the valve covers i want do not have the breathers in them. so i will put the breather on the oil fill tube. i prefere it that way anyway. the look im going for. also, my truck has a sbc400, a th400 trans and 3.73 rear. i dont need any more low end power. thats why i wanted a single plane intake. i need more midrange and upper rpm power. im likely going to convert the engine to a full roller. and still looking for an old vintage low rise dual quad intake. i plan to run two 390cfm or so carbs if i can find what im looking for. until then ill hold onto the torker i have.
