Treuhaft 32-1000 cam
Does anybody have full specs for this cam trying to find out if stock valve springs will be acceptable
on my rebuild I found 3 cracked valve springs which explains my popping
here are the specs I have but I need valve spring specs if anybody can help

Its a Treuhaft
32-1000 lift .400 duration 280 rockers 1.1 lobe center 106 open 34 close 66 intake / exhaust is 66 open 34 close

the valves springs i have that are still in tack, measure 2.2 tall od. 1.25 id. 0.93 wire diam. .158

i can not find any valves that match these measurements. I'm sure that the height has shrunk

stock valve springs are about a 1/4 shorter.

I'm not the greatest at performance building, besides some possible valve float can I use stock valve springs

.009 dist. headers twin solex 40/44 eis carbs 87 mm pistons everything else is stock.

Last night I got the bright idea to measure the length of the stroke between the the highest / lowest
point of the cam lobe on the intake and exhaust lifters. I found that the max. stroke for both is 3/8 of an inch == 0.375

So the rockers are 1 to 1 the push rod stroke would equal the valve stroke right...... 0.375

the stock valve springs are a little over 2 inchs so total travel would be only 0.375 correct

So the the longer valve springs are not necessary
???????????

what do you all think

Stock springs can handle 0,385" lift. But they are most likely too weak to handle that cam duration and lift.

You need to check coil bind on these other springs.

did not think that was a very radical cam. In fact is it not pretty mild

the stock springs I bought measure 128 lb of force at 31mm of compression

do you still think they are too weak

are you worried about valve float.
