Chalk it up to inexperience. I wanted something with a nice lope to it. This has one. I didn't build a race car. Just wanted a cruiser with a little more sack than your average Cbody! The issue I'm am having is that even with a lil brake torquing it still won't spin em. Seems to me that it should have more power than the 318/904 2 bbl with the same 2.76 year gear. The 318 brake torque just fine. I'm working on eliminating the issue as I can!
That was my thought on it too. I did a bit research on the cam after my friend recommended it and went for it. But this being my 1st engine build maybe I did something wrong, who knows. I've been turning wrenches for a long time but was never an engine builder! I'll get it figure out as soon as the rest of life calms down a bit.
That's what I pulled outta that engine! Yea want it?? Lol
The 650 carb is in my opinion is a bad combo for the cam you're running. That cam was designed to increase your engines ability to breath but your restricting the engine by running a small carb. A 750 would be more suitable. Last but not least you need a bigger gear. The biggest mistake that first time engine builders run into is the notion that more horsepower = being thrown back in your seat and suffering sever whiplash when you stomp on the accelerator which more times than not will result in the exact opposite. Instead you end up with a car that is extremely sluggish and can't get out of its own way. When you increase your engines ability to breath by porting heads installing bigger cams ,bigger carbs high rise intakes ect ... you are increasing torque and horsepower. On the flip side by increasing your engines breathing capabilities you are causing your engine vacuum or what is also known as manifold pressure to drop off at idle and under moderate to heavy acceleration. Manifold pressure is necessary for the fuel entering your combustion chamber to atomize properly and is also required to draw fuel from your carb. Low vacuum = poor combustion efficiency and lean air fuel ratios under heavy acceleration. Some carb tuning such as jetting it slightly richer changing power valves and increasing the accelerator pump stroke will to a certain extent remedy the problem But ultimately you need a higher rear end gear and more stall to compensate for the low RPM power losses you will experience from a big cam. If you want your car to run right you either have to run a smaller cam or run a higher gear ratio. I don't claim to be an expert just speaking from personal experience and I had to learn the hard way myself. Sorry to hear of your family issues hope things work out for the best
