Yeah when run out of rope, but when you can just bolt something else on and get 5-10mph, 40hrs ain't worth 2mph!...:rolleyes:
I don't think you'd never see 110% ve on this build.
Agreed, but.....
That's actually a decent % to use for carb sizing on a single plane intake. I like to use 110%-130% on single planes and around 130-150% on dual planes. The larger % for engines with great heads/ good compression / modern cams / good modern intake.

Educate me on this.
Do you mean dual carbs, or dual plane:confused:
If someone is running a 540 at 7,000 rpm's my math shows 1,094. If I multiply that by a VE of 150% I get 1,640 cfm's. So that's a "minimum" of 1,640 cfm's to achieve the full potential (?) from the engine. But a built 540 at 7,000 can certainly use two 1,050's or 1,100's couldn't it:confused:
Or would you recommend two 950's for that combo?
Just asking . Thanks

Thanks for replying, made me notice a typo I made in my last post above.
I meant 130-150% (not 140-150%) on dual planes. Yes, dual plane intake manifolds.
BTW: a stock or low performance or old outdated dual plane does not really conform to this. I'd stay same as single plane of 110-130% on those.
? probably upwards of 7-7500rpm. Rock solid bottom end, still deciding on a cam. I just know I want to get rid of the air gap dual plane intake I have now.
Sorry for the typo. Its going to be a 468. George at Clay Smith is doing the build, he is calling the shots and says the dart intake should be fine for what i'm doing. He said today the cam should be around a 620 lift.
the engine is going in a 75' Hallett Baron Sprint with 15 over gears and a 11.5x14 prop. hoping for 500 or so hp. we'll see. Just making it loud quick lake boat:D
I am very interested in the Dart intake, is it going to fit a standard deck od is it for a tall deck?
The Dart intake, that I have, is for a 9.800" Deck.
468@7,000-7,500@500HP=:(
Even at 9.5:1 you can get way better than that. Make sure you use a good set of heads on that thing. It will pay dividends.

Heads will come later. Kind a shot my budget on the bottom end. I think this boat will be plenty for now, just getting started with my first v-drive flatty.
