LA 340 Intake Manifold
The wife’s car is a .030 overbored 360 roller block (not a Magnum block) stuffed with Federal Mougal/Speed Pro Hyperutecic C116HP pistons set at zero deck. (Zero deck need not be)
The cam is a Hyd. roller (actual type of lifter is your call) with the specs pictured below.
It has a 750 cfm carb (recommended!) RPM-AG, Trickflow cylinder heads, 1.6 rockers, TTI headers and exhaust and a MSD - RTR distributor. (You’ll need to go to 4secondsflat.com for timing bushings to get it where it needs to be)
The converter is the OEM odd splines unit (which is a huge problem since there’s zero aftermarket support) which was custom stalled at ProTorque for the car. The car runs 3.55’s on 26 X 10 Mickey’s.
While this is not a fast off the line combination, it does run really well and has a good long top end pull. Frying tires is not a problem and I can do it for days.
I used to notch parts for a no nonsense approach and best results for the parts used as cast and OOTB. The use of the 1.6 rockers on the Hydraulic roller and cylinder head combination allow this to rev a little beyond the cams listed rpm range. I haven’t found top end speed yet. I threw in the towel at 130 mph with about a 1,000 rpm left in it.
I re quoted you for a reason. Allow me to tell you about my wife’s car, a ‘67 Cúda. While it weighs a good bit less, this may be of use to you. In a FWIW, IF the car was mine and I was constructing it with your above guide lines as my goal, this is what I would do myself.
