Aah should have freshened the 305, cool car although I might be biased, the under coating you used is paintable, I did the bottom of my car with it to kind of refresh the factory black and then reduced gloss black Rust Oleum paint and gun sprayed it over top after it sat a day, it's been a while since I did it and it still looks good. Oils and road grime stick to that undercoat bad without a top coat just some thoughts

olds307 and 403 said:You will be around 9 to 1, mild cam would really wake up that motor. What timing chain did you use?
olds307 and 403 said:The stock cam is plain awful. Under 200 duration and .400/.402 lift. Even a cam like a generic 204/214 .448/.472 cam is a step up and cheap. I put mine in the advanced position on my Cloyes timing set. My car is strong with 7.9 to 1, your car should be much stronger, why neuter it?
olds307 and 403 said:Yes, cam degree. It is best to degree the cam with a degree wheel to make sure your timing set is accurate. It is much easier to change the cam out of the car.
