Compression Ratio
Stock 318 with bolt ons for cheap? Here's my result : 72 Duster . Stock 78,000 mile 318 . Summit 272 454 cam and lifters I got for $100 on Black Friday. $20 replacement timing set . Yanked the heads and did a quickie bowl blend, Comp 901 springs and new valve seals. LD4B intake and 650 DP. Dougs headers with 2.5 exhaust. 3.23 gears. Went 14.39 at 96 with stock converter on Cooper Cobras. Installed a PTC 3500 converter and M/T ET Streets and went 13.89 at 97. I only have nine passes on it with no real tuning so far. This was supposed to be a temporary engine until I build a 360 (or 408) but it may be in there for awhile.
