Let’s play - What cam, what intake, what carb

448 cubic inch wedge
Factory forged crankshaft
Molnar H-beam rods
Icon flat top forged pistons
10.5 Static CR
Trick Flow 240 Heads

Peak rpm at 6800rpm

What cam?
What intake?
What carb?

Trickflow recommended stuff but solid roller?
Do we win a shirt?

Indy has something I’m sure... put a toilet bowl up top and set it accordingly !

I would approach it differently.

Cam, intake, carb selection would be based on the intended use, and ET target, as well as other aspects of the car itself(exhaust system, stall speed, etc)...... then the HP just ends up being whatever it is.

The stock stroke 440’s I’ve been involved with or built in that 650hp range have all been fairly high strung.
They either had better flowing heads than TF240’s, or “more” of something to compensate for the head flow(compression & cam), or both.

But, to get within the ballpark of the 650hp number(without making any considerations for the support systems in the car or the intended use).....
-mid-260’s roller, .650-ish lift
-TF intake or Victor with some work
-1.400 or 1.450 x 1.750 4150 carb

This one was 11.5cr and had heads that flowed 350.

Racer Brown Solid Roller CCR-78/80, 278/280 @ .050, .680/.680
Victor intake
850 Mighty Demon = 676 HP @ 6,800 rpm
950 Quick Fuel = 699 HP @ 7,000

Looking over the dyno sheets.....the smaller cam in Dwayne's post would be a much better choice.

I’m leaning towards a solid roller, 258/260 at .050

The original trick flow 240 website referenced their 440 dyno mule making 620hp with 243@050. I can’t seem to find the chart now.

Just for further reference we used the Comp Cams XR292R solid roller (254/260, .582"/.588") in the same short block with iron 452 heads flowing 310 cfm, 9.5:1, with an M1 single plane and the 950 4-bbl. It maxed out at 621 HP @ 6,100 rpm and was down to 601 HP by 6,700 rpm. A pair of Trick Flow heads would have made a big difference but we didn't have them back in 2006.

found it, seems optimistic

I would like to have the TF 243 cam to see how things compare and then change cams, but in today’s world that’s a huge luxury.
