  1. Piston to Valve Results

    Engine
    Degreed the cam and checked piston to valve clearances for my 351W. With a dial indicator the closest the intake got was .156" at 20 degrees ATDC while the exhaust was .251" right at TDC. With clay the intake was .165" and .075" radially. The exhaust was .230" and .165" radially. I think the...
  2. Need help picking out a new cam (SBC)

    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...

    Engine
    This summer I'll be converting my small block chevy to a roller cam like I decided in a previous thread http://www.hotrodders.com/forum/roller-rockers-need-guide-plates-495026.html. I was recommended the XR270HR by Comp Cams, and by Lunati I was recommended the VooDoo 20120710 XR270HR...
  5. 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...

  7. 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...

  9. Which Elgin cam is best for TBI Torque?

    Hotrodding Basics
    I have seen a few Elgin cams mentioned here, If I can't put a GM roller cam/lifters in my 1995 Yukon 5.7 L05 TBI block, I am curious which one of the following three would be the best from idle to 3,000 RPM, (the zone I drive/tow with my Yukon) CAM# W/1.5 LIFT @.050 Opens Closes...
  10. Choosing a cam for RPM Range

    Hotrodding Basics
    What is a good RPM range for a muscle car? A lot of the cams I am seeing have a operating range that start around 2500RPM or higher. That seems really high to me for a street car. Does the operating range of a cam dictate the idle speed of the engine as well? If the operating range of a...
  11. Stock Cam vs Aftermarket Cam

    Engine
    My son and I are restoring a '72 C20 350 w/4-bolt mains I bought from my uncle in Texas. The engine only has 89,000 miles, but has sat for 15 years. Our goal is to make it a good looking Street truck. Since the gas mpg sucked back when i use to drive it, we thought we would do some easy but...

  13. Camshaft ID ?

    Engine
    OK. Here's something to chew on for a while. I have looked up every combination of the following numbers found on this mystery cam I have and can't get a lead on any of them. The cam was pulled by my apprentice and she didn't keep the lifters - so - I know not if it were a solid lift cam or...
  14. Cam and Performance Heads vs 383 Stroker for SBC 350

    Engine
    I have a bone stock 1980 vette with a SBC 350 and a 700R4 transmission. The car is slow as snow and i want to make it faster, but i dont want to piss off my wife and neighbors from the noise of a super loud engine. I have spoken to a local performance shop that said they could stroke the engine...
  15. Phantom Mysterious Engine Knock - Losing my mind

    Engine
    Hey everybody. I've got a strange light knock.. sounds a lot like a rod knock, but it goes away when I'm over around 1500 RPM or so. I checked my oil, and cut open the filter and found bearing babbit.. so my first thought is it was a rod knock, so about 2 months ago (after I found bearing...
  16. Valve Lift on stock Vortec heads?

    Engine
    I pulled a set of vortec heads off of my 1996 k1500 vortec 350. I plan to use them in a moderate build of a different 350 that will be getting edelbrock performer rpm intake and carb. I'd like to throw a cam in it too, and I heard that vortec heads have some restrictions as to the lift they can...
  17. Fair Machine Shop Pricing?

    Engine
    I am looking to get the valve guides (and I think I need the spring seats cut also (never delt with heads before)) on my vortec heads to handle a higher lift. What is a rough estimate of a fair price I should be willing to accept? I've never delt with a machine shop before so I wouldn't know...
  18. Cam recomendation

    Hotrodding Basics
    I am new to the site. I am looking for a cam and rocker recommendation for my 1955 Chevy 4 door driver. What I have thought about is a "Mild" cam, whatever that means technically. I want to run on pump gas and go to shows, no racing. I have a sbc 400, dish pistons, stock rods, Vortec heads...

    I have a 383 stroker and wondering what the power would be. from top to bottom. Holley 750, edelbrock performer eps intake, the corvette 882 heads with the large valves and port and polished and machined to I think 72cc chambers, the thinnest head gasket I think its .015, Bored 30 over with...
  20. 383 Cam Selection for Truck Use

    Engine
    I have a 383 in my K2500 that's using TPI right now. Originally, I was going to turbo it, but I ended up having to buy another vehicle bc my daily died (13k+ out of pocket cash gone T_T). So instead I want to just carb it, and change out the small compu cam. I have been reading a bit on this...
