My car had the 140 cam since about 1970, guy installed it and springs with aluminum retainers. Retainers were prone to cracking so its a wonder I have original engine. My car had 4.88s but just took them out. Not much fun on freeway. Mine likes 1000 also. I would think your compression would be a big help.
Hakan, Anymore they have decided that nasty idle isn't needed to make horsepower. I had a 383 built with dart products parts and it has a somewhat small roller in it. My 472 hemi has a small roller in it and its making right at 600 horse at 6000 rpm. Just over 10:1 in pump gas. It idles about 900 and is very calm. I have a dyno and exhaust sound video on You tube under bill foos if you want to hear it. Rollers are great with the oil we have now too
