383, AFR heads, TPIS base, siamessed runners...427hp???
I read in the TPIS book that 427HP is possible with this setup...does that sound realistic???? I need todo a motor this winter and was wonder what would be the best setup for around $5000ish that would put out a minimun of 400hp
I already have the TPI setup...so just need the motor....will 5K be enough???
