I can't find this test on the website. If I could see graphs of the torque curves, it would really help.Since your tests used a camshaft with .100 more lift than anybody I know of would use in a STREET engine, how would a more realistic cam selection affect the torque and power numbers? Also, an idea of what the results on an 350-inch engine would be, would also be REALLY nice. Which intake had the best torque at speeds BELOW 3,000 rpm?I can see you guys are (mostly) a drag-racing magazine, but guys, can we talk REALITY here for a minute?The reason I am asking: I have an '85 Buick LeSabre wagon that I want to tow with. I may want to pull as much as 4,000 pounds. It has a 350 Goodwrench engine, an Edelbrock 2101 Performer intake with Quadrajet, and an HEI. The beast is 4450 pounds, has a Turbo 350 with a big cooler, a 2.73 rearend, 28.5 inch tires, and an aluminum radiator. I would like it to get reasonable gas mileage, and have enough torque to pull any of the mountain passes out West. (I live in Atlanta.) I and the car are old enough that it does NOT need to meet emission tests.)The Goodwrench engine has an odd issue: the valve covers don't seal worth C$#P because their sealing surface is NOT machined. It is rough cast iron. I have NEVER seen no *** like that before! They leak oil like crazy!!The previous engine was a 355, with World Products Stock Replacement 67-cc heads, and the Edelbrock Performer-Plus cam. (.420/.442, 270/280 degrees). I still have the engine. In this barge, with the tall gears, the cam actually felt a little "big". From 0-25 mph, it was OK but slow. From 25-50 mph in Low gear, it pulled hard, did a snap shift to 2nd, and pulled hard to 80-85 mph, did the shift to High, and kept pulling. I have a Quick Fuel 750 cfm Slayer to try on it next, also Hedman shorty headers. Would the Edelbrock EPS or the Peformer RPM, or the Performer Air-Gap give me the best results? For my towing requirements, should I : Use the World Products heads? What about enlarging the exhaust valve pockets? I hear that is worthwhile. Build a 383 or 391 out of the old 355? Maybe Comp's smallest 4X4 cam would help. Change the rearend gear? Do I need better axles? Posi would be nice. I am thinking rear discs & upgrade the front calipers to SSBC. Heave-ho the smallblock & put in a 454? THAT would fix the torque problem for sure, but what about the gas cost? Would I need a Turbo 400? I don't want the expense of a 4-speed auto, and had awful luck with the Turbo 700-R4 in a '92 Olds wagon.
