  5. Cam timing question on SBC 350H

    Hotrodding Basics
    Hello all, So this is basic, and probably kinda dumb... but here goes. The previously running 350 in my 29 coupe had noisy timing gears in it. I replaced them with some quiet ones as follows: I rotated the crank shaft to TDC on #1. With spark plug out and used a breaker bar on the crank...

  8. Fresh engine rebuild, has sat for some time.

    Engine
    Be warned this is going to sound painfull and idiotic to some people but hear me out. :spank: So without getting into nitty gritty details, i yanked a 400 sbc out of a project-gone-bad old camaro, had the block inspected, and decided to use it as a builder. Long story short, i had everything...

    Engine
    I plan on home porting my heads and intake on my 350 sbc. I have been told that i have picked out a bad cam for my setup (which is likely because i was like 17). I was wondering if anyone could give me a good suggestion for a flat tappet cam from summit. I am running this setup in my 3rd gen...

  11. SBC 600hp+ pump gas hyd.roller - Proven recipe?

    Engine
    Hello, Ok you have spec'd various engines on this forum but I can not figure out an engine that would be the absolutely best small block for everyday and occasional strip use. Either they fall short of 600hp or they have 13-15:1 CR which is not desired for street. This build thread is...
  12. Cams to Match Heads

    Engine
    Hello, So I have a stock pre 86' sbc 350 in my 1975 F150 I picked up a few weeks ago. It's got a bent valve and a wicked exhaust leak. So I was going to put new heads and headers on the motor, and figured while I was at it that I might as well put a new cam in. I'm pretty stuck on the heads I...
  13. Having trouble starting my just-rebuilt SBC.

    Engine
    Hey all. So I have a 79 camaro, 350, HEI distributor. I just finished assembling the motor and wiring and when I'm trying to start it, it just keeps cranking and seems to spit puffs of gas out of the carb. To me it sounds like the cam and crank timing is out of whack and unfortunately I didn't...
  14. Metal in SBC question.

    Engine
    I was running the crappy rocker arms by proform and the locking nuts backed off. They basically gacked the hell out of the self aligning ridges and some of the actual arms. Do you think I should have to do a rebuild or just put a magnet plug in the oil pan? It was idling while I was trying to...

  16. 305 cheap build (need opinions)

    Engine
    I have a 87 Monte Carlo LS with what I believe to be an HO 305. The reason why I'm not sure is because it's made of so many different car's parts. Not sure if the engine is stock but the head's casting was 081 so I assume it's an HO. From research I found that it's an LG4 which was machined for...

  19. 406 sbc stock crankshaft nitrous?

    Engine
    Recently built a 406 sbc. I ended up getting a nitrous kit for a song after I built it and am debating on whether the motor will hold up or not. I would re-gap the rings but my main concern is the stock crankshaft. Will it hold up or not. Its approx HP is 450 and ft lbs of trq. I-Beam push rods...
