Re: Clover Lapping Compound

Prussian blue to check a valve job, blue the valve, tap on seat, clean the valve, tap on seat again & the b...

Re: 289 Build Help

Choice 1 Remain slow, but not quite as slow. Keep the LONG RUNNER intake, and cam accordingly with a hydraulic roller around 220 @ 0.050" on the intake. May as well keep the 3.50 gear. Won't be much faster. Will run like a lightly modded original Fox body mustang from back in the day. (pretty much ...

Re: Comp Cams passes off 50 year old technology, as "New" cutting edge tech.

heck, why not sell 50yr old tech. you can see it right here on this board how many guys still want to run 30,40, and50+ years old cam designs. its beyond futile to run ancient tech, but if you can sell it, why not?? hard to blame a company for selling old junk when you cant bring folks out of the 60...

Re: Edelbrock's 500 HP 383 Crate Engine

Their entry level rv type cam kit costs $100 more than the same cam from Elgin, and it's a good guess it comes from the same source. It's not just a guess.

30+ inches, its not even a discussion. as long as you can do it within your budget bigger wins.
