On a stock engine ...nah
i wanted to do that mod and everyone told me not to....waste of money
Better do Headers with the $$$ ...
If you are getting new heads cam and rockers...could be a good mod to
help'em breathe...but for stock heads and TPI intake......its overkill
I got a Holley 58mm one but i upgraded intake , heads , rockers and cam
