Going Big Block
sometimes any year block is drilled and tapped and sometimes not. never-the-less its still a easy mod to do. the spoolmount trick can be done, but quadrupple check all the measurments. Shuemacher kits are very nice also, but again you still have to mod the frame mount. with the factory BB k-member you get perfect fit and geometry everytime. a torque limiting strap will take care of any concerns one may have with the d-side mount ripping apart. there didn't seem to be any problems with factory M-code dart motormounts. i stand corrected on the booster thing, factory heads and factory valvecovers you shouldn't have a problem.
