How big of a motor can you make out of a 670 block 800 heads

How big is directly related to the depth of your pockets. 900 cid is pretty big. Jeff

I am gathering parts for a 5.50" bore X 7.625" stroke, Jeff G. Is putting the 800 jugs on a 670 crank case for me. Real good guy to talk to.
I would say this is an average build... Some smaller and some a lot bigger!!

Jeff what's the bore and stroke for 900. Can you build one 1000. Looking to beat up on some 460 with red diamond motors.

MM heads will not flow enough to feed a 900 cid 4 cylinder motor. 1000 cid is a total waste of money unlees your main goal is to brag on how big your motor is.

If you are looking for a crank, I have one 7.625" I have not decided if I am gonna use it or not.... I might stay at 7.00-7.25...

It was welded by Jeff @ Stamm Equipment, and never used. Now for the bad news... It will need to be re ground as it was set up for U rods which will not work!!! Would have to do a custom rod... Give me an email address if interested, can send some pics too... This crank cost $2500 originally!

6.125 by 7.75 makes 913 cid. 800 parts are the only possible way to make that combo work. I have been itching to make one of these and if you got the money, I've got the time. Even with these inefficient old bastards taking around three cubes to make a horsepower that is still a pretty good ride. Past that a person needs to be building a LSS or LLSS.

$2500 for that crank? Sounds like you got screwed.
I had one welded up and turned for about half that much.

MMU where can you get a crank stroked 1.625" for $1200? Is it still together?
Is it a backyard weld job? Bobby Hinton told me about a hack shop that are just welding blocks on to the journals and grinding them down and out the door they go! They do not last long

I did not have this crank done... It was another puller that had it done never put it together and lost interest, his loss my gain!!

I do know that around my area, guys are getting over $100 for every 0.100" of stroke added, 1 shop will not even quote it, it is a flat rate $80 until it is done...
