have a question about the data sheets though. I noticed that some of the measurements have 2 numbers (example .163/.210) please explain this to me, as I am trying to figure out what number to use, one or both, and if both, then were the 2 numbers taken at different points. Also, what results do you want to see?

You tell me what you would like to see, and I'll see if I can create it in excel. If not excel, then I will put in into an access database and create a little program for you to use.

64.251.141.232 Data Sheet numbers
No score for this post January 10 2006, 9:04 PM

The data sheets were not drawn out exactly correct for the block summit. I took readings in 4 postions around each cylinder at 3 different depths not 2 like was on the worksheet. The readings were taken at 1 inch down from the deck, 2 inches and then 4 inches. The first number is the 1 inch down reading. Then the 2nd number(number after the slash) is the 2 inch down reading and then finally the 4 inch down reading is on a line all by itself.

The positions around the cylinders and the cylinder numbering are correct.

The Block Summit was a very long day for me and everyone because there was a lot of work to be done. It was also fun because everyone worked together to make the event happen. We had some great food let me tell you and that always goes a long way toward making any event sucessful. Charlie and Jay's informative talks on heads and castings in general were excellent and I think everyone came away with some newfound knowlege.

You did much of the Heavy lifting that day Dave so you were probably as tired as I was when we were finished. I sure had a great time and I really think that we should try to have some other summit one of these days, maybe heads?

64.251.142.143 Head Summit
No score for this post January 10 2006, 9:43 AM

A cylinder head summit would be cool but when I discussed it with Charlie we were at a loss as to how we would do it exactly. Flowbench tests would be great but the whole thing would have to be done very carefully so that it doesn't turn into "my heads flow more than that" etc. Velocity mapping, port volumes etc would also have to be compared along with testing on various bore diameters. At the same time it would be extremely cool because of the plethora of cylinder heads which are now on the market for this engine each with it's own special features and application that it is best suited. It would be great fun to figure out a good pecking order for the heads, D3's, DOVE's, Edelbrocks,TFS streets, DOOE-R, A-429, Blue ThunderA,B SCJ A-460,EX-514,IDT,C-460,Thor etc. How much bore size and cid they each need to work best would give our group a lot more knowlege.

Did some blocks have a cleaner looking casting that others?

I have a DIF block in my boat that looks very clean and no casting flash.

My Motorsport A-460 looks like crap E8 casting number.

Great info thanks men.

No score for this post January 10 2006, 9:06 PM

Some of the blocks did seem to have somewhat better casting quality with less sand and stuff like that, sharper lines and smoother finishes but again, there seemed to be no real patterns to any of that. Some of the D1VE's for instance were rough, some were very nice.

Thanks to Byron all the data sheets are now easier to access from the Block Summit page. I put a link on there to the page that he designed, looks nice.

Also don't forget to notice that block number 32 is actually a big block Chevy that I sonic tested for a customer here at our shop. It's a .100 over 454 block and I thought I'd include it just for comparing the cylinder wall thicknesses remembering that a +.100 big Chevy is still a .010 smaller bore size than a stock 429 or 460.
