Has any body here tried the poston ramair set up on their 350(dual snorkel air cleaner, ducting, front air dam) I saw it in that car craft article about 1-2 years ago "The other 350's" and they said it was good for 30hp OVER the factory ram air :shock: is this true! If it is, then I can only imagine the gain on a car without Ramair (35 hp maybe). If anybodys installed one could you please post your before and after 1/4 mile times?
check around for a thread in the big block forum, they say it's good for a tenth or more. the problem is routing the ducts to the air cleaner.
