I agree with SMCKA - the 244 is for me. If you have good air flow and large carbies (twin 45's are nice) this cam will feel very sweet between 4500 and ~8500rpm. I use standard botom end and dont have any problems on dirt - may be harder on it doing circuit. If you have the $$ it might be worth going looking at a steel crank in the long run - depends on what your focus is. Hope that helps.

Cast pistons are the weakest link due to oil drain back design, the sides fall out of them, followed by the crank.

FF engines crack cranks due to constant high rpm, which is only 6800-7000rpm, they don't break pistons as the genuine Ford pistons are not as poor in design as the aftermarket items.

If it's just a fast road engine spend the money on pistons and you should get decent life from the crank.

The 244 cam runs out of puff at 6500rpm if put in correctly and run fine with 40's, the 234 will run well with a 32/36 or twin 40's.

That's not what kentcams.com says nor is it my experience using this cam. I think you may be thinking of the 224? I find the 244 dies off at about 8000 but is useable still till about 8500 if need be.

(The 244's a very nice cam to run in a 1300 if treated like the dirty revving little monkey it so wants to be. Again, dont expect a lot of life out of her but ... )

I was unaware of your commercial attachment. I am just speaking from my experience and info from Kent in the UK. Nice to know there is a local contact. Thought you may have made a typo or similar is all. Didn't mean any offence, I'll keep my opinions to myself. No problem.

No offence taken and no need to keep your opinions to yourself.

The 244 is brillant cam however 2 things it shouldn't do are make power to 8K and wear out quickly.

If your wearing it out you need consider the oil your using and valve spring pressures, not enough will see float and the follwers hurting it, if your making it to 8K that won't be your issue, too much and you will wear it out as the oil can't hold the pressure and squeezes out leading to metal on metal contact.

With good oil and using Kent springs fitted correctly this cam will last for a long time.

my 244 kit came with double springs.

I don't only sell the cams I use them in customer engines and with the counless number I've fitted I can say in my experience they don't make power beyond 6500, they are all dynoed on the same dyno with the same tacho.

Some reasons they don't power beyond 6500 are:
duration too short.
Lobe seperation angle too tight.

Some reasons why people may think they work beyond 6500:
chokes too big.
ports too big.
tacho doesn't read correct.

I don't use this cam in competition engines as it's too tame and the cams above it will make more top end with similar torque.

Why rev it that hard if you don't need to?
