High torque 360 LA build camshaft recommendations
Looking for more low end power. This isn't rocket science. You can achieve this really only a few ways.
Biggest factor is gonna be displacement. Another is compression. You need both of these. Without these two things all the cam heads exhaust etc isn't getting you there.
If it were me, I'd go stroker, small (but not too small) cam, decent heads like magnum heads. Small ports aren't the solution here. You still need good head flow. I'd get a nice dual plane like a performer rpm, decent carb like a 750.
And, headers BOOST low end power over manifolds. Long tubes will increase low end torque.
TBH if you want low speed torque you're in the wrong forum here. Jump over to the big block forum :D
