It's bored 60 over, stock stroke. Heads are CNC'D Edelbrock Performer. The head work was done over the winter so that and the RPM Performer dual plane intake are the significant changes over the winter. It dynoed at 503 HP before the change and I'm guessing we picked up 50 HP with improved air flow based on nothing.??Akron Don Gallimore------ Original message------From: chuckiiikropkeDate: Mon, May 6, 2019 8:50 PMTo: 1962to1965mopars@xxxxxxxxxxxxxxxx;Cc: Subject:Re: IntakesThat sounds good let us know what you think of the change. Is you 440 30 over or is it stroked? What heads do you have?Sent via the Samsung Galaxy S7 active, an AT&T 4G LTE smartphone-------- Original message --------From: tothperformance@xxxxxxxxxxxxxxxx Date: 5/2/19 5:11 AM (GMT-06:00) To: 1962to1965mopars@xxxxxxxxxxxxxxxx Subject: Re: Intakes Good Choice----- Original Message -----From: [email protected]: chuckiiikropke >, [email protected]: Wed, 01 May 2019 15:06:59 -0400 (EDT)Subject: Re: IntakesThe race car gurus, who I respect as such, told me to take the Torker 2 off my Belvedere and install a RPM Performer which means I'm going from a single to dual plane on a 550 HP 440 race motor. I'll see how that works out in a couple weeks.??

I am not sure about the 2 carbs, it may be to much unless you have a stroker with heads and a cam that will let it flow.Sent via the Samsung Galaxy S7 active, an AT&T 4G LTE smartphone-------- Original message --------From: Mark Negri > Date: 5/1/19 8:27 AM (GMT-06:00)To: [email protected]: IntakesGuys what are these like, dual plane.??-- You received this message because you are subscribed to the Google Groups "The 1962 to 1965 Mopar Mail List Clubhouse" group.To unsubscribe from this group and stop receiving emails from it, send an email to 1962to1965mopars+unsubscribe@xxxxxxxxxxxxxxxxxxxx more options, visit https://groups.google.com/d/optout. -- You received this message because you are subscribed to the Google Groups "The 1962 to 1965 Mopar Mail List Clubhouse" group.
