Fel pro 1213S, been running them on my 69, 340 dart for 20k miles. Work great
Same here. Also what we used to port the intake and heads. Both the Edelbrock Factory 1970 intakes and the aftermarket Edlebrock bottoms looked the same as well as the Mopar Preformace one I have.
Dont worry I sold at almost a give away price the numbers 1970 one and used a new Reproduction Edebrock and Mopar Performance to port and then polish for a shiny look
