    hey guys im needing suggestions as to if it is even possible to do this:

    My buddy has a 1980 crew cab 350/465/205 60/14b with 4.56 gears and some metric 32" tires, He mainly uses this to tow his 28' camp trailer and his utility trailer. his current motor is getting tired and has problems pulling grades above 50mph and he complains of no power in 4th.

    I gave him a 350 out of a 76' that i junked, it runs, but has low oil pressure-5psi when warm 25 when cold and it smokes a bit, he is wanting to rebuild it. is it posible to do this with $1000? if so what combos should we look at? i told him to spend the $1400.00 to get the 290hp gm crate, but he thinks he can build a better motor with more hp for that price? Is it doable or is he drinking his bathwater?

    Easily do-able. You could probably decently rebuild a 350 for $500.

    I paid about $900 for a totally rebuilt 350 with a new crank and the heads completely rebuilt. The build did not come with any high performance parts at all just your average oem equivalent but it does have flat top pistions.

    It has a 12 month 12k warranty which will have expired by the time I get the damn thing on the trail!

    I called a reputable shop in my town and told them what I wanted. I just had the basic rebuild done with their parts. They gave me reconditioned connecting rods and oem valves. The heads I had were loaded with some outrageously heavy springs so they put in oem springs too.

    So far I have broke the motor in and it runs fine.

    FWIW, that only applies to engines that are speced out for that vehicle. if the truck happens to call for the 290 hp GMPP engine, then the 36/50,000 warranty would work. it also has to be installed by a reputable shop IIRC.

    i did one for my own truck in '99, reconditioned the heads, bore and hone, tank and crack check everything, align hone, checked the rods out myself, they were ok, reconditioned crank, new pistons, rings, bearings, cam and lifters and i did all the assembly work myself for $800.

    I think blazin_blazer was suggesting that if he built the motor himself he wouldn't get the 36/100,000 mile warranty that he would get if he went the the 290 hp GM create motor.

    the 290 hp engine doesnt come with anything remotely close to a 36/100000 warranty. its 12/12000

    i took a running 350 and rebuilt it and it cost me about $300 total. i bought the kit from northern auto parts and took my heads and block to the local shop for valve job and jetwash the block for $110. is probably the most reliable/most power engine i have for the money i have into it.

    i have a place saved to my favorites at work that has rebuilt longblocks with a 5yr/100,000 warranty, and it doesn't matter who installs the engine. i will post a link to this place tomorrow. i have a friend who bought a 454 longblock from them and then got the rest of the stuff he needed from summit and swapped his 84 k10 over to a big block, its been about 4 months and no trouble yet.

    Sorry for the highjack but in about a year or so im going to do a 454 swap in my k5 i can pick up a running 454 for 600 with tbi but no harness or computer. I talked to a local shop i they said they could rebuild it for about $1000 to $1400 depending on what i wanted with a 1/10,000 warranty. I think he said for a 383 stroker it would be about $900 buck, but which would be the better route?

    A budget rebuild could be easily done for under a grand if you're doing the work yourself. I would suggest putting some good heads on it, Vortecs work well, and putting a larger cam in it, with the 4.56's and 32's that motor is going to spin some R's on the highway, get a cam that will put the powerband where you want it. That GM 350 is a good motor too, I would again suggest a larger cam if you go that route. Stock cams are anemic. A set of headers and good exhaust would help too, if not already equipped.

    After working in an install place I know why they do this and how it works.

    Because 90% of the time, if the engine fails they will pin it on the install. That is unless you have ALL the proper documentation and can prove to them without a doubt that it was their fault..... but even then it is up to their "lab" to determine if it was their fault.

    On top of that it will normally take them about a year or so to get you your cash from the warranty.
