    Lubricate cam bearing od at install

    Hi everyone, doing some research as I'm installing new cam bearings on my 400 stroker. The question i have, is who is lubing the cam bearing outside diameter before installing? It feels like the bearings being oversized to achieve a press fit, it shouldn't matter? The input I've read almost...

    Comp Cams not responding

    I had actually forgot about it, but a few months back I too had tried their online recommendation form and never heard back. I received an email stating they received it and would be reviewing, but never a response. I was just toying with some numbers so it didn't hold me up on anything, but I...

    I run their 400 block .030 over for 499 ci kit and have had zero issues. The balance is right on nice and smooth. That combo is in my Challenger and have driven back and forth to Carlisle from Cleveland no problem and get to the track a couple of times a year or simple TnT stuff. Just did a comp...

    Who are my 400 stroker guys?

    Yeah I'd think if you work the suspension/hook out you could do it. My junk is all factory rear and I've done little to help myself there. My 60 ft were garbage, and a good build and honestly a good dyno tune would improve alot.

    Who are my 400 stroker guys?

    I have a .035 over 400 using the 440 Source 500 ci kit. The block wasn't decked, and the pistons sit in the hole about .030" I'm using the -4 flat top pistons and topped with closed chamber fully assembled Eddy RPM heads. The cam is a solid Lunati that is the most aggressive Voodoo. For my...

    400 Build vs 440 Build

    I too run a Holley Dom that I had found on E-bay. Enough cubes that on the street the single plane is not a problem. I also have an 850 DP on it and wish I had a bigger carb to try on it, I get the feeling it would like it in a strip setting.

    400 Build vs 440 Build

    I've got a 400 with the 440 Source 499 kit and love it. As a cautionary tale keep in mind the increased stroke and bore will cause a high comp ratio without any other changes. Get the dished pistons and even with closed chamber heads you will be OK, just food for thought if pump gas is your...

    BB Gear Ratios

    My A833 in my Challenger is ahead of my 3:55 rear and wouldn't like to go any steeper and do freeway driving.

    Tuning with jets, Power valves and an O2 guage

    Boy that's a bummer, I wouldn't try a thicker head gasket, as you say your at about .056" on quench and don't want to get carried away. 190 psi is up there for pump gas engine ( I know, you know that ) Yeah, guys have made it work, with fuel injection, spot on quench, polished components, yada...

    Tuning with jets, Power valves and an O2 guage

    I would have to guess you can't get 93 octane ( that's what I use and can get easily here ) and your stuck with 91. If you had to guesstimate your cranking pressure where are you p.s.i. wise? Did you talk over build/selection with a builder/Lunati? Are your Eddy's closed or open chamber? Are you...

    Tuning with jets, Power valves and an O2 guage

    The old saying is every engine is different, and yeah you will begin to slow the starter at some point, BUT I have even locked the timing out at full advance once and was able to crank over hot. Sounds to me that you must be close, I like to look at vacuum & RPM ( when it stops climbing with...

    Tuning with jets, Power valves and an O2 guage

    I have a 499 stroked/bored 400 with similar cam. I run an Holley 850 DP, and yes that combo wants fuel. I too opted to run a wideband and after reading some articles about some engines can idle/transition well as lean as 14:1 there is no way with a carb setup that's going to happen. I now idle...
