head gasket

Max Simpson is the only guy we have had heat treat our rods. Zero issues with his work. Good choice there.

Changing the low side gears will require removing the clutch shaft and gears from the torque housing. Not a 15 minute job but better than installing a new 3rd gear in the transmission. By my math if you would install a D19 low range set up, your 7th gear would be 10.25 MPH @ 2200 RPM with 18.4 X 38 tires - 13.97 MPH @ 3,000 RPM. Something else to consider would be installing D19 Final drive gears which are 8.5 - 9% faster than 190 - 200 finals. I'm not sure if you can do this with a 200 rear or not. Can be done with an early 190. That would make your 6th gear about 7.8 MPH @ 2200 and 10.63 MPH @ 3000.It has to be parts from a later D19 - not sure of the serial number break. The splines on the bull pinion shaft have to be correct to fit the differential gears.

I agree with Larry, if you can find a 426 intercooler make an adapter plate between the head and the 426 cooler and bolt it on. Manufacture something on each end of the core to enable yourself to pump ice water through it. 40 GPM pump or bigger pump. 1 inch fittings and hose. You can do the same thing with a 7020 intercooler but the surface area of the 426 intercooler core is much larger thus it will cool the air better. Another option would be to buy a 1000 HP air to water intercooler from Precision (or anyone with a bar and plate type core) This will bring your charged air temps below the ambient air temp. Same water pump and hoses. Better than the 426 cooler by quite a ways. See link.

	Feel safe at 3000 rpm without doing more balancing

	Balancing engine parts is always a good thing. Do you absolutely need to have everything balanced to run 3,000 RPM or even open RPM - no. The 12cm housing and head work will help you. If it's a gated housing, tie the gate shut. Not that you would have to do it, but an intercooler will increase HP and FT Lbs. as much as any one piece you can put on it especially if you run ice water through it.

	The 99 , super99, and 990 all ran 3-71 Detroit's, 1900 and 1950 ran 4-53's, none ever came with a 6-71! Thats a lot of motor if they are tuned well with a good windmill on top!

	If your connecting rods are properly hardened you will not have any issues no matter what turbo you choose or what the boost is. Be sure to use new rod bolts when you assemble things. If you run the HX35 with the 12cm exhaust housing and the gate tied shut you will see 45 - 55 lbs. of boost. That should be just fine with your hardened rods. Bob, you had the HX35 on yours when the connecting rod failed if I remember correctly. Edited by O.P.S. Heads - 19 Apr 2014 at 10:22pm

	Yes, use a gutted 7020 manifold, if you are allowed to run a intercooler, easy way is to make an adapter and use a 426 cooler and pump ice water through it.

	If done to the right hardness, and Max does them right, the stock Allis "Japan" marked rod will give no problem as long as good bolts are installed. We have ran as high as 200 lbs of manifold pressure on our 180 light supers. We have run 3 turbo's and 3 pressure stages consisting of 3x3.4 on manifold with 3.4x3.75 in middle and a 3.9x4.25 on top with a lot of fuel on a 340 cu in setup. We have turned 6000 rpm with Indy Cyl head. Have never bent a rod. Did explode and split a block once, but an external tie bolt system we fabricated has eliminated that problem. Too much rpm will constantly kill the center main bearing, so counter balancing the crank is a good idea. Using Darton sleeves and Ross pistons allow us to run 1400 to 1500 degrees of exhaust temp with no problems. Seal tec wire rings and a copper head gasket are a must for our application but we did run a stock gasket with wire rings when we ran 2 chargers and kept boost at 140 or under. We feel we have pushed the 301 as far as possible. Ran 25 hooks last season and only problem we saw when disassembling engine this winter is the hammering out of pin bushings. Also a tip to make rod bearings take the abuse is to fully groove the main bearing bottom halves so the rods oil a full 360 degrees. And another tip is to get rid of the water. Run a dry engine as it eliminates a nuisance. Hope this helps answer some questions. Happy pulling Allis Guys!

	What if I am replacing a bad head gasket on a stock unit, do I or should I use a copper?

	an easiest way to adapt the 426 intercooler to the 301 is to use the 301 manifold- and a 426 off a 7040 for example and saw openings where needed and weld the two together flat sides facing outward. the 426 bolts to the intercooler and of course the stock 301 to the head. Otherwise one needs a thick plate, precision drilled holes, counter sunk bores and then drilled and tapped holes.

	I also remember seeing 2 intercoolers bolted together with a pipe in and pipe out direct into intake manifold on a 220 many years ago. Also remember seeing one turned cross ways behind the block. Always loved the innovation of gearhead pullers.
