    SBC 355 Pressure Under Valve Covers???

    Fresh rebuilt motor with less than 100 miles on it. My issue is this- what would be causing pressure under the valve covers? At idle there seems to be no pressure, but once rpms raise up the pressure increases and pushes oil past grommets and out the breather cap. Could a valve be staying open...

    SBC Centerbolt Valve Covers

    Where at? Then I would just drill an appropriate hole into the new covers. If that would work of course. Sent from my iPhone using Tapatalk

    SBC Centerbolt Valve Covers

    Okay, first things first. I’m at wits end searching. I need a set of Centerbolt (Vortec style) valve covers with a breather hole and baffle. I want fabricated covers. There’s plenty of people to make them without a breather hole but I need one. Any help is appreciated. Sent from my iPhone...

    I do have a tach. Running 65 it’s at 2500. Sent from my iPhone using Tapatalk

    700R4 and Correct Gearing

    Nope. Did some further digging and this torque converter is does not lock up. The plug going to the tranny doesn’t have power anyways. Sent from my iPhone using Tapatalk

    700R4 and Correct Gearing

    I bought it used and it had this written on the side of the bellhousing. “4x4-Kevlar Clutches-Shift Kit-Fresh Rebuild-B&M Pan”. I even swapped the old governor from my busted trans that was previously built and it didn’t really change much. Sent from my iPhone using Tapatalk

    700R4 and Correct Gearing

    I didn’t swap converters. Was nervous about there being trash in it from when the trans housing cracked. Sent from my iPhone using Tapatalk

    Perfectly fine with original trans. Sadly it’s sitting under the shop with a cracked housing. Sent from my iPhone using Tapatalk

    700R4 and Correct Gearing

    You are right.....to an extent. It shifts down correctly, then back up but doesn’t want to turn more than 4K. Full pedal in OD is 4K Sent from my iPhone using Tapatalk

    700R4 and Correct Gearing

    Let me rack your mind on this then. What would keep it from wanting to rev over 4K at WOT 4-2? In neutral, the motor revs great and so forth in 1st or 2nd. But when you want to “pass” someone it doesn’t want to rev more than 4K. Sent from my iPhone using Tapatalk

    700R4 and Correct Gearing

    It seems to be all coming now that this different trans is in it. Never had issues before with rpms. I have heard that 700R4s don’t go well with low gears though. That’s my concern. Do I need to raise the ratio? Sent from my iPhone using Tapatalk

    700R4 and Correct Gearing

    It’s just aggravating me that I have almost 500hp to work with and when I open it to WOT for a 4-2 shift, it feels like it’s held back extremely. Sent from my iPhone using Tapatalk

    700R4 and Correct Gearing

    After the failure from the previous trans that was built for the motor I bought this one used. The lockup doesn’t seem to be working in my opinion. It has a Fairbanks torque converter. Not even sure on stall rpm. Motor specs-5.7 Vortec block, aluminum lt1 heads, .40 over, Lunati roller cam. It’s...

    700R4 and Correct Gearing

    I need some tranny and gearing gurus to chime in as much as possible. Going to try and keep this short and to the point. Specs are this -84 K10, right at 500hp 5.7, NP208, and 700R4. I had originally had someone build a 700R4 setup for this motor yet, had some driveline issues and busted the...

    700r4/NP208C with 4:88 Gears

    It’s a strongly built 350, and the rpms seem to put it in a great position of power as far as ready to pass or get on it. Just been contemplating on dropping down to 4:10s since it’s more of a street truck/weekend cruiser. Sent from my iPhone using Tapatalk

    700r4/NP208C with 4:88 Gears

    Truck used to have 37s. Went to 33s on my weld wheels. I’ve heard that low gears and 700r4 trannys don’t get along. Other than high rpms in overdrive, don’t seem to have any issues. Any input? Sent from my iPhone using Tapatalk

    84 K10 throttle cable

    Throttle cable seems to have slack and not pulling the carb to WOT. Doesn’t seem to have a way to adjust from the firewall to carb link. Is there another way to adjust or anyone have any ideas? Or should I look into an aftermarket one? Thanks in advance! Sent from my iPhone using Tapatalk

    So I’ll be looking into ordering new shackles I guess. The driver side doesn’t seem like it’s pivoting with the spring. Sent from my iPhone using Tapatalk
