    3.75 backspacing ?

    Typically the only time the wheel track is widened with aftermarket spindles is when you have a truck with drum brakes and convert to disc brakes. The disc brake spindles move the wheels out some but its less than a inch. If the truck already has disc brakes the track width should not change.

    350 rebuild with a little more power

    Why not just leave it alone and put that money into the 496 build? Never understood why people want to build a engine to get them by while they build another engine. If it needs it, rings and bearings, fresh hone, polish the crank, RV or torque cam and be done. The heads that come on those crate...

    checking compression when alone

    I always did my tests with the engine at operating temp, or as close as it could be after taking the time to remove the plugs and screw in the gauge and check each cylinder.

    replacing pistons only

    Ok first of all, You might be able to replace just the pistons without removing the engine if you can get the oil pan off and the connecting rod out. Usually pretty tough to get the room. Second, stay far away from the 290hp 350 crate engine. It is way over priced and the only difference than...

    I appreciate it but its my understanding I cant use a V6 ECM. I`m still trying to verify that it has to be 85-86 truck only with a 305 or 350.

    OBD1 help

    Ok, another update. Met a guy on another forum and with his help and after he went through my carb and correctly set everything we discovered that my ECM would not send a signal to the mixture control solenoid. He gave me another ECM to try and it worked. Truck ran strong, CEL disappeared. Then...

    5.7 vortec swap need help/advice

    I'm already back in Sacramento. Had to take the trailer to the DC in Woodland, ca. We don't service the Reno store anymore so I just ran up to get our last empty. Use to deliver a lot up there when I did flatbed. These days I stick mostly in the Sacramento area.

    5.7 vortec swap need help/advice

    Yeah to be legal I would have to use any emissions from that vehicle. So if I pull a engine from a 1997 chevy truck then I need everything that 1997 chevy truck has. It's not as complicated as it counts and compared to what my smogged out 305 has anything 1987-up would be a lot easier. I was...

    IIRC=If I remember correctly following along because Im considering doing a vortec swap into my 85 GMC c1500. Unfortunately here in California I need the smog crap intact for a legal swap.

    Ok, bringing this back up. I need to go back and read some of the comments to refresh myself but here is the current situation, Finally located the correct 3 port EGR solenoid and replaced that along with a new EGR valve. I disconnected the battery for a few minutes and then started it up and I...

    Crate Engine help!!!!

    It also has a much better head. I know that 290 HP number is a little mild so I'm willing to bet the 330hp engine is closer to 350hp. My 290 HP engine came in a car I got but the 4spd helped it and it really suprized me but it did beg for some gears.

    Truck wont start help me please

    So you said it was running before the fuel pump swap and all you did was swap the pump. Did you change anything else? Have you verified you are getting spark? Are you getting fuel? Is fuel in the tank? Are the fuel lines on the correct ports on the pump?

    Crate Engine help!!!!

    Isnt a 1987 truck already TBI? The 290hp 350 wasnt bad in my 65 el camino with a 4spd but it doesnt belong in a heavy truck. It`s the same engine as the 260hp with just a L82 camshaft and a bigger pricetag. 300hp from a 350 is pretty easy to do these days but agree you want to focus on low end...

    400 sbc build

    Actually Rich I was 13yrs old when I worked on my first car. A older friend had a 1969 camaro and had just put in a very mild 383 and couldn't keep a tranny behind it. I cut my teeth helping him pull the tranny and worked on his car u til I got my own a few years later. You claimed the 280...

    400 sbc build

    LOl Ok Rich. You cling to your simulations and I`ll stick to the real world. My argument from the get go was that you claimed the 280 magnum, sorry dont know grind numbers off the top of my head like you do, is not a torque monster. I know for a fact that it is. I didnt learn that from a...

    400 sbc build

    No Rich, with similar grinds. Get real. I've been around the block enough times to know how the camshaft is going to act. It's not rocket science.

    400 sbc build

    No offence Rich but I don't trust simulations. I am going off of actual builders dyno sheets I've seen of different forums.

    400 sbc build

    You have to remember that the 280 Magnum which is [email protected] will act much different in a 400 than it would in a 350. The 400 is bbc bore and stroke pretty much. It can take more camshaft and not loose torque like the shorter stroke engines will. It will depend on the heads but if you put a...

    400 sbc build

    Just because the book says 2000-6000 doesn't mean that's the only operating range. That cam in a larger engine like the 400 sbc will start making power sooner than 2000 rpms. Think about it, it's basically a bbc engine in a small package. Only difference to the 402 bbc is the heads. The 280...

    400 sbc build

    The 400 sbc can take more camshaft than your regular 350 engine. The 280 magnum in a 400 will make more torque than his tires can handle. And there is no way to say how much power would be lost or gained without using a dyno. I know of a 402 bbc which has a very similar bore and stroke to the...

    engine is popping through the exhaust.

    Any exhaust leaks can cause this. Replace the gaskets at the head and the collector and see if that fixes it. If this just happened out of the blue I dont suspect anything with the timing. If this started happening after messing with the timing then that could be your problem.

    400 sbc build

    In a 400 sbc that cam will make plenty of torque. That is a pretty common set up and would run good. Yeah there are better grinds available. Im not a big fan of comp cams but I know a few who have used the magnum line with great results. This 406 build uses a similar spec`ed lunati cam and...

    Engine help

    a 1984 should have the electronic qjet. Removing the smog pump and air lines shouldnt have any issue but sounds to me like your talking about the choke. When the engine is cold it need a fast idle until it warms up. Then you can blip the throttle and it should turn off the fast idle and should...
