If you’ve read our article on cams, you already know there are only a handful of skilled cam profile designers in the field. Some have a better understanding of the physics at play than others. Up to now, professional advice on cams and valvetrain wasn’t available to the offshore powerboat enthusiast, professional racer, or marine performance engine professional. If you did get advice, it most likely was from someone with a vested interest in selling you a camshaft or some other part.
That was, until now. Allmond Marine is proud to offer the following engineering services:
Cam Profile Design
You can have truly unique profiles that take advantage of your engine’s geometry and respect its limitations
Answer questions such as:
- How much lift can I get with this duration?
- What should my max RPM be for this combination?
- What is my peak loading?
- When is my lash adjuster at risk of pumping up?
- Can I run this cam with my wet exhaust?
Finite Element Analysis
Stress visualization via Finite Element Analysis is a critical piece of your engineering toolkit. If you have a part or assembly that cannot fail, or you believe your system is overdesigned, contact Allmond Marine for a consultation. You might be glad you did!
Valvetrain Consultation
Answer questions such as:
- How can I lay out this valvetrain on my cylinder head for the best performance and durability?
- Are my valve stem diameters appropriate?
- How much installed height is best?
- What would these pushrods do for me?
- How can I improve spring cooling?
Valvespring Compatibility Analysis
Answer questions such as:
- Will this spring work with my cam?
- Am I at risk of spring surge?
- Is there a better spring for my combination?
- How do I reduce my valvespring loads?
- How can I improve durability of my valvetrain?
Valvespring Estimate

The calculator above is not a substitute for proper engineering analysis – it is for estimation purposes only and is not valid for profiles asymmetrical in the negative acceleration region, or for “cheater cams” having a near dwell at max lift. It also does not consider pressure differential across the valves (turbo / supercharged applications). The calculation assumes that valvetrain separation (lofting) is not desired.
Failure Root Cause Analysis
Answer questions such as:
- What caused this failure?
- How do I prevent this type of failure?
Dynamic Measurement Analysis
Some shops are lucky enough to own a dynamic test stand, the Spintron is one example. Other shops rent dynamics test time through another facility. Either way, valvetrain testing time is very valuable. Allmond Marine has many hours logged in analyzing dynamic valve motion measurement data. Let us review your test data, or help you design your tests to make the best use of your test time.
