Well.... put her all back together and she ran super strong. And then she didn't. It's looking like either my lifter has collapsed or my cam lobe has gone flat on my Cylinder 4 exhaust valve for no good god damn reason. the rocker came loose twice and now I'm having to screw the nut all the way...

So things I've learned.... 1) do not use coppercoat or any additional sealants when using newer Fel-pro head gaskets with permatorque coating. It caused leaks between almost all my cylinders in less than a year.  2) Fel-pro Printo-seal intake manifold gaskets SUCK.  The seal around 3 out of my...

Got them out with some torch to the pedestal!   Does anyone have an intake manifold gasket they swear by? I got the same type (Fel-pro 1240) and am hoping with Don's torque specs and absence of Silicone they will do better this time.  Also, looks like my head Gaskets were leaking between my...

Taking off the heads today. The intake manifold gasket looked cracked! Might have happen during removal though. Had some over heating and coolant loss so re-doing the head gaskets and taking the heads to a engine shop to make sure there are no cracks etc... BUT...   Now I can’t get my screw in...

Going to order a fresh intake gasket and torque to your specs Don.  Thanks Tommy, I'll try backing out my idle mix screws a half turn and see how that goes. the only rebuttal I may have to the idle circuit being too lean due to high vacuum is my idle vacuum is only 9-10 inches/mercury   My...

The cam specs listed in the original post are the advertised specs. I've checked extensively for vacuum leaks with carb cleaner and plugging, so I'm confident there are none unless it's under the intake and figured it would have been done to damage during installation. I'm using an electronic...

I've taken apart and cleaned the carb a ton. I've shot brake cleaner through all the passages and none seem obstructed. It's definitely been running lean, I'll cruise for 5 minutes through out the trouble rpm range and shut off the engine, stop and then read the plugs and they either look new or...

Hey guys,  Always like to start by thanking the community for its invaluable help and expertise, so thanks :)  So... I haven't been able to figure out this issue since I put in my new cam and went from a 2bbl to a 4bbl carb.  My engine struggles between around 1000 and 2000 RPM. Seems to clear...

The backfires were before I tuned the mixture screws and timed it, so I wouldn’t count that on the list of symptoms. And yeaaaa I've been thinking I oshould tear it down and put it back together to make sure, just been procrastinating since its my daily driver. Thanks

So if I'm accelerating from a stop, or cruising real slowly, from 1000-1500 RPM it does what really seems to me is like a rich blurble and runs rough. (I'm going to pull some plugs to check color) Then at 1500 or shortly after it smooths out in one immediate moment with a boost of power. I'm...

Hey guys, went out of town for a little while but finally got back to the car and figured out the surging issue. It was a bad PCV valve. Should have figured it out, but it seemed to go in and out. got it timed precisely too. 12 degrees initial, 35 degrees total. My vacuum gauge method had...

Thanks guys. Right now I had the mixture screws set at 1.25 turns out each. I did this using my vaccine gauge. I took them between 1 and 2 turns before and there was no impact, however I did all of this in park while the surging is less noticeable. The idle screw is almost all the way out...

I have the Summit 850306 ready to run distributor(4 years old),  a brand new QuickFuel slayer 600vs 4bbl carb and an msd flamethrower 2 coil(no idea how old). I had a loose coil wire for a while, don’t know if the intermittent connection could have damaged anything over time.  Any tips on a...

Thanks that will be helpful! Glad you think the vacuum sounds normal (between 14&15) I thought I should be closer to 20. Re-did the choke and mixture screws when it was hot. Didn’t change much. Will have to dial in the timing precisely when I get back into town. From fiddling with it...

ALRIGHT! Whew what a crazy couple of weeks, sorry for the radio silence, but I was tending to it all . Aside from all the mishaps along the way, I crashed my motorcycle and broke my foot. But got her all put back together now. Thanks for the advice everyone, might need a little more. For the...
