Lateral-g Forums - Dilemma on Engine/trans Combo for my 69 Camaro

I have been looking at swapping out my stock 350hp 396 for something with a little more edge to it. I want to stick with the big block theme. I have decided on a Mark Jones forged 496 stroker....650hp and 675 ft.lbs. The dilemma is what to put behind it.

Option #1 Built TH400 to replace the existing original TH400. Would have the old muscle feel and no mods to make it work. I don't do much hwy driving so it is an option. I have 3.31 rear gears in the car.

Option #2 Built Stage 3 Keisler 4L60 with their conversion kit package. Again, minimal modifications but some work needs to be done to make it work. I am also unsure of how good the parts and modifications are that Keisler does to their stage 3 transmissions. It's a bit of an unknown. I have an upgrade list but am a little uncertain.

Option #3 Hurst Drivelines TKO-600 swap package with their Mcleod dual disc clutch and other upgrades. Due to some packaging constraints, I would need to do a custom Wilwood pedal set up with under dash master cylinder running to a an external slave cylinder on the trans. I know they make good kits and their service is excellent, its just the amount of under dash work needed to make the system work.

Option #2 and #3 around about 3K more in cost and require modifying the car much more than staying with the TH400.

Thanks for the input guys.
