Hi All, I've got some basic questions I can't really find the answers to. Not a lot of people use the 400 engines, and almost every post I can find about this engine is people saying "up the compression". I agree, the late 400 engines have shitty low compression. But it's what I have and I don't have the money to play with higher compression ratios. And these engines can still be a lot of fun. And remember, I'm from the country where people drive 60ci cars with not a lot of horsepower. To answer the first to be asked questions: I've send multiple Cam manufacturers a message, but I want to hear some experiences. This is a cheap/budget build. No I'm not taking the heads off to up the compression. No I'm not replacing the heads. I've got a '77 Chrysler 400 engine for in my '68 Newport. (original 383 too expensive to fix at the moment). I'm thinking of swapping the camshaft before the engine goes in. Not looking for a lot of power, just for a bit more than stock. I'm just not sure if it's worth it with this engine. Thumpr/Whiplash cams are always advised for low compression engines, but I don't think I can get away with one. I have power brakes and I'm planning to keep them! Some specs: - stock 1977 400 engine - 135-150PSI on all holes - edelbrock DP4B intake with rebuild edelbrock 1406 600CFM carb - New electronic ignition system (distributor, coil, leads, box etc) - Hedman 78070 short headers - Dual 2.5" exhaust - 2300-2400RPM stall converter - 3.23 rear gear - Power brakes Is it at all worth it to swap out the stock cam in this engine? It has 452 heads on it. What is the max lift (on average) on these heads? Can you always get away with .480-.500 lift or it that already cutting it close? Sorry for another cam thread. I'm really looking for experiences.
