Ok engine experts, here's the newest dumb thing I'm cooking up.
I successfully recreated the 2.9 phenolic intake spacers. Now I want to recreate the Sven Pruitt / Pat Kunz "free floating rockers."
I got my spare heads and rockers back. Finally.
This should be as easy as measuring the gap filled by the springs, applying the Pruitt specs to it, and having a set of the four made, correct?
I'd think that every gap on every set of rocker arms is probably going to be slightly different. Maybe. I have the spare 86TM heads here with arms, and the set of 89TM rockers and heads that are on my truck. The plan today is to measure both and compare.
If you have a 2.9, and the time, could you please take a measurement of at least one of your rocker arm gaps that the springs fill? I want to get a few side by side comparison to see if there is a general measurement that universally applies. I'll post my dimensions below. If any of you have an opportunity, could you please do the same?
As soon as I have a set of dimensions I'm comfortable having produced, the plan is to have these run out by eMachineShop so that others can have them made readily. I'll post the cad files here and see if I can get them in the tech section for all to use.
Let's unearth this relic!
