65 Barracuda 318 Rebuild, Cam, timing, lifters maybe a kit?
from the 318 build article
- 331 HP at 5750 RPM:
- Swapped the 360 heads for ported and polished 302 heads modified with 1.88" intake/1.60" exhaust valves
- Mopar Performance P4120249 valve springs
- This combo produced a 41 HP increase over the previous combination, netting 1.12 HP per cubic inch!
- This combo also produced more power than all of the other combinations from the lowest RPM on up"
- my comments
- I agree that 915 X J heads may make more top end power above say 3500-4000 so what for a street car with stock gears and converter
- the X J combo would take a longer duration cam to do it which would kill the bottom end
- Velocity wins here IDK about the Edelbrocks LAX EQ or other heads- where they fit in
- they would obviously be winners in the 3500 up area but around town?
- Anyone have an inexpensive CNC program for the 302 I still have access to my old SERDI so I can DIY-otherwise take your time and do it by hand
- OPEN CHAMBER HEADS are losers (without high octane gas and high revs)
- toolman A semi ported 302 may well outpower a semi ported X or J or 915 even looking at the graph anyone check Stan Weiss site yet?
