TFS Pushrod length?

Just got my set of Trickflow heads intalled on my car along with a FM14HL cam and morel lifters. I was just wondering if anyone had a similar set up and what size pushrods they used. The car has 59cc chambers, which would be milled .025" to .020" and stock head gaskets. They came with 7.700 pushrods but I think they would be to long with the morel lifters which are longer then stock lifters.

I've got the same heads with 61cc chambers, and 7.7" seems to work fine with the caddie racing lifters. How much longer are the Morels?

Yeah we have almost the same setup, but my heads are milled a little more + I have the Morel lifters which are longer, thats what makes me think the 7.7's would be to long. I have a length checker on the way, but it won't be here until next week!

Two issues, one is the Morel is longer (I can see if I can find my measurement, I measured the stock and the Morel from the roller to the pushrod using half the adjustable pushrod to determine the length difference). Second, the Morel uses less preload, mine are set at 0.040". You need to compensate for both of these changes along with your milling, etc. You probably should get an adjustable pushrod and take the measurement, but your length is wrong it if works for the stock setup and likely off by almost 0.100".
