Stock pushrods are 7.380". My heads are milled .020. So to stay the same length as stock I'd require 7.36" pushrods. I can either go with 7.35 or 7.375". Since in the near future I'll be adding an aftermarket cam (and I don't want to have to mess with the top end then), and they do have smaller base circle I'd prefer to go with the 7.375's. Will the added .015" of lifter preload cause any problems? Thanks.

 

You running the 228R ?? I am almost positive that has the same BS as the 224 You can run 7.4s and be fine

 

stock cam for the time being. Cam will be going in with the 80e and converter. The heads being milled throws things off a little. I think I'm going to go with the 7.375" and I guess it would also be a good idea to put new lifters/trays in on the head swap.

 

Lifters should be fine, trays if you want, they re cheap enough.. I am running milled heads(20k) with 7.4's The lifters will take up that difference..

 

well, the engine has about 80k on it now...you wouldn't recommend new lifters?

 

Well giving 80k, they might be a good idea, but the old ones should still be fine..I assume it would be good insurance I guess I didnt, cause my 6.0 was just about brand new.. Also why are you waiting to put the cam in, I would do it all at the same time...

 

because the cam wont work well with the stock torque converter

 

Sure it will 2 foot

 

Stock push rod length is 7.400". Stop guessing and buy the $20 dollar tool and measure to be sure.
