Thread: 429 question - hey EriK? Dave? Anyone?

Roller rockers would be ok, but not essential. I would have the heads machined for regular rocker arm studs and go to the adjustable rockers and a set of guide plates along with the correct length pushrods. As Tech mentioned, the Crane site lays it out very nicely and in plain English..... or just say to heck with the cast iron heads and spend the big $$$$$ on a set of Edelbrock Performer RPM heads!!!!!!!!!!!!

Thanks guys! The crane site is great. It explains a ton of stuff. My problem is what is a rough idle? I'd like to get some HP and the engine is 11.0 to 1 compression stock. So I'm not sure how to proceed. It will be a weekend driver only, mild performance build, not too tame, with enough get up and go to feel like a hot rod, versus my toyota truck. Pretty confusing to figure it all out.I've been told the 1968-71 429's put out around 350 hp. I can't find any site to confirm this, and have heard huge variations in actual HP. I would like a smooth idle engine with umph to move when needed, but will never be racing it!

I got you confused with Paul Kane. But advice is advice thanks, all of you. I'll spend some time on the crane cam page, and go from there!

have a set of ford iron heads in the shop i set them up with guide plates and use bbc rocker studs i go with adjustable valve train any time i can it has not so much to do with the setup height of the valve stems for the right preload for hyd lifters but if the engine has been deck or heads have been milled they could be going up or down hill if not tru deck and other things to so i go adjustable
