new engine combo

strokerman · 03-09-2003, 02:04 PM

getting done with my engine soon, 408w, was .218 .228, .536 .536, .112 lsa, world sr heads cast iron, lightly ported, stealth, 750DP, new combo, roush iron 200 heads, ported, .005 on .in 246, ex .179.2, .006 on .in 262.7,ex .006 is 185.4, 67.5 on the chambers, new comp cam hy roller custom grind, .236 .242, .555 .576,.108 lsa, vic jr manifold port matched, same carb, 1\3\4 hookers, wondering how much power i will have with this new combo, desktop says over 475 hp with 400 ft lbs, we'll see on the chasis dyno this spring.

Sounds pretty bayad, you should post some pics if you can, maybe a video after you get it running?

What are those heads like out of the box? Did you flow them before you ported them? Did they flow the 200 they are suposed to, on the int. side? More? What is the exhaust like unported? Are they reasonably priced? Those numbers are impressive, how much porting did you do? Finally, I don't know much about comupter dyno programs, but with that kind of cubic inch (408) you're bound to make a bunch of power. And that cam looks like a nice choice! Sounds like it will be very torquy. One more question though, why the extra lift on the exhaust sid? They aren't stock ford heads...

What is this going into cause if it's for a mustang it's gonna rock!

hey trevor thanks, the car is a 69mach1 that i had for over 20yrs, getting old man, anyway the guy who ported my heads is unreal, those ports look like glass, even around the valve guides were smooth, i didnt have them check before they were ported, now that i think of it i should of, the cam has little more duration on the ex side, i think that the norm on fords, this thing is going to be a bear on the road i hope, last time had 400 hp, this time hope more, my old sr heads flowed @ .005 228cfm, so i think the roush heads are close.

realize though that it's not just about CFM. Cause if you can't use it there's no point. With that stroked windsor you shouldn't have any problems. By the way flow is measure with valve lift.... ie .500 of an inch not .005 that's 5 thousanths of an inch. You wouldn't even be able to blow your nose at .005 inch valve lift. Nice try though.

Hmm, nice try! (WTF?)

I wasn't talking S to you strokerman, I was referring to the "nice try though" comment.
