Stroked 440 combo question

[firefighter3931]

Oldschool, could you post a dyno sheet from one of your 500in builds with the ICH DP intake manifold....i've never seen one on the dyno. Interested in where the tq/hp peaks come in....


Thanks, Ron

Here's the dyno sheet.  The yellow line is the current power level after dyno tuning, the pink line was the base line.  This is on a 68 charger with a hemi 4 speed, dana 60 with 3.54's, and stock steel magnum 500s. 

Check out that gain from adjusting timing and afr.  And look at that torque curve, its like a table. 

engine specs:
13.7 cr
295 cnc sr heads
indy dualplane
1000 cfm AED holley double pumper
tti step headers
MSD pro billet dist.
6-al box
comp. solid roller cam:272/276@.50  .661/.661
1.6 rockers

these are on a chasis dyno.

Very nice OS....killer torque curve. Nice to see the ICH DP pull so hard.....by far the best Dual plane manifold i've ever seen.    I'm sure the big roller cam and 13.7 compression are helping to carry the hp numbers up top. 

What type of fuel are you running in this badboy ? C-112 ?

Should I have my block zero decked for the 440source 512 stroker kit?

it depends on what compression ratio you are after. if you are looking for a pump gas motor i would let the machine shop determine that for you.

yes ron,i use c 112. i buy it by the drum,  (many drums)!

you dont need anything like the Indy heads to make good power...    I built a 440--> 496ci engine with a hydraulic  cam, edelbrock rpm heads, dual plane intake, 10.75 compression, and @" headers...    it made around 614hp @ 6000rpm   and 613tq @ 4500rpm...

indy heads or even ported edelbrocks will just make more power though...    this engine is currently a street only piece.

I figured as much 

How much is that stuff selling for nowadays ? 

Up here in the great white north i'm sure it's well over $10 a gallon

Exactly. 

You need to determine what type of fuel you want to use and build accordingly. The correct piston for a pump gas stroker build will have an inverted dome (dish) to keep the static compression ratio livable with that type of fuel. The head chamber volume also comes into play as well.

So, pick a set of heads first and then pick the correct piston for the application.
