G,day,
Did some metallurgical testing of some cranks and blocks, have access to a proper metallurgical engineer to interpret this but he is on leave till early January.
Cheers

Paul this is cool info. I always wondered if there was a difference. I have never sonic ck a block, I just pick one that I know about, or it looks good strong, been lucky so far. Dang 4MB crank is strong as forged it seemed. Wailed on them, never an issue.. TrackBoss CGI will be the tough one on to beat. Still thinking about aluminum one....Hmmmmmm

Aluminum is just weak.....

I know it's an FE block, but the guys at Craft Racing built a 482FE using a cast iron Pond block, then transferred all the guts to a Pond aluminum block. Same exact combination lost 40 hp. Aluminum isn't as rigid and just moves around too much. Loss of power due to loss of ring seal is a big issue.

I agree Brent, but the aluminum that there is loss. But TrackBoss aluminum is strongest bar none, and has a super liner, might loose horse, but not going to be 40, I bet easy 25. We will find out sooner or later. Just think if there was a SHP iron TrackBoss, not CGI, and priced right, they would fly off the shelves.

Brent not sure I believe the aluminum is weak therory!All big inch monster motors are alloy. My best friend just set the worlds fastest n/a 1/8 mile record with 900+ cube alloy block. If the blocks are made correctly they are tough. If they were not i doubt the oem would be headed that direction.

Gday
What i would like is an old fontana block which accepts the clevo gear.
Piece of history and tuff as!

Two identical engines the cast iron will make more power but the alloy is a heap lighter and is able to be repaired easier.
Seen some nasty pics of questionable alloy blocks coming apart, whether that was tuneup or quality
Cheers

Gday Russ,
Yes they did, i did read something about when shelby started making them there were some differences?
Can't remember 100% what that was now, got an idea that maybe it wasnt cleveland friendly where as the old ones were but i could be wrong?
Cheers

My Fontanas are all 9.5 deck. I bought the last (new) one Joe had years ago before he retired and sold off his business in January of 2010. They were sleeved at two different bore ranges, available up to 9.5 deck, and were a proven platform to build power on in WHO Sprint cars. He had several other engines beyond the Ford Clevor; IIRC a half sbc Chevy based midget 4-banger and an Inline 6 Ford head. The V8 block did go to Shelby. My understanding is they only offer(ed) Windsor blocks. Joe only produced Clevors but apparently the tooling had inserts to do either. Besides machining, the only real difference in the castings were the Cleveland oil pan rail widths thus the unique Fontana Windsor style front cover with the Cleveland pan interface. The Clevors were machined for Cleveland mains, cams, and oil pump, but otherwise were Windsor architecture.

Best,
Kelly
