Wow rumblefish! That was quite an explanation and I thank you for it! Made perfect sense. So if I go with that carb you suggested earlier (
http://holley.com/0-82851) any suggestions on what jets to use?
Glad you understood it. Sometimes, I ramble in circles and never get my point across. I was tired when I wrote it. And worried I didn't make myself clear.
On jet size, sorry, no suggestions except, start with the OOTB and then go from there. A 02 sensor in the exhaust pipe(s) will tell you where you stand for the quickest method of tuning the engine or a trial by error at the track and reading of the plugs and taking down notes of how the car runs in addition to the time slips.
You know you did right when the time falls and the speed rise's.
Get a jet kit to start.
So with this combination of parts I listed in the original post, what kind of power/torque could I expect? I've been told everywhere from 400-500hp and the same for torque. Would I be able to get my dart into the 11's? I'm coming from a warmed over 318 auto so it would be nice to boil the tires in 3rd gear with this stroker!
I'm not really sure about taking a guess at power levels right now. Stroker's tend to throw me off. Due to not messing around with them, it is actually a bit out of my league to take a guess, and be some what accurate about it. So, I'd rather not comment on it.
Some of the other guy's can pipe up and add 2 cents on it. I'm sure there is a few guys here with a similar combo. The best I could do is run a very general "Desk Top Dyno" sym if all the numbers could be plugged into the program. Being the DDT program is , I guess about $40 these days, go get ya one and play with it.
Be aware that it is a general program that is fairly accurate if you understand how it works and it's short comings. IMO, the program is a excellent learning tool to see how things change and what effect it can have on a dyno curve. There are more expensive programs out there that are more accurate for a price. The home hobbyist will have to decide for themselves if it is worth it.
If you want yo drive it around on the street and not mess with the rich cruise a 950hp has, put a 4779 750dp on it and go. It will make almost the same power and have a better cruise Air/fuel.
There is a lot of truth to this! I have noted time and time again that a race is more often won or lost at the line rather than the power made by the engine. With this in mind as well as your intended usage of the car and the question of carb size at hand, the choices are to split the race carb size and the super street docile carb size. This is where I came up with the 850 on a 416 cube engine.
A 950 (or larger) carb will provide the best power, but, it may (Notice the word, "may", a lot like "IF" and "should") cause a slight low speed drive-abilty issue. A lot is in the tuning of the carb, timing in concert with the parts being used. This can be no small task and your abilty and available helping hands abilty is an unknown factor. Enter error on the side of caution to fit the parameter of the engine and question.
A smaller carb, like the 750 will provide a little less HP on the top end. But the smaller primary throttle bores will have the air rushing quickly through and this helps atomize the fuel a little better. This combo helps a lot in drive abilty, response, torque and ease of car movement.
On a smaller engine, a 360 of approx. 400 HP, the difference between a 650 and a 750 carb was 10 hp. You'll never feel it, never see it at the track, or barley but will notice the smaller carb responds better due to the quick velocity through it.
(The cam specs were about 10* smaller than your current cam listed above and the rest of the engine was equipped like yours.)
I'd consider a 750 for your engine to be on the small side, but totally doable, a total drivers carb with you missing some top end HP. To what tune the total amount would be, I do not know. You do have a lot of cubes.
And because you have 400+ cubes and a decent cam in there, I step up a little bit on that and the 4spd.
4spd cars tend to be able to handle and like more cam, carb and gear than there automatic trans counter parts.
rayer: All hail the 4spd! I love mine and miss it! :sad6:
