LA 340 Intake Manifold
Hi RF thank you for taking the time to read and teply!
No worries. Everyone here likes to help.
I installed a Suregrip 355 rear gears and its fine. Wish I actually put a 410 in it. But its not for long highway cruises.
3.55’s aren’t exactly a Hwy. gear ether, but they’ll do.tire size has a roll in this.
Power wise I honestly could use some guidance on a configuration/combination that would make sense including cam and type of carburetor (if my mechanical 650 1450 double pumper mech adv isn't ideal) what cam and converter. Stroke de-stroke leave stroke etc.
Stroke/destroke… whoa, hood on a second. Let’s not put the bourse before the cart a second. Normal thinking of the more concerned around here will ask this; Are you prepared to though bags of money at this engine build?
As noted above, a wise man did say an inexpensive route is a junk yard 5.9 Magnum. I did this in my ‘79 Dodge Magnum. I added 1-3/4 headers from Hooker, which fit your car, a Edelbrock RPM-AG and a 750 AFB. (Also due to the year of the car and not a bad option for yourself ether is an) added upgraded ignition. My trans is a 727 and the 9-1/4 rear has 3.55’s on 245/60/15’s.
The engine combo is a known 300HP combo if not a tick more power. The Magnum is a little heavy at just under 3600lbs. It has all the creature comforts minus T tops or moon roof.
All in all it is a good street performer and a excellent driver.
At a minimum it sounds like the M1 wouldn’t be all that great 1500-2500 RPM where the around town cruise speeds would be used often.
In order to get the single plane to act nicely on the street, it will normally need a high gear ratio and a reasonable converter to match the camshaft. It can be done, but, most people ***** about it.
