Serious questions about stock 429 rockers and solid flat tappet cam. Warning, very long!
OK, well the saga continues. I am still trying to get my 83 mustang 429 swap completed. Everything was done so I thought. Now I have to open my damn engine again because the guy who sold me the cam told me it was a hydraulic when I indeed found out from the guy who ground the cam that it was a solid (he came to gainesville for the races this weekend). I was all set up to use the stock channel type rockers on my DOVE heads on with the cam. I had to use 1 washer under the posi lock nut to have enough threads to engage the lock. If I put the guideplates in I may have to use more washers and I don't have the cash to shell out for roller rockers. I put in fully threaded studs instead of the shouldered ones that come stock. Everything looked fine geometry wise. Now I need to put in solid lifters. Here begins the questions. 1) How do I adjust the lash on the channel type rockers and what should I adjust them to cold is it .025 (seems like a lot)? 2) Is this going to be alright with a .560 lift cam that will see 6K rpm max? 3) Also is there anyway I can salvage the intake manifold gaskets as the engine has not been run.
I already had to take this engine apart because I found a cam dowel pin on my shelf and got paranoid. The pin was in however! Better safe than sorry.
Sorry so long,
Thanks,
Greg Havemann
