I've been shopping around for a performance cam. I've seen some comp cam kits on eBay. I'm looking for something quite a bit more lively than stock, but not sure which one to go with. I've heard Erson is pretty good as well...Any recommendations or opinions?

Sure, use your stock cam and have it reground to fit the requirements of your particular needs.

Example:
I was in search of increasing torque and mileage. I drive a 120 miles a day and was looking to reduce my monthly gas bill. Doctor Dodge and others suggested that I have my cam reground to the specs listed below. The regrind cost me $35 at Delta Cams in Tacoma, Washington.

Unexpected benefits:
With the amount of material removed from the head and block, the reground cam allowed me to use my old stock length push rods. I now have a compression ratio of 9.5. Mileage has gone from 18 to 22-24 mpg depending on how much self control I apply. It is very tempting to light'em up now and then and/or pass every Mustang GT that gets in my way. I have yet to take a trip to find out what the mileage might be. Most of my driving is city, stop and go mixed with freeway stop and go....... It rarely ever gets up to 3000 rpm. From 650 rpm to 3000 I have alot of punch and overall pep!

Use your search function to go to the" Erson group cam buy" in the engine section and read the whole thread for some really GREAT info on cams. There are some NEW patterns that show real improvement over "standard" grinds. If you have further questions then ask.

Lets not get carried way now. I can pass a Mustang GT with my moped if my compention doesn't stand on it.

your cam and CR specs, along with your rear end ratio, doesn't make much sense to me for that MPG figures... can you elaborate on how do you drive those 120 miles/day ? that 254 duration is seat to seat? I'm kinda stumped... see, 24 mpg with a torque cam mated to a low numerical rear end ratio and an economaster makes sense to me, but then you throw in the "passing mustangs GT" line and that doesn't allow me to see the whole picture.

I found that EGGE Obsolete engine parts carry slant cams that sound interesting. .435 lift 212 @ .050 and lobe sep 105/115 or something like that. Want bigger? Erson # E470521 lift .510 in 242 ex246 degrees at .050 and lobe sep at 108

Bren,

I don't think the Moped would have a chance here in the northwest on the twisty two lane road that I travel along the foothills to get to our local freeway, I-90 to Seattle. That is where I do the passing which is very limited in straight-away before there is a bend or hill. I have had a few GT's give me a run but I can get up to 90 mph pretty quick and blow by them.

Mind you that this is not like my 375 HP 440 cars but the SL6 is no slouch either! For a one-barrel it is doing extremely well and is allot of fun to drive.

I would imagine I would be allot quicker with a 4 barrel. I just found a Weiand four barrel manifold for the SL6 that I will try next year. Also picked up a aluminum one barrel manifold to try this winter for more heat! It is freezing up here!!!!
We are suppose to get more snow today......

very nice to hear your input, Ted, sorry if I came out sounding "pissy" or "aggressive", not my intention, nor to call you a liar, just had an insane curiosity about the hows, the what and the whos, and you're provided me (and the board members) with excellent information. I have yet to see an economaster in person (never got those here) but heard some good things about them. Your setup is very nice and I bought from the beginning the "passing mustangs GT" line but had my share of doubts about mileage when doing so It's a VERY promissing setup for the everyday driver. A properly tuned 1 barrel carb would be every bit as good if not better than a (big) 2 barrels. The only thing that I like better than a good holley 1 barrel is a jap staged small 2 barrel carb such as the solex licensed mikuni carbs on galants from the late '70s or the AISAN (from celicas of the same period) but those are complex carbs.
