414 Dyno results: Missed combo?

-
There is if you wanted 50 more HP. I thought that's what RAMM said...he expected a bit more.

I will give a full synopsis later this weekend. In short -NO I don't want or expect 50HP more but I did expect it to reach the 500HP mark. J.Rob
 
I'd say with the mild camshaft that RAMM used 488HP is plenty good. He just wanted to crest the magic 500 mark.
 
There is nothing wrong with that damn engine.
The question for us isn't if there is something wrong with it, but rather, can it be even better? Isn't that always the question We are asking ourselves?

Yup. With those heads, would be interesting to see what a cam/carb swap would do.
 
well my track numbers have never lived up to the dyno numbers, but we did dyno with a QF 1050 4500, and I ended up running a Braswell 4150 carb on it. Runs great, I'm having fun, and so far no baby sitting required :) ....of course I'm sure there some loss expected due to trans, set up, etc....

We certainly are always asking ourselves if it can be better. This engine could be better and EASILY. Like I said I will offer my full synopsis a bit later with both objective and subjective thoughts and opinions. J.Rob
 
i'd be curious to know how a single plane intake would affect this motor, good heads, mild cam, plenty of compression. would it completely kill the low rpm torque and only pick up slightly on the top end?
or would most of the torque still be there?

I'm pretty sure this engine would prefer a single plane. I'd love to try an X-celerator on this one. J.Rob
 
I find this thread interesting because Im currently building a 408 with ported W2s that should flow 300+ and a dual plane M1. The cam grind is still up in there air.
I am looking for a similar power curve.
 
I like how that HP line goes up and up and then just simply hangs in there for a long duration. Killer torque line where she counts!

Why?☺
@RAMM have you calculated intake port size/length for this camshaft?
In my car,i think this is a boring engine☺ it will fall over before 5000, not any fun to accelrate when you cant rev it out. Sure its cool when you stump it, it light up the tires instantly.

Naw it won't fall off before 5000, in fact this engine will rev to 6000+ rpm so fast you better have a rev limiter. Most engines I dyno and have experienced in the vehicles after felt like they would easily rev almost 1000 rpm more than what was indicated by the dyno. First engine I dynoed for myself was a 451 B and it was all done @ 5700 rpm on the dyno-you would not know it in the car-in fact I had a 6500 rpm chip in the MSD and thank God I did-it was impossible to shift or modulate throttle. It was on the chip all the time.

Didn't calculate lengths and have done this 4" arm deal a million times. This engine will shove you back HARD with mild gears and a stock converter which makes it appealing to MANY. This engine is the perfect Dr. Jekyl/Mr.Hyde and will surprise the **** out of the new owner. I did a 365 for this owner's cousin that was mild also 438 tq/375 hp and they still cannot believe how hard that pulls in a heavy *** Mirada--He has taken down big blocks and modern LS powered stuff-Imagine this engine with 100 ft/lbs more.

I do know what your trying to say though, I myself prefer an engine with an "extended" RPM range. J.Rob

"414 Dyno results: Missed combo?" was the original question. The hoped for goals came much later in the thread. The basic build is capable of about 600 HP with enough of a cam change.

Cam and intake= different engine. Thankyou Mr.Laroy. J.Rob

That is correct, the post title asked the question w/o disclosing the goal/application, which makes all the difference. Most of us know what heads like that are capable of, but
the current cam/inlet system are going to short that. Buuuutt......it also exposes the "having too much head" argument w/that torque curve. Now those heads on a 273.....OK,
THAT would probably be a velocity/torque killer,...............
