Shorty Headers

Has anyone out there tried the new Edelbrock shorty headers? Do they really flow better than the stock manifolds? I'm thinking about getting a set, but would like to know if it's going to be worth the money. I've always used full-length, but on my latest project, I want to give these a try - mainly because of clearance issues, not cooking my starter, and ease of installation/connection to existing exhaust. Will it just look nicer and not have any better performance? I'm thinking of these for a Matador Coupe with a 401 engine. The engine is not stock, but is close. Air Gap intake, Edelbrock 750 carb, Comp Cams XE262H cam and kit, otherwise stock but freshened up very recently.

Thanks

Try a 190 or 195 degree thermostat. It won't make the engine run any hotter as in reducing overheating, it just lets the engine get up to operating temp faster. As Tom J suggested, check the timing.

I found oout the hard way that to much antifreeze is a bad thing! I had about 60% AF and 40% water in my stroked six (4.0L, now 4.6L). It would run hotter than it should on warm days, and boiled over a couple times before I figured out the cause. 50-50 is max recommended unless in really cold climates -- I was on the Mississippi gulf coast -- really hot and humid in July and August! Drained and started over from scratch -- no more overheating even on 90+ degree, 85%+ humidity days.

I heard on the news report here in Dover (Delaware) that there was going to be "oppressive humidity of 72% along with mid 80 degree temperatures" and couldn't help but laugh! That's a typical late spring/early summer day in MS, might even be a bit low in humidity!!

Thanks for the info!
Well, I am running a M&M Supercooler trans cooler mounted ahead of the A/C condenser. There is an air gap of about 2 inches between the cooler and the condenser. I do suspect I may have a bit too much antifreeze concentration. I am thinking about draining about a half-gallon, replace the 160 thermostat with a 180, replacing the coolant drained with another bottle of water wetter and pure water.
