Inquiring Minds Wonder:
We love pictures, and yours are great but....
1) Did the machine shop grind the valves or just reassemble the heads?
2) You say "Crank came out .10 for the main and .10 for the rod. Everything else should be standard." What is "Everything else?"
3) You say "I don't think they even touched the camshaft because it was perfectly fine." What would you expect the machine shop to DO to a camshaft, and why would you even send it to them? Sounds like you're planning to re-install the stock cam vs buying an aftermarket, so why?
Just trying to understand your process, and not trying to be critical in any way but answers to all three questions would be appreciated.Roger
Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.

My questions remain active, but I had a thought about your camshaft. You mentioned earlier that you were getting rid of the EFI, which I'm assuming (though it's dangerous to assume) means that you're also getting rid of the ECM/Computer too, right? (Question #4, added) That stock cam grind is for a variable timing setup, with the total advance mapped against RPM while considering the A/F ratio, barometric pressure and knock sensors. I'm thinking that it may not be the best profile for a fixed curve distributor, but I'm not really sure. At a minimum I would talk to a Tech at one of the aftermarket cam companies. Perhaps one of the others who are more versed on cam selection can chime in after you confirm or clarify your intent on your engine build?Roger

The stock EFI / electronic controls cam won't even be close to optimized for the engine, going back to a carb and non ECM distributor change the cam requirements significantly. I would question the logic of putting a used cam and lifters in a fresh engine anyway, normal wear and tear for a bunch of street miles have taken their toll on the components, I'm sure.Yesterday is history, tomorrow is a mystery, Live for Today!

JimBeam, you seem to have a problem replying to direct questions that are posted, and instead post general statements about following YouTube Videos for your trusted advice. In the latest post you show a box of miscellaneous parts, saying they are all cleaned up and good to go for reassembly, including the roller lifters. Do you not understand the importance of putting a lifter back into the same hole it came from, to maintain the roller to lobe match if you're re-using a cam? Are you totally ignoring the advice that your stock cam is junk for a non-computer controlled engine? If you're relying on YouTube Video's why are you asking for advice here, only to ignore it?
Can you answer these questions for us?
1) Did the machine shop grind the valves or just reassemble the heads?
2) You say "Crank came out .10 for the main and .10 for the rod. Everything else should be standard." What is "Everything else?"
3) You say "I don't think they even touched the camshaft because it was perfectly fine." What would you expect the machine shop to DO to a camshaft, and why would you even send it to them? Sounds like you're planning to re-install the stock cam vs buying an aftermarket, so why?
4) Are you doing away with the stock ECM/Computer and stock distributor?Last edited by rspears; 02-26-2022 at 03:42 PM.
