    How much HP will a th350 handle? New motor!

    Have had the Blueprint 400 installed for over a year. Haven't put but 1k miles on it as it stays parked for the most part during the winter and I have other vehicles. https://www.summitracing.com/parts/mll-bp4002ct1 It runs very strong and the ol TH350 is holding up so far so good. I replaced...

    Np203 part time conversion?

    There used to be 2 part time kits available to change the np203 from full time to part time. I did the cheaper mile marker kit which you could convert the tcase from full to part time while installed in the truck. Took an hour or two but super easy and straightforward, you just swap a gear which...

    New here, building a 82 K10

    USA1 better than LMC or pretty much resell parts from the same supplier? My truck needs cab corners, quarter corners, lots of interior if I want to make it mint.

    pulls to right quickly if you let go wheel,zero tire wear for 18yrs.

    Could be a sticking driver side caliper or deterioration of driver rubber brake line (deteriorate from the inside and act as a check valve which allows brake fluid to caliper but doesn’t release pressure when off brake pedal.)

    How much HP will a th350 handle? New motor!

    My truck is 4WD and the crossmember supports the transfer case. I believe it’s as easy as moving the stock crossmember back 3” and drilling new holes in frame. Issue is you have to shorten rear driveshaft and lengthen front driveshaft. I’ve hear of some people moving motor 2-3” forward. But...

    Lares vs Cardone steering box reman not Saginaw?

    Here’s a quick video of the steering box flex. Can’t see any cracks in frame and all factory rivets are tight.

    Lares vs Cardone steering box reman not Saginaw?

    Had my assistant move the steering wheel and the steering box responds along with the rest of the steering with the slightest movement of the wheel. I didn't realize how much the frame flexes when rocking the steering wheel! I checked for frame cracks when installing new steering box and there...

    Lares vs Cardone steering box reman not Saginaw?

    The rag joint / coupler is the difference. Cardone steering Box used the dorman coupler that has more splines and the coupler has a mesh metal webbing layered in the rubber. Lares coupler is all rubber and less splines. The steering shaft bolts to either coupler and doesn’t contact the...

    How much HP will a th350 handle? New motor!

    Thanks!!! I couldn’t build my current 400 to those specs for that price and It’s a new block, no steam holes, etc. thought about LS swap but that’s a lot of work to get everything working, gauges, mounting points, etc. I’d rather keep it small block 400 powered. ETA shipment from summit is...

    How much HP will a th350 handle? New motor!

    Good point. I’ll relocate to near middle of intake and possibly change to metal filter. I like being able to see through the plastic filter for fuel flow and debris.

    How much HP will a th350 handle? New motor!

    I put Mobil 1 full synthetic in the transfer case. Can’t remember if it was 10-40 of 10-30. I should prob change it again anyway. I did the full time to part time conversion prob 12 years ago. It was the cheaper conversion kit with needle bearings not the better mile marker kit where you...

    Lares vs Cardone steering box reman not Saginaw?

    Replaced steering box, coupler, center link, and drag link. When just replacing steering box I noticed there is a little less play vs the old cardone reman. Still some dead zone in the center but apparently that’s how these were new. Old Center link was tight but boots tore so replaced that...

    How much HP will a th350 handle? New motor!

    Thanks for the detailed reply’s. I’m guessing my trans is stock with a modified valve body since it shifts firm. Who knows if it’s been rebuilt in the past 40 years. Since I’ve owned it for the past 22 years it’s always been fine except for no first gear when freezing temps. Hopefully it will...

    Lares vs Cardone steering box reman not Saginaw?

    1979 k10 My 20 year old cardone steering box is getting sloppy. I adjusted the adjustment screw on top but that really just changed the “feel” and it still felt sloppy. I’ve checked center link and drag link, all solid but I’ll probably replace while in there. Rubber steering coupler is oily but...
