300 hp slant w/turbo... suggestion

If you really wanna run high 12s in a A body, the simpler, cheaper, and easier way to do it is with a junkyard magnum 360. Id say even doable with a magnum 318 also.

If you just want a ho hum car like everbody else's that is a good way to go.

But, if you want something that will run about the same, but garner all kinds of attention from onlookers, both at the strip and at a show, go the extra mile and build a slant motor... They are so rare as to be real attention-getters.
