I see you have it planned, but just for discussion sake, since it's souly a racecar, maybe cut a hole in stock hood, and let air filter sit in 135 MPH wind. Same as cold ram air, and avoid all the plumbing over the engine. Smokey Mt Frank In a message dated 7/22/2011 12:22:17 P.M. Eastern Daylight Time, rbuck@xxxxxxxxxxxx writes: It's needed. The carb won't clear the hood with the single-plane manifold and 1" spacer...not to mention the cold air intake: Alla that stuff brings the top of the air cleaner about 3" above the normal hood line. The hood has a 4 3/4" raised section. I figgered 6" was overkill. :) r On 7/22/2011 9:54 AM, _STILLFRANKSFAULT@xxxxxxxx (mailto:STILLFRANKSFAULT@xxxxxxx) wrote: Is the raised hood a necessity, or for looks?

The O/P at idle is around 10 psi and runs at 40 (when hot) at around 2500 rpm. It's about what I'd expect in a motor with that many miles on it. Last nite I was gonna install the glass hood on the race car, but decided I'd looked at the peeling paint on the nose for long enough. I scraped, sanded and cleaned, then gave it a quick shot of black: The lens kinda distorts it a bit, but it looks like what it is: a rattle-can job that covers the cracked/peeled areas. "Better'n it wuz." ;) I'll paint the underside of the hood silver and the top flat black for the time being. r
