301 increased cubic displacment

I see so many topics on this mostly in relationship to big bore kits with sleeves and custom ross pistons etc. So why not stroke the crankshaft to lets say to 5.00 stroke. Then mill off the deck the stock piston for compression height of oh lets say .010 below the deck, and clearance the skirts to crankshaft and of course mill in the valve reliefs ? 353 ci.  what I am getting here in this topic is I read awhile back there was advice to do this to a 426 and use stock rods harden then clearance the stock piston . supposed to be cost effective cause you will not have all the machining expenses in custom sleeves and pistons etc. according to the post.  I have not measured out all the specs like crank to cam and crank to oil pan deck. maybe the reason ! Or do the bowls get to shallow and cause the compression ratio to go crazy high ?   thoughts ?

Hi DR Allis ,   well that's what I was wondering on clearance issues at the block and crank to cam etc. so in the other fellers post on 426/466 there must more significant room in the block and adjacent area's than a 301?

crank to cam clearance is a mild issue on the 426 at 5.5". I could imagine the nightmare clearancing that 5" swing in a 301. Rods with a smaller big end would help. When we cut the top of piston down, we cut the whole top down, including the bowl. 

A 301 can be stroked from a 4.250 to 4.500 stroke with stock rods. Some clearance issues with the camshaft, but a little grinding and you are OK. I have researched this a little and with a custom set of offset rods you could possibly go to a 4.650 stroke maybe 4.700.If you went that far I would guess the strength of the crank would be compromised if it were to be used for a high HP application. So, with a 4.7 inch stroke (if possible) and stock pistons in a 301 you go from 301 to 332 cubes. Wow, that's a lot of work and money spent for 31 cubic inches. You can get to 341 cubes without even boring the block by using high strength sleeves and pistons that fit. You can bore the block and get to 383 C.I. easily and still use the stock crank.

There is a lot more room in a 426 for a stroker vs. the 301. That's why it makes sense to stroke a 426, but doesn't with a 301.

That's what I was wondering why others haven't done the same as the 426/466 post . Correct I would not do that for 31 cubes . Rather add a second turbo and let it rip that way..

I had fixed up some aluminum Indy heads for another engine a couple years ago.  I bored the injector hole out and threaded the bottom with a 1/2" pipe plug. 

They make some pipe plugs that are machined with 14mm spark plug threads and seat in them to repair old heads and this is what I used rather than trying to thread into the aluminum.  I was moving the hole offset to center it in the chamber better and just didn't have room to run the smaller 14mm thread.

Dr.allis I have that 441 motor and it's for sale if you know of anybody.I can be reached at716-866-2114.it's apart and ready for reassembly, priced very reasonable.

Sorry I missed your calls Billy, PM me.

hi new to forum. I am wanting to pull this year with our new club. the class is 6500 or 7000 lb no turbo farm and field class. what I need to know is what I can do to my 180 d . how much can I get out of her with the pump and injectors, any suggestions thanks.

Closer to 100 (or less).

thanks I will be going against 460 Ms some deeres maybe mm olivers. still want to farm her some

thanks willbill but 180d what I got to play with so that's what I got to go with. the 185,d17,d14,and ca are all in used dayly. o and the ihate to say the johnd gets the most use I know but ac parts are hard to find round here.any help on the 180 will be appreciated.
