[DeTomaso] 351C push rods

[JDeRyke at aol.com]

That will be a semi-custom pushrod, and if you're going to spend the money 
for such, first I'd get an adjustable pushrod (one only) to see if the ones 
you need are of a certain length for correct geometry. Some lifters have 
their seats at non-'stock' height so that alone calls for different length 
pushrods, and multiple valve jobs plus head & block squaring can change things 
too. 
Second, depending on what cam & springs you're using, consider a thicker 
pushrod wall for a little more stiffness. Stock '70 Boss pushrods used 0.060" 
walls but 0.080" are about as thin as you can buy today. All this can be 
selected in custom pushrods. I've used Smith Bros, but there are many others to 
choose today. Good luck- J Deryke
