Not entirely sure what I am gonna do with it yet...been looking for a GS project . Came out of a72 Riviera that sat for years......guy said he dumped some gas down the carb and it ran for 10-15 seconds.. said it was rebuilt at some point but who knows... looks like it was painted as the soft plugs have some paint flaking off I am no motor expert, know enough to get me in trouble... so far removed the intake, rockers and heads and carefully labeled everything. It looks fairly clean, not sure i have seen entire blocks and heads painted inside and out before. One rocker had some play in it but probably just an adjustment... My goal is to really evaluate it, if core of motor seems good as is, I'll throw in new gaskets, maybe a cam, springs, heads/valves done, TA timing cover/pump, aluminum intake, maybe headers... would be happy with 300 hp if achievable without spending over $5,000 on it. How does it look so far? What should I be looking for? Will get the oil pan off at some point next. Thanks Brad
Interesting. There is a product called "Glyptol" that is great for coating the internals of an engine to give quicker oil drain back and less oil contamination. I believe that is what you are seeing here. Typical paint will be a disaster, flake off and ruin the engine. I'm pretty sure this is Glyptol the good stuff.
Looks rebuildable if it all passes a mag test, has no to badly spun Bearings and the lifter Bores are good. I am not sure that that's GE Glyptol as Glyptol drys more glossy even with no oil on it, but it can be hard to tell from photos. I have used Glyptol and Rustoleum red Enamel primer, both with great success as long as the surface you apply either too is 100% free of oils.
There are several types of inside coating for that purpose. That block is a 73 or newer, so do you measurements of piston sitting down in the hole and cc to make sure you end up with the proper compression ratio, 5k is strong budget for only wanting 300hp, if done correctly think you should be able to for alot more hp for your budget
I'd think you could shave the heads and use a TA 212 cam and get 300HP at 3,600 RPM. It is a low compression motor for sure. Measure everything see where it comes up but I agree $5,000 is a strong budget for 300HP.
"Glyptal" is a range of products with various qualities. Some of those products might be "suitable" for painting an engine interior. http://www.glyptal.com/glyptal_products.html I say that if you DON'T paint the interior, the paint you don't use can't flake off and cause problems. I hate seeing paint inside an engine.
If you get the motors compression to a factual 9 to 1 and run a Cam of between .480" and .500" lift and 225 duration @ .050" then even thru Exh Manifolds I can't see how you don't make atleast 325 hp. It should only take a Intake flow of 170 cfm@28" to make that 325 hp , so your heads have plenty of flow to spare!
motor has aluminum rockers,1972 should be correct for the year,73 and later had the stamped steel rockers.
