    New wheels

    What size of rear drums do you have , 11" or 13" ? I have a '79 K20 full-floating rear axle I just bought and it seems to have 11" drums. Much smaller than my only 3/4 ton I've had or any of the 1 tons.

    Slicks with 10 bolt

    I'd go right to the steel billet driver's side carrier bearing cap and 1/2 studs and forgo using just the reinforcement type diff cover. Alloy 30 spline axles and an aftermarket carrier are defiantly the way to go also ! Stick or auto, BBC or SBC , Nitrous / supercharged or NA, how bad will...

    Shock/Sway bar ?

    I've had great luck with the "Gas Magnums" on full size trucks and wouldn't consider the "Gasmatics" which I installed on my wife's blazer - not happy with them at all !

    Good engine blocks for a build

    Dogbones = the factory "paired lifter retainers" ( for lack of another better term), and Spider = their spring steel "keeper plate". All part of the factory roller cam/lifter system, just look for pics and it'll be clearer than mud.

    350 ID Help

    There is a 1974 350 and a 1978 350 with CMR also. 145 hp and 220 hp. The '78 is a vette listing - don't know if that helps the chance of being a 4bolt !

    It's a CMR suffix

    350 ID Help

    I think it is a '74 and if so it came with a 2bbl and an auto trans. Casting code on the rear of the block tells us more , but nothing will tell you for sure if it is 4 bolt mains without looking.

    Gm 350 #10067353

    Vortec heads, a roller cam , and what's probably a point and a half of compression you think would be only about 15 hp ?? I'm guessing 40 - 50 hp !

    Tick at start-up

    Still sounds like a bad lifter , unless it's an oil pressure issue .

    Tick at start-up

    A lifter is bleeding down while it sits. Is this a high mileage engine ?

    Gm 350 #10067353

    This is a great bargain in my opinion ; http://www.summitracing.com/parts/nal-12530282/overview/ Vortec heads, 9.4-1 compression, one piece rear seal, and a roller cam ! What's not to like ? :party36: For $30 more you can buy the 4 bolt main version. If you do change the cam in it - the...

    Good engine blocks for a build

    I couldn't agree more, a late model block also has the one piece rear seal. A good used version of this era of engine alot of times will be a cheaper and easier rebuild. Cylinders that only require a hone and new rings, roller lifters that can be re-used , and vortec heads too. Better stock...

    Axle identification

    Pull the covers and get the numbers off of the ring gears or count the teeth already. Just mark a tooth with a grease pencil or welder's chalk and count, do it twice to remove the doubt of error. Nothing like knowing for sure what you've got.

    Best rear locker/ best price?

    Detroit TrueTrac, it is a all gear bias-sensing limited slip. Smooth as an open diff and strong as all their products. Lockers are harsh On-road and will push you straight when its slick unless you let off the gas ( rain , snow, or ice). There are different needs for each scenario , and for...

    400 SBC from a RV

    I don't know what they're thinking, must be plenty of 20,000 mile,( or less ), 440's laying around for $300 or less !

    14 Bolt Differential - Lock

    The Detroit Locker is the least expensive ( of his selections ) at "Tom's Differentials" @ $479.25 , and you can probably install it yourself since it goes into the stock carrier and replaces the cross shaft and spider gears. They work great but are alittle harsh . The Detroit TrueTrac would be...

    14 Bolt Differential - Lock

    That rear axle should also already have a Detroit Locker factory installed.

    350 Upgrades & Progress

    All the way down to where it would've been easy to replace an old worn cam and lifters - but no go !? And maybe a new oil pump and oil pan gaskets too !? Looking alot better. Is this the original engine and is it high mileage ?

    My budget l31 build

    The cam's rpm band will be 3,000 to 6,500 in a 355 (will come on good after 3,500 rpm), their's must be a typo @ 1,500 to 6,500. A 600 cfm carb ? Budget ? The cam kit alone is $840 !! Make sure the springs you buy will work with the cam you buy, I don't think the ones listed match the cam...

    Piston to Deck Clearance

    Has this engine been rebuilt ? Yes, you'll have approx. .054" quench with an .015" gasket. Not the best - but could be worse , if your dynamic compression is too high this may require alittle more octane.

    Thanks for the update, I know all about being too busy. I'm too busy to worry about my personal projects also.
