I got a 1970 challenger convertible, I bought a viper engine/tranny for it, now thinking I want the shaker 426 hemi cause it would be a sin to convert such a beautiful car and also the value would be higher with a shaker hemi but I see some of the prices for them, now not so sure. So what does everyone think would be the best, a twin turbo viper engine/tranny or a shaker 426 hemi? I did get the 15" ralley, dana 60 and the ralley dash already... Its painted in the viper yellow now but I could always change that... So post what you think would be best...
