Headers vs 340 manifolds
Reading this again since I posted this question 2 years ago
Completely stock 340. 4 speed car 3:23 gears non sure grip
Thinking about long tube headers vs stock 340 manifolds.
Car will be tuned if header installation moves forward.
Realistically, how much gain can I expect?
No other modifications planned.
Asking all the Mopar experts on here.
