    Oil gallery plug size?

    Can somebody tell me the correct size or part number for the plug that goes inbetween the oil filter passages under the #5 cap? Apparently I threw the old one out when I tore this engine down, or just can't find it amongst all my junk. Thanks!

    Working on a friends car and noticed what looks like five tiny holes drilled from underneath. There are raised ridges around them. This is only on one rocker. Why?

    Re-using Felpro 1008 head gaskets?

    Would you? Have you? Your experiences? I pulled one head just to check the gasket. Turns out it was an intake gasket that failed to seal. The head gasket looks fine to me. The head gasket got coolant on it when I pulled the head, but was immediately wiped off. This gasket was brand new 400...

    How bad?

    Ran the car at the track Friday. No issues. Drove the car Sunday and all was good. No smoke, no overheating, nada. It was 28° here last night , but warmed up today. Went to crank it an hour ago and it didn't want to. Acted like the starter was stuck. Finally cranks and after running for a few I...

    Tired of DIY!

    Obviously I suck at sorting out this small block stroker! Really just want to send it out to someone who can make it run like it should and not leak a drop of anything. Spent a week putting it back together after head porting, in Texas 110` heat, only to have it leave puddles and run worse than...

    Mr Gasket 1121G with aluminum heads?

    Debating these, or another set of 1008's. 1008's were pushing, probably because of not being torqued properly, or not getting re-torqued. Interval for re-torquing with 1008's and/or 1121's, if I should even try them? Heads and decks will be checked first.

    Camshaft degree equipment?

    Just want to know what you guys, especially you pro's prefer. I am looking for a good 'heads on' setup. Somewhat reluctant to buy a kit, as I have most of the components, but my dial indicator base is not working very well for me.

    Cam plug leaking. Removal and replacement?

    Got my engine out to get heads ported and finally locate an annoying leak. Expected to find the rear main seal or rear of the oil pan leaking, but instead I found the cam plug was actively dripping, even from just tipping the engine. Is there anything more to replacing it than carefully tapping...

    Got a friend with one in front of a 904. External balanced engine, right? What flex plate? Balancer? Can he run a neutral convertor? Where to weld weights? (If applicable) Never messed with one, and trying to help him get the car on the road.

    Mr Gasket 1121g torque and sequence?

    Throwing together a 318 for my truck. It's a 68 .040 over 318 with 4027163 heads with smog ports plugged. Pistons are .040 down so I am using the thin gaskets. Block and heads are not milled that I know of, so I am aware it's a gamble, but the truck is a back burner project and I have a set of...

    Took it to the track- cutting out at 5k!

    Seems like it was losing fuel, dying out 3-4 times at about 4500-5000 then coming on strong in 3rd gear. Also died a couple times after hard braking for track exit. Edelbrock 800 cfm...ideas? 6902 Carter pump, wondering if it's excessive fuel pressure, OR a lean condition...open to input.

    Blueprint Engines Crate Motor?

    I have a friend considering a crate motor from them. He called and emailed asking specifics about parts used and they couldn't seem to tell him much.

    Smoke and miss at startup!

    Even sitting a couple hours, I'm getting a rough idle and smoke on startup. Once I gas it for a minute and rev it a few times, all is normal and good with plenty of power and normal idle. Smoke is not really black or white, kinda dark gray. I'm thinking valve stem seal leaking, but wanted to...

    Problem with Comp Pro Magnum adjusters.

    Please tell me about 80-84 318 cop car engines.

    Made a new Mopar friend today with a 65 Dart. He has what he was told was a cop motor, casting # 4104230 with 587 heads on it. Are the heads correct? What pistons would be in it? Compression ratio? Want to get him signed up, clued in, and help him out. Any info is much appreciated, the history...

    Tell me about these heads - 2658920 66-67 273-318ci

    Any info or good sources for info? Are these originally closed chamber? Can anyone tell by the pics if someone added hardened seats? Thinking about using these on a 318 I would put in a 85 truck. Thanks!

    Symptoms of an Intake Leak?

    Still fighting cooling issues, but everytime I set the idle and drive the car more than a few miles, the idle jumps up a couple hundred rpm's. My theory is my intake is leaking slightly and when hot the metal is expanding to seal or reduce the leak. The vacuum guage needle is shaky and bounces...
