Need a little pushrod help Just out of curiosity if I have a Frutal F11 cam, morel lifters, .040" cometic gaskets, stock rockers, and stock LS1 heads can anyone tell me what kind of pushrod length I'm looking at?
I think these are all of the factors that need to be considered
-Shorter length from less preload
-shorter length from the cometics over stock
-shorter length from the milled heads
-Is the cam base circle the same as stock on the F11 cam?
I'm just looking for a rough estimate because I have a pushrod length checker on the way. Just curious... Thanks guys

Yeah, but with the heads milled to 62cc (I think that's .020) and the.010 thinner gaskets, you've made most of that smaller base up, haven't you? Nevermind, just read the smaller circle is .100, so .....oh hell...

Don't know if this will help. I went from stock heads with Crane rockers and a lifter preload of approximately 0.120" to Dart heads and a lifter preload of 0.40". GM MLS gaskets for both and the Darts are supposed to set up the same as stock. My pushrod length went down by 0.100" from 7.250 to 7.150". Just the difference in setup of the Morels is probably going to account for 0.070".
