The first round of changes are already done and we are about to put it on the machine next week. Its a bigger valve than what we currently offer and some other tricks for a new hp here and there

Would the H22 shortblock with the 100mm crank be close in price in comparison to the B series stroker shortblock price or is it a bit more for the girdle modification. Just trying to get a ballpark on price.

$3400 Like the B and K Pro kit if you want this setup with this long rod and short skirt piston setup

What about using a closed deck H22 block with a dry sleeve setup to save on some costs. Plus I know where I can get a closed deck block. My brother in law has a closed deck H22 with dry sleeves well over 500whp for years now with no issues.

Woa, that is a crazy good price.

That would be fine. We just make the piston to the bore size that you need

Whoa. How have i missed this thread. More importantly, why did bently coop or sleeper not tell me about this lol. This is amazing and I'm excited to finally see this happen

Would you say that to reach 400 the ports and chamber need to be welded? hard to tell from your pics but the piston dome looks like it is made to fit the h series chamber specifically eh? do you offer those pistons for sale or only offer in builds? it's hard to tell from the website i only see the wisecos listed.

Really great build, long live the H series

What made you guys choose web cams over other cams??? I have never seen anyone using web cams fornallmotor so this will be interesting!!!!!

4piston

It was a piston specifically for this build. For 400, more airflow, more camshaft. It will be another build with a little more $$ behind it before that happens

Availability and build schedule. We wanted to put a very aggressive camshaft in the engine, however the customer wanted a Pro 3. Pro 3s were out of stock, and they needed the engine to make a race. We try very very hard to meet or exceed build schedules...there is a lot of flim flam in this industry taking way too long on projects and dragging customers along. We pride ourselves in busting our asses to meet delivery schedules. We called Web and discussed a more aggressive cam that would still work with this spring and rocker setup, and they had cams sitting on our build table a few days later. Ironically we worked overtime and got the engine completed and then it sat here for several weeks waiting for pickup LOL!!!!

Putting some money away. Does the shortblock come with anything on it like oil pump, Balance shaft removal, oil pan, etc? Also should you use these aluminum rods in a street build, or would we be better off going with steel?

4piston

Just depends how much you plan on driving it. If its normal transportation to and from work in all types of weather, get a steel rod. If it is a car you are going to take out on the street when the weather is nice and you just want to cause a ruckus on the street from time to time...aluminum is fine.

SpoonH2B

Luke do you know if they will share dyno graph or times at the track???? I want to hear their review in this set up.

4piston

Im sure they will. The engine is on a boat now, but should show up soon

I picked up a block and a head the other day, probably get the sleeves put in this spring and maybe drop some stuff off when we are down racing this summer. Figure the next step for power is a stroker but I'd rather stroke the H than the B-series to make the most power that I can. What kind of labor to build the bottom end supplying your parts?

ESP.net

Steel Rod you won't have to do as much clearancing since it will me much less wider. A Steel Rod will be able to do much bigger stroke then a Alum Rod. Common Sense.

What are your thoughts with oil squirters and power? Specifically in that the oil squirters may create more windage cloud and drag? If the engine has very bad RS Ratio, would you recommend leaving the oil squirters? Have you noticed a difference in oil pressure with or without them? Thank you

4piston

We build a lot of steel rod engines, and we tend to stay away from them on some of these very aggressive fuels that guys are using now. The huge cranks move the rod journal from an overlap position in relation to the main journal to an overhang position...its very hard on the crankshaft. The lighter aluminum rod is a lot easier on the crank when launching the car because of its weight and its shock absorbing properties. If this were a road race engine on conventional racing gasoline, we definitely would have used a steel rod with a weight greater than 470 grams.

We put squirters in an engine purely for temperature control. Most drag race engines we block the squirters off, but similar to my post above...some of these fuels get stuff REALLY hot. With that heat, you can swell a piston up in the bore on a single pass and scuff it to the point that the engine has lost a significant amount of power. So you run more wall clearance to accommodate this growth of the piston. If we can cool it down, we can run a tighter wall clearance and make more power for a longer period of time. If I'm building an engine for an IFO racer who will run FTW black, it will absolutely be setup differently in terms of clearances and oiling than if we build an engine for say....the new OGS spec methanol all motor class. That is one of the challenges of this fuel stuff...you can't optimize for BOTH. We have to find middle ground between building a nitro engine and building an all motor engine and it can be difficult.

Hell yeah !

4piston

I should add to that....we also use squirters on dry sump engines that pull lots of vacuum and we use different pins. big vacuum will suck the oil right away from the pin.

Awesome additional information. Many thanks for coming back just to note that.

Any updates on this build?
