I used this cam in a 318 in my old 71 Dart. Absolutely loved it. Had a little bit of a lope to it in the 318. Motor had a Edelbrock Performer intake, headers, and a Holley 650 doublepumper w/1inch 4hole spacer. My compression came in however at a measly 7.9:1!!!
Car ran 8.90's all day in the 1/8 and I could drive it anywhere. As a matter of fact i drove it to the strip every time. And got around 12-15mpg with it. I was complimented at the track when after seeing it run, guys would come up and ask if it was a 340 and they were shocked when I told them it was 318.
Actually, I bought the same cam for my new 318 build for my Valiant. Except I'm going to run the small valve J heads and have around 9-9.5:1 compression this time around. Will also be using 273 adjustable rockers as well.
I'll use the same size carb and have a Performer intake. Oh, and the teen is getting bored .030". The last one was a standard bore. This one ought to run like a champ.
I think you'll like it. I installed it straight up.
