More aluminum

Sorry to waste the bandwidth, just getting excited about what this whole project might someday turn into!!!

Dave what is the big difference between your block and the Ta Block.

The history of these blocks as I understand it is, GM Performance made a few blocks (not sure of how many) and these WILL have a casting number on them. However, when the project was abandoned, GM sold the tooling to M&A Casting - Brayton Engineering in Colwater, MI. Aluminum blocks made by them do NOT have any casting numbers at all. These only have the raised power 6 logo.

That being said, these are Stage II, on-center, BMS designs, so.....

They obviously are NOT as strong as the T/A blocks. Mine have billet mains with the center two mains being 4 bolt splayed mains just like their S2 iron counterparts.

Basically, these are exactly like the on-center S2 iron blocks, but with certain areas beefed up a little more because they are aluminum.

You can see that the block oiling system on these is totally different, in that it uses one LARGE central oil gallery running down the center of the lifter bores and the cam and mains are fed vertically.

The T/A blocks are probably going to hold up well even into the 1200 hp range.

These M&A's probably will safely hold up to 700-750hp.

P.S. Anybody got any SII front cover gaskets laying around?? Maybe a new front seal (although this one looks good yet).

Interesting as i understand it only 5-10 of these blocks even exist?

Probably, I've heard maybe 6 or so.

So what is your ultimate goal with this block? 10's? 9's?

It will take all the same parts as a standard Stage II block? How much lighter is it than a Stage or 109 block?

I probably wont be doing a LOT of racing, but I'd like it to run comfortable very low 10's. I plan on running a modestly large turbo and injectors up in the 80's-90's, SII heads, etc. I want a REAL heavy breathing engine so I can get the power without having to cramb a ton of boost at it.

Yes, stage II parts. It is in essence a stage II dry sump block.

The block in the pictures weighs 69.5 lbs. with the billet steel main caps in place.
This block's twin, with the steel sleeves, and main caps in place weighs 85 lbs.

In comparison, my iron 109 block with stock iron caps in place weighs a hefty 127.5 lbs. :eek:
And even though I don't have one to weigh, I suspect an iron SII block would weigh even more than that.

Wow you will have to figure out how to launch it all over again without that 80 or so pounds up front. But you will have to add a cage I suppose which will change things a lot by itself. Running a 200 tranny or a 400? Goes back to the theme of pushing small things hard or big ones easy

Already got the 6 point, which should be good down to my ET levels. Got a good fairly bullet proof 200R4 in it already too. Those two items I got in preps to get safely into the 11's two years ago.
