360 magnum. 1 piston lower in cylinder??

OK.... makes sense for your roads and neighborhoods, and sounds like a LOT of fun. Keeping a wider torque band is really good for that.....as you seem to have found out. I hate to spend your money for you LOL.... but that stroker idea seems to be a good thought for that heavier car in that kind of use. (BTW, my racing background is rally, and a wide torque band is needed there too. Ditto for our spirited driving around the southern Appalachians...I can give you some awesome roads to drive when you get down this way again. Look at US250 west of Staunton VA over to the Elkins WV area. Make sure your brakes are 100%!)

A big part of 'no torque' is what you are starting with in that low SCR LA360. The Magnum is a step in the right direction but it can still stand to have more CR for your use. Example: My son and I built his 340 in his '65 Cuda for the same type of use and we went purposely 10:1 SCR and 8:1 DCR. Pretty much the same springs, Bilsteins (YOU absolutely NEED those!), 904 and the TC is 2200 RPM with a 3.55 rear. The engine and combo is really good for throttle steering out of any corner radius. With your cars extra 600#, more cubes would help but upping a 360 to 10:1 SCR will be a big + step.

And let me spend more of your money LOL. For that kind of driving, a 4 speed would be even better. Getting the engine braking diving into the corner helps set the weight up for better initial steering, better weight transfer on acceleration, and the instant torque to the wheels helps too.

But if you stick with an auto, I'd get the engine CR up and SCR up (via a steep ramp cam to get the least amount of advertised duration), and LOWER the TC stall speed. That last item is to minimize the 'mush' time you spend with the TC partially locked. Throttle steering an RWD car is all about a solid connection between from your brain, through your right foot, and to the torque applied to the rear wheels. Any mushiness in that 'linkage' makes it more uncertain in throttle steering and thus slower to drive.

(That, and the engine braking, are the 'why's' for manual trannies in road racing and rallying.... As a point of interest, the Dodge Challenger slap-stick mode puts the torque converter in a mode where it is partially locked so you get decent engine braking into corners and a super-quick lock up when the throttle is applied. In that way, they made it as close to a manual as you can with an auto....)
