OK
trick flows have flows at lifts you will never use way too much for a 318 unless you are building a bracket trailer queen and less flow under .500 than ported iron or Magnum heads
Air gap goes with the trick flows, not in the rpm for a street SW
That cam suggestion borders on ridiculous- see bracket racer above
He would be better off with a STOCK 9.2:1 318
256 cam say 460 lift
dual plane manifold anything but an Air Gap
600 cfm Vac sec carb
no rockers unless he wants to buy the B3 kit and custom pushrods an d even there not worth the money
he needs torque 2000-4500
FORGET HORSEPOWER give up 50 HP and gain 50 ft lbs of torque
or box stock motor with a blower spring for a new timing chain what 67gt just said
another solution is a roller 360 or take out Magnum 360 and tell people it's a 318
FORGET HORSEPOWER give up 50 HP and gain 50 ft lbs of torque
Great to the point advice.
This is EXACTLY what your friend needs to do if you must keep the 318.
It seems that the whole purpose of this build would be for bragging rights and sound rather than practical engine building for the intended purpose as stated in the O.P.
Being a big fan of '69 Coronets, I have had several of them over the years (and still have a few of them).
I have driven stock 318 automatic 4 doors for many thousands of miles over the years and loved them.
They are a great combination of looks, modest power, and driveability.
I also had a '69 Super Bee with a 440 4 speed 3:54 Dana rear end, and a '69 Coronet R/T with the same combo.
They are a whole different animal as to be expected from a 318 '69 Coronet 4 door (or Wagon).
You asked for suggestions in the O.P. and changed the game later on to say that this would be a 318 build only.
That is why I stated that the post by Wymrider is your best bet now that strokers and big blocks are out of the picture.
Love the Challenger video BTW and thanks for posting it!
Good luck, and let us know how this turn out..........
