Hello all,
I was getting ready to install the roller rocker arm kit and measure for a set of pushrods when I thought of something.
If I order the pushrods and install them on the 440/493, they won't work if I decide to go with a solid flat tappet or a roller camshaft. Theres $200 wasted, right?
Here are the specs of my engine, for those that haven't read any of my other posts:
440 block, .030 over with a 4.15 stroke. Edelbrock RPM heads 84cc heads. Edelbrock Performer RPM intake, Demon 850 VS carb with 85/92 jets. TTI 2" headers 2 1/2" exhaust.
Calculated compression ratio of 10.73 to 1. 292/509 camshaft installed straight up. 160 thermostat.
727 with 9 3/4" converter, Gear Vendors OD, 3.91 gears.
I looked at a few websites and landed on the Hughes Engines site. They don't list any specs for their solid roller cams because they are supposed to be custom ground. Since I will be using the Mancini/Harland Sharp rocker arms, I could go with a solid or hydraulic roller. I'm not sure which way to go here. As stated elsewhere, this is not an all out race engine. I like to drive the car more than up and down a dragstrip. I've made 3 trips of around 1000 miles and intend to do more. Setting valve lash once or twice a year wouldn't bother me if there was a performance or durability gain to be had. In truth, I am not totally convinced that a roller cam is necessary. I have read about EDM lifters that provide better oiling between the lifters and lobes as well as the "Pro-Plasma" treatment offered by Comp cams.
My intended goals may sound far fetched to some, but I hope that they are attainable. I want to be able to run strong on pump gasoline in 40-100 degree weather. I want to be able to drive the car short and long distances and get reasonable fuel economy. I've seen 12.5 mpg with the current combo. If I lost a little of economy but gained power and had less or NO detonation, I'd be quite happy with that.
I've read in Andy Finkbieners book about 600 HP 500 inch engine builds. Am I knocking on the door of 500 or more HP with the right cam even with UNported heads?
If I decided to drag race the car, what range of ET and MPH could be expected in a 4000 lb B body with 3.91 gears? Is it possible to get into the 11s with a combo like mine?
