Ok, I'm finally making some progress on my build. Got the engine back from the machine shop and got it put together. Using the Speedmaster stainless, roller, adjustable 1.8 LS set. Had to machine off .125 from the pedestals that come with the kit and since the kit comes with metric bolts you will need to get some 5/16 x 1-3/4 so they will be the correct length. Then I will have to order 8.00" pushrods. Everything looking good so far.

Again I am wondering why you are doing this? A lot of money, time and effort for almost nothing, there are already roller rockers out there for sale that fit with out modifications needed.

Because the ones that you are referring to are 4 times the cost of the ones I am using and my OEM valve train needs replacing anyway so there is very minimal additional cost in replacing my worn out stock stuff with new, adjustable, roller rockers. And most importantly....because I can.

More power to you, but some of these readers will think it some miracle power adder for super cheap which it is not. Be interesting if you post in the end with true cost of time, labor, machine work and parts and compare so we know.

I can promise you, no one reading this thinks it's a "super cheap, miracle power adder", geeze dude lighten up. And true cost? does anyone that owns one of these rigs REALLY keep track of the TRUE cost that we have in them. I'm taking my sweet time on this, working when I feel like it, with hand tools and a micrometer. After I get the new engine in it and broken in, I was even thinking of getting rid of the Holley ecm for the Projection and going with a microsquirt ecm and tuning it myself....if that's ok with you.

Take it easy friend, we all have little projects just for fun no matter cost or time. There are people reading this looking for a miracle power adder for cheap, reading this post from the beginning, there are all kinds of tinkering that can be done, which can be fun if that is your thing. Again, have at it and share what you come up with so you can pass the info on to the next guy.

I'm at $50 for the LS rockers off ebay, $15 for the raw material from McMaster. Hardware is borrowed from work. Lunch hours machining instead of playing on the internet: "free".

Anyway, seat of the pants feel after advancing the cam 4 degrees for more idle vacuum and installing the higher ratio LS rockers: it feels slower, but hey at least I have enough vacuum at idle to activate 4wd, and it doesn't stall as much shifting out of park.

Not 100% sure on that yet. Old valve covers are super nasty right now and I don’t have my correct pushrods, so even if they were clean I can’t run them through the full operating range. If I have to I will get some chrome Edelbrock covers, those will for sure clear. But they do clear the way it sits.

LS Rockers

After using a valve 4.900 long and starting the sweep at the center of the valve stem, I will use a valve around 5" long in all future LS rocker arm swaps.

The LS rocker travels across the valve stem in a wide ark, therefore the rocker has to start its sweep on the intake side of the valve stem.

I am setting up a pair of heads next week and I will try to get some pictures up

Using a .5020-.5050 long or so valve and keeping the valve lift to .550-.600 looks good for a bolt on setup.

LS Rockers

5.020 long 11/32 stem valves in 502 casting heads. No machining, literally a bolt on setup.

Pushrods clear the factory holes with .600 lift, no milling the factory bridge bosses, complete bolt on.

Cut the factory LS rocker stands in sections and use 5/16 x 18 x 2" long cap screws

Witness marks show the starting point and a full sweep with .600 lift

Ok, pictures will not upload and I resized them twice so maybe it needs to be a postage stamp?

Update

.100" long SBC valve with an .080" lash cap or a 5.2" long valve worked out better for this engine with a zero deck and no machining to the bridge pads.

OR

Mill 0.200" off the bridge bosses and use a factory valve
