I've messed with timing settings dozens of times and nothing really improves performance significantly. Now timing is at about 15 degrees idle and goes up to around 32 degrees at 3,000 rpm.

I did recently adjust the carb mixture again with a richer mixture and seems to pick up a slight improvement. My guess is hp is on par to the 350 HO now which isnt too bad so I am not as disappointed as before but was really hoping to get at least a little more than that.

I'd guess the car probably does have around 320 horsepower like the HO but I have a very hard time seeing it have anywhere near 380 lb-ft of torque like the HO has.

The low end is what I would actually like to work on so I may order the Rhoads lifters that I recently learned about.


If I were to guess, I'd say this car might do around 14.5 secs in the quarter mile. I hope to test in a week or two and will report back.

Other than that, I am kinda hitting a wall with getting this 350 to excel better than the 350 HO. I am beginning to think that is the max possible performance and these engines really are duds

I assume when you degree the cam you used a degree and found true TDC and zeroed everything. Have you done the same thing with your timing marks, made sure they show zero at true TDC?
