That’s still a loaded question. Custom grind rollers are best. If you’re still using the OEM FI, there are some cams that don’t require to reprogram the PCM. However, you truly must have a solid plan. If not, the 360@ Magnum gets pricey. Towing? this comes down to your budget. Trust me when I say, call John at Southeast Performance. The EFI in this system is pretty good. You need a cam that gets all the power down in the low RPM band. The 46re needs some attention too. 5 disk drum and 5 or 6 pin steel gears, shift kit, OD New Spring. I also installed al the billet items as well as the modified press reg.
Stay with a 114 LSA. If you’re towing, you need vacuum.
Stroker? 10:1 compression will be good for low end torque, power and efficiency. OR....get a supercharger.
If you go nuts, a simple rebuild with forged slugs balanced internally and supercharged. Torque and power low to 4000 rpms. Call John. Southeast RT.net.
