14044807...454T..............4-bolt, Bowtie, MkIV, CNC prep, Tall deck, 4.25" bore or 4.495" bores

Pistons should be dish aluminum.

Pro Series crankshaft
Stroke: 5.300 in.
Main Bearing: 2.750 in.
Rod Journals: 2.200 in.
Minimum Rod Length: 7.200 in.
Rear Main Seal: 2-piece
Nice crank, about 2G's

If that is the crank that is in that engine it night be a good one, but hly hell that is a long stroke to be putting in that block.

I would never go bigger than 4 3/8 and that is pushing it

Go back down to a 4.25 crank and a flat top piston. You'll have much better results over all.

No wonder it came apart.

if the block is not split it can be fixed

Thats what i was thinking.

Also a Bowtie talldeck is better then the dart or merlin blocks !

I just like them .

No it's not. They are old technology. Good blocks, but not as good as a modern DART

Thanks for your help guys I am still having some trouble with the cam though the numbers on it are CR13H000036, 200486, 13-18-00 and here is a link to the lunati web site for my crank what is the stroke is it 4.375 or 5.300 again thanks for all the help

If it really was a 454, then it is a 4". If it is any of those others, then it is a bigger engine than 454

4.25 crank would have made it a 496+- depending on the overbore.

Anything bigger than that is worthless in that engine IMO.

Take the whole pile of iron to a machine shop down there. OWENS is probably the better one down there and let him TELL you what you have and make a decision on wether to mess with putting it back together based on real info and not speculation off of this board. He is up in Pearland. There isn't any other shops down there that I would trust with anything.

He will shoot you straight. If you need parts, I got a whole shop full of them. I got some engines down there right now also if yo uwant to look at some of them. He is running them on his dyno.

Find out what parts you have from him and I might take what is still good in on trade from you.

Jeff,,,i call BS on that.
My engine is a standard deck Bowtie 454/509, with 4 " crank and 4.500 bore.
And still have room to go .90 over !!! easy.
U can easy build a 572 out of mine so a 620 out of a bowtie talldeck would be no problem.
The bowtie's are siamese bored blocks ,,i think the new ones are not ?!
The biggest crank i ever seen in a bowtie talldeck was 5.25 " stroke. Still running.

mmmmhhhhh.........................
I say fix the block and go with an engine builder that knows what he is doing.

572 out of a standerd deck block?
