we pulled the v/c to see if there was any moisture and to run the valves

the white stuff you see is moisture, it probably would have burned off but we wanted to clean as much as we could got.

What duration is your camshaft?

What duration is your camshaft?
cant tell ya, ;)

Ah come on man :D how is my Chevy supposed to breathe as good as your Ford :banghead: with the bigger ports and all when I don't even know your cam's duration? According to the race results you're the one to beat! ;)

rod, the specs are useless to anybody unless they have the same combo, because the cam is a custom for my combo. not to mention there is another ford out there that may try to get his motor to run a little better by using my specs
edit: and i'm not talking about Brad, i have a roller that i took out if he want to try it
-
hey ralph, how do they figure out lane choice for the races? i know the newbys hang back and are on the outside but what about the vets?
-
Drwaw straws.

Yea I didn't think of that... probably not a good idea for someone to post up their entire engine's specs if they wanted to stay number 1... :P
I was just trying to figure how big of a cam it takes to make that much normally aspirated HP, since I am clueless. I saw a cam last night that had 810 lift on it and something like 320 duration at 050. :o Makes me wonder when the valves actually close :D
-
rod, it's no real secret, and engine is nothing more than an air pump and it can only take in and get out so much. so i sent the flow #'s from the heads along with the eng specs to chris straub of stephs oil pans and he did some ghetto math and came up with what i have
-

If its not good enuf for you then.... ??? ;D Brads engine is gonna do just dandy with the hydraulic flat tap. From what I've read in the past it takes a whole lot of exhaust work on the factory iron ford heads to take advantage of a .600+ roller.
BTW, the engine sound great Ralph.

:UPDATED:
Just called the shop that ground the cam...
Some perspective for ya Rod. My old 460 with 618RWHP had a .680 lift by 320 intake 318 actually 314 exhaust duration. The duration actually sacrificed A LOT of power but at the same time gave it a nasty lope with the idle below 1000 RPMs. I intended for the truck to be more of a show mobile than anything but ended up liking it way too much. Nothing like the feeling of roasting oversized tires and keeping up with a stock '04 Z06.
Cam grinder seems to think another 30 HP could have easily been had if the duration wasn't so wild.

But Chevy's intake ports are smaller. :banghead: ;D

cant tell ya, ;)
I bet it's less than 340 and bigger than 200 :-)

less than 300 ;)

The grinder that did my cam recommended 280ish but the lope of the 300+ is just awesome sounding with the hydraulic roller setup.

280ish at what lift?
-
680 lift.
-
Lol, what lift is that 280ish duration at?
-
I dont remember. I got a cam completely overkill for my application. Just wanted the lope... I think that one was closer to 600.
Had to have a little bit of head work done to accommodate the 680. The other setup would have produced more power. I wanna say it was a 610.
-
280ish Duration at 600 lift is pretty narly :D
Bet it sounded good ;)
-
To clear up the confusion tony. The duration was in correlation with .050 of lift.
