1970 GTO Version 2.0

Question - what is the advantage of running a stock type LS intake and piping the TB up to a carb style breather vs. using a carb style intake converted to fuel injection with a carb style throttle body?

Excuse my lack of knowledge. I can see the carb stypel setup being more expensive. Also, the stock ECM may not like the carb type throttle body.



Any insights?

The single plane intakes are aluminum, so they are heavier and heat up more. They also have shorter runners which hurts low end torque. It would also be hard to mount the MAF. The other issue is that newer LS engines that have the 58 tooth trigger wheel can't be configured to work with a cable operated throttle body. Jeff Schwartz has adapted a DBW throttle body to a single plain before, but I just didn't want to do all that.

Gotcha - I was just curious.

Your setup is sweet. If/when I decide to go LS in a project, I'll be referring back to this thread and may have to lean on you for some tech info!

You gonna have the GTO at RTH this year? I hope - I'd like to check it out in person.

Later,

Yes Sir! I am really looking forward to RTTH. Parsons and I are roomies again and we are arriving on Thursday evening so we won't miss anything. Before the event I plan on:

Installing ATS AFX spindles
C6 ZO6 brakes from Kore3
Doing a make-over on the wheels
New tires
Corner scale the car
