Got ahold of a degree wheel and checked the ICL twice today and got 107.5 both times. Cam card calls for 106 and I'm already in the 4 degree advanced keyway in my timing set.

Should I buy a new crank key and advance it more?

I would put it in at 101 or 102.

I would leave the cam.... Is your fuel getting hot from anywhere? Did you check your timing mark on tour damper?

Fuel is a 1/2in line return system and the closest it get to any heat source is ~6in away at the mufflers so it shouldn't be getting hot. Ive never checked, but the balancer is new. I'm going to put a decal on it when it goes back together.

I'm starting to think the cam is a little rowdy for the rest of the combo.

That is a big cam......... you will need a real loose converter... is it an 8 inch?

what is the convertor stall and what gears are you running? cam card says 3000 recommended and I would run a 391/410 gear. 107.5 isn't a big deal but I personally would retard it 2 degrees.

3.91 gear and what should be a 3500-3600 stall 9" PTC converter. It's never ran well enough to test the converter. 325 drag radial (28in) tire

I'm going to throw a 4 degree cam key at it and put a new tape on the balancer. I may get one more weekend before it gets cold.

I'm not that big on advancing cams much. But in your case it is the cheapest fix. A cam with 10deg less duration on the intake would work better in straight up.

Its just my opinion but I dont think the cam is all that big. Bullet made me a custom 251/255 for my stock stroke 360 and the car is heavy with the same compression as the op's. But every time ive had a cam made for a stock stroke combo the cam grinder always told me to advance it..and not one time was it over 104. Op would be doing himself a favor to call the cam company himself and get their opinion.

Hot It really depends on the converter in this case...... Problem when asking the cam company is....are talking to someone who even has a clue... You need to find someone good at specing cams.. You find the people leading in this area are not advancing the cams like was once done.... But in this case, he should advance the cam if all else fails......

Both cam companies were Cam Motion and Bullet, and they are well respected..and their advice is recent. But I agree the converter is an issue. But all the more reason I would advance it. If I paid for a 9 inch converter that only flashed 3k, it would be back in the mail. hopefully the op can get it figured out enough to really test the converter as well.

Bigger issue is the 0" vacuum at idle and the puffing out the breathers. That cam is not that big and should pull around 6" at least at a 850 rpm idle. I would fix that up before I spend $600 on a converter. Make sure your balancer is at 0 at TDC. Then add the timing tape, set initial at 18 to 20 degrees then make sure your primary throttle blades are not open to far allowing fuel to dribble out of the boosters at idle

I also got a new vacuum gauge this past weekend I I will take another reading once it's all back together. I'll also get some video of the breathers puffing. Hopefully the rings just haven't seated well because it was running so bad

Thanks guys

Cam is in at 101.5 and she runs great! 6-7in of vacuum at idle now. It also really like the increased timing at idle. 55 degree day and she fired right up after sitting for 2 weeks, something it has never done.

Only problem I had was a rubber muffler hanger that broke on the test drive . I got it off the road and pulled the muffler off and drove it home.

Thanks dudes.

Glad to hear you got it running closer to your expectations.
