Disappointing dyno results

jawbone said
Hi dartfreak75. Thanks for the inquiry. So much time and effort went into this build I am truly depressed with the results. At the moment have lost all momentum to continue. I am a very detailed person by nature. It's not that it's difficult to disassemble the engine; quite easy. It's the degree of perfection that went into putting it together. The pistons are JE brand .030 over. Know nothing regarding rods other than not stock. Assembly was balanced. Big valve "O" heads all stock. Cylinder pressure test = 150-160 psi. Was building a driver but at least expected to get stock performance. Would truly appreciate help in selecting a cam. Contacted Oregon Cam Grinding regarding replacement. There is word they have specs for 68 340 4 speed cam. They don't but reported people happy with approximate duplicate. If I do this means I have to drag engine back inside office including engine hoist and stand. Prep is a killer.

I understand your frustration and loss of momentum! Trust me I get it more than most! I ran into issues with dang near every step on mine and had to reconfigure my build several times. At one point I got so frustrated and overwhelmed it wasn't even fun anymore and walked away for almost a year! Then got right back at it and solved the issue in no time. When I say we are here to help I mean that! There is so many helpful and knowledgeable guys here that know by doing not just know by reading or youtube lol. I'm quite partial but I would really recommend a luniti voodoo 10200702 cam. I understand you not wanting to tear it back down I really get that. If it was mine I wouldn't want to either. I would probably slap it in the car and drive it and see what the car does. It may run better than you think and you will be happy with it. If it's a lazy slug and you can't stand to drive it because it's so boring you can swap the cam from inside the car.
