LA 340 Intake Manifold
Hi I thought I would post a new thread on some specific questions I have regarding intake manifold for the 340.
My 340 is in a 1970 Sport Satellite. The engine has an unknown cam and 12:1 forged TRW’s and I believe is solid lifter. I plan to rebuild it for the street. I do want around town performance and just want to have fun with it and be able to do a burnout and sound good (which it does as it has long tube headers).
It currently has a nice M1 and Holley 4150 650 double pumper non vacuum. With an ESD dizzy.
I am trying to plan for the future but do what needs to be done now as I go. It’s an automatic and the converter is unknown as well and probably needs to be changed.
That leads me to the intake manifold. Not sure the M1 is the right manifold for this setup/car? Will it be ok at lower rpms around town or am I sacrificing that?
Also I need to add a vacuum port as I have power brakes and need one for my PCV. I would have to drill a port. Also height is critical as I am installing an Air Grabber hood and it may be an issue not sure right now.
So wondering if I should fork over and buy a different Intake Manifold that would generaly be a better solution or is the M1 just good enough and save the money and drill and tap a port and hope the hood fits……
Thanks for reading and taking the time to reply.
