Car is slow...
Depends on where your going with the combo...combo...combo and combo...are what's important..forget dyno numbers with stalled autos...For a stall now try Yank SS3600(re-stall if you go bigger combo). PI 3200 (3800) from what I here on a built 350. And, Fuddle line in the 3600 rpm area...All these you can re-stall later to a higher number if needed.
Alright, so I get the converter, its gonna help in the 60ft right? Im pulling 1.7's on motor now and if I upgraded its only gonna get me 2 tenths if that over what I have wont it? Right now it seems to leave hard to me, will a bigger converter help midrange and higher power or just low end?
With a 108 trap speed you'll do maybe 1.65's with good traction (new verter). However your mile an hour will most likely improve because of using that cam with such a tight verter. A cam with the numbers I threw at you "could" give you maybe 2-3 tenths over that cam you have selected....Remember the combo part...You, right now do not make power high enough (rpm) with that cam to be usefull. Go with a smaller cam on a tighter LSA would kick up your 5K-6K power a lot more (where the new verter would like to drop too). Your probably dropping to 4000-4200 rpm on the shifts with what you have now, and that's to narrow of power band with your heads/cam combo, hence no trap speed or good ET.
Lets not make this our private message forum...I will say that better heads, more verter will do wonders...As far as cam goes a "306" is good (manual car cam) but with 112 lsa you can do better for an auto...A lot better in the mid-range. And, that's what it's all about... Talk with the cam grinder guys I mentioned and you will be enlightend....
