maybe you are asking for to much at 3500lbs. low compression, steel heads, small cam

He is... to ask the times he is looking for in the heat
and he would be lucky to see it in the cool weather

and a 410 gear, it sounds more like a street combo. converter needs to be 5600+

Im intressed to know how much you gained going to sissy trans?

The fact that my incrementals are all inline with eachother is what has me a little upset...I built this thing to run 10.90's and im struggling to even get 11 oh's out of it. I am running IMM prepped and ported RHS X heads that flow 291/212 cfm at .600"...I agree that the converter could have been loosened more, but at this point sending it back out is not feasible (its almost $450 to get it re-stalled which was covered by them this past time, but next time around I would have to pay...plus the 100 bucks in shipping there and back )...However, its definitely an improvement over how it was stalling before

I too am thinking that advancing the cam might not really give me much improvement, if any, at all....but its worth a try right? Maybe the car will pick...atleast I sure as heck hope so...otherwise this winter its back to the drawing board to figure out how to get more power out of this thing.

What's so great about a 360 stroker is that it pulls from 2500 to 6500 rpms. Running a stroker with a stock block beyond 6500 is asking for a short engine life. Just look at NA dragsters. They are packing 700+ HP and their final drive with tire is about a 3.55 rear gear. They don't need to buzz the motor. They race all season long with the same set up and the motor lasts. Rational... you want to make all your pulling power with this stroker under 6400. Try a 1/2" to 1" carb plate. Well flowed 750 carb. 1 7/8 header and play with extensions. Get you total weight down to 2900lbs. Don't know what you have for heads but have the intake port matched to the heads. There is power to be made there. Food for thought. I recently completed a back up bracket motor. Purple stripe 590 cam and kit, port matched M1, 11:1 pistons and a 1.88 intake J head. How about one dyno pass 628 HP. There is more in a J head or the 596 with the 1.88 intake than most believe. Not knocking anybody who does heads but if you read the Mopar engineers reports on the 360 it does not like the 2.02 intake. That's why they choose the 1.88. Can you make more HP from big valve W5 Brodix or Indy head? Sure but think how cheap a J head is and the valve train parts etc.

I too am thinking that advancing the cam might not really give me much improvement, if any, at all....but its worth a try right?

---

Yes, try it, it will give you more punch on launch then you have now.

Then see where your at. IMO , Your going to be closer to your 10.9 then you are now.

After that, my next move for a easy performance increase would be to shave the heads .040 for increased comp. if you have the room P/V clearence wise and pushrod lengths. That should get you there.

A few questions:
1. What is the rolling resistance like on flat level surface? Car SHOULD roll with minimal effort.

2. How long does it take your fuel pump to fill a gallon jug from carb side of regulator? Should take around 11 seconds for your combo preferably less.
2a. What diameter is your fuel line? 10 from tank to regulator 8 from regulator to carb.

3. What convertor are you using?

Im going to do it, I have decided that already that is for sure...How much I am going to advance it though is still up in the air.

---

Well dont just go 2* advance or so. That wont do much. IMO Id go a minimum of 4* advanced to 104, Minimum. Id probably go 102 ICL as a first test if it fits or there abouts. 101 , 103,

I thought about a gear swap as I do want to put a spool in over the winter...But its a street car, and I liked having the 4.10's for when I do drive it on the highway (not often but it does happen)...But then again, this car is becoming more track oriented than anything else.

Would 4.30's even have a noticeable improvement though over 4.10's? Would it not just be better to try a 4.56 ratio instead?

---

You never dynoed this engine did you.. with any steeper
gear your gonna up your trap rpm.... what do your
heads flow at what lift... but RPMs are HP IF your
set up can deliver (as in carb, intake, heads and headers..
have you ever pulled the exhaust yet to see the restriction

Would not suggest going 4.56. You will run out of motor way too soon and trap rpm will be over 7K - and don't ask me how I know. 4.30's might work though - with a 29 or 30" tire.

I wouldnt even consider a gear change for a test improvement. With your 4.10 gear and 28" tires , you can easily swap out and test different slick/tire sizes between 26" and 32" tires to simulate gear swaps.

A 3.91 gear with a 26" tire is more gear then a 4.56 gear and a 32" tire.
