We did a little mixing and matching, but weren’t exactly pioneers in the LA block/Magnum head build. Obviously these rigs dont see much over 4000 rpm so Im looking for good torque between 15 rpms. We’ve finally completed our 408ci stroker small-block Mopar build for Project Track Attack. Personally, I am scared to 4-wheel it with this much throttle response! All it takes is just a little bump in the road to make my foot slip, and there goes my u-joints, my recommendation is to switch to a throttle cable so the torque of the engine doesn't affect the throttle position. Im building a 408 EFI stroker using a 1995 F4TE roller block with forged crank. The amount it took to make the mostly stock 302 go normally will cause the 408 to accelerate like there's no tomorrow. It was a 351M but I bored and stroked it to a 408.
