After building many extremely fast and reliable LSx based engines I have put together our own Eagle crank stroker kits here at HPE. These are all premium parts and can stand up to extreme usage and power. We have made nearly 600 RWHP NA with these kits and even much much more with power adders. Both the Wiseco and the Mahle pistons in these kits are excellent products and for the rest of February they will be on sale for 2099.00 unbalanced or 2199.00 balanced.


These rotating assemblies have:


- 4.000 4340 LS1 crankshaft
- 6.125 4340 H-Beam Rods
- Wiseco or Mahle Pistons depending on App.
- Wiseco or Mahle Plasma Moly Rings
- Federal Mogul 152M Main Bearings
- Clevite CB663H Rod Bearings



We will also be selling some "Econo" LS1 stroker kits that are intended mostly as NA kits or only with small power adders. These kits are somewhat more limited due to piston choices but are also very good deals if you do not need the extreme strength our regular premium kits have for engines making 600hp and less. These are being offered at 1899.00 unbalanced and 1999.00 balanced.



These rotating assemblies have:


- 4.000 4340 LS1 crankshaft
- 6.125 4340 I-Beam Rods
- Probe or Speed-Pro Pistons depending on App.
- Probe or Speed-Pro Plasma Moly Rings
- Federal Mogul 152M Main Bearings
- Clevite CB663H Rod Bearings



Some 4.125 bore kits may add 75.00 to the total. We also offer custom piston upgrades for 200.00 and a Hellfire NOS upgrade on some pistons for 50.00 extra. All kits are mocked up here at HPE and all clearances are checked on these kits even without balancing including pin clearance and counterweight to piston clearance in our own mockup blocks so you won't have ANY surprises when you get them. Having assembled my own stuff at home in the old days I know how it is to not have any way to fix something in your own garage! On some kits however you may need to slightly notch the bottoms of the cylinders for rod bolt clearance although even on most 4.000 inch kits we do not have to. All the above kits use zero to only .015 offset rods and NOT the regular high offset SBC rods that many use. Feel free to email me any questions you may have or call after 1:30pm Central and ask for me personally.

 

To The Top!

 

Sweet deal. Man I wish I was ready for a stroker!!

 

That's alright just remember us when you do! These are all the parts that we have settled on as the ones that serve us best without breaking the bank. The 408 especially is a Gorilla strong assembly overall and is fairly economical too.

The way I see it is using the Eagle crank etc. you can use the money you save to put into something like cylinder heads, valvetrain, intake manifolds and headers etc. that will really make some horsepower. I like the other stuff too and we use it but I don't see it as worth it at all if you are on a budget and you are still trying to go fast.

 

To The Top One More Time For Feb.

 

this is a great deal eirc ..i know my eagle crank has held up just fine ....and i made 595 rwhp uncorrected the other day on yalls dyno....

 

Thanks John, we are currently doing two more engines like yours with one being milder and one maybe wilder with a solid roller or very aggressive hydraulic roller. I am very satisfied with how all of these engines have run with these parts and they are not overpriced either. The solid roller/big hydraulic roller engine may make over 600 RWHP NA I am hoping, especially as well as your's has done. I know with a more aggressive cam we would probably even make more on yours no doubt, not that you need even more power! Thanks for the nice words too.
