    Just get the kit that rolls the motor 10*. The tranny is not going to care and it'll work flawlessly and you can enjoy your truck. /forums/images/graemlins/thumb.gif

    Re: More conversion ideas needed from conversion experts/diesel

    Ive seen no cummings conversions in GM trucks yet(but I have seen the step vans with the factory setup)--a mobile home dealer near me had a 1978 GMC crew cab C30 he used to tow mobile homes to new england from the factories in indiana--it had a 454 at first,but he lost the motor the second trip out,next trip out the TH400 started slipping--he was going to sell the truck and buy a bigger truck like a C60,but he found an Isuzu box truck 24 foot long that had hit a low bridge and totaled the cab and box--he bought its Isuzu 6 cyl.diesel and the matching tranny (5 spd std.)and had it converted at his shop.The motor and tranny fit very well,with no major butchery nessasary,he was delighted with it from the first day it was done,said he'd never use a gas motor to tow again,he got 18-22 mpg empty or towing,it never goes under 70 mph on hills,no bogging out like the 454 would.When he sold it there were many local people who knew of the truck that wanted it pretty bad,and he got good money for it too!. /forums/images/graemlins/crazy.gif

    Re: More conversion ideas needed from conversion experts/diesel

    Ive seen the 10 degree tilt on two trucks... one in real life and one on ebay... Im not so wild about them...but it does bolt up and there is a lot to be said for that
    as to the IZUZU conversion... interesting but I think the cummins would be a better setup for my needs

    thanks for the good info... the more the better

    Re: More conversion ideas needed from conversion experts/diesel

    Why not just use the smaller 4bt and mod it to make an appropriate amount of power? It just makes more sense to me...cheaper, shorter, lightweight. Maybe try finding a newer 4bta with higher hp and tq ratings.

    Re: More conversion ideas needed from conversion experts/diesel

    To acheive the same power that motor has to work a lot harder and EGT's are a lot higher at comparable power numbers,and it can not sustain the max power output for very long under load. This is a truck that sees a lot of towing, and while a 4bt would work out, a 6bt would be much happier than a 4 under the hood.

    Re: More conversion ideas needed from conversion experts/diesel

    I dont know what happened to your other thread, so i will answere a couple questions again. EDIT: I found it, i see its been sticky'd /forums/images/graemlins/doah.gif

    The reason for the tilt in the GM adapters is actually very simple. It was the only way that Cummins could repower P-30 step vans without major work like lowering motor mounts and dropping the tranny lower. The 10* tilt was deemed acceptable by Cummins, and with the lean would fit perfectly in the van's engine compartment. No GM P-30 step van left the factory with a Cummins in it, they were all repowered, most of them replaced 350's, 6.2 equipped bread vans were left alone for the most part.

    Not everyone has had to do a body lift to mount their 6bt's, it really depends on how the motor mounts are set up and how much axle clearance you have for the oil pan.

    And again, all 6bt's are turbo'd. Thats what the "t" stands for. 12 valves are not computer controlled, 24 valves are. The early (think W-series Dodge) used the VE pumps, which are fine until you want to bomb the motor. Later 12 valves (think dodge 94-98.5) had the P-series pumps, which deleiver an insane ammount of fuel, and if you wanted to bomb the motor, this is the pump you would need. Installation of either a VE equipped 6bt or a P-pumped motor is going to be the same. No matter what you should run an intercooler, whether the donor motor came with one or not. Its not a "must" but is highly recomended.

    VE pumps are more than enough to run stock or do a mild build, but they do have their limitations.

    Re: More conversion ideas needed from conversion experts/diesel

    Cam, on The DieselPage.com Forum there's at least one member who did the 5.9 swap (85 K30). Not sure of the tranny although, could be a modified TH700.
    His name is Britannic. Sorry no email adress.
    Maybe you could try it on the non member part of the DieselPage Forum.

    Regards.Walter

    I have a 1991 V3500 crewcab 4x4 with a 94 12V Cummins NV4500 5spd, 205 T-case.As far as the conversion very easy...
    I had to trim front crossmember for the crank pulley and cut a small section for the a/c compressor. No body lifts,beating on fire wall , Engine sets level ,Wiring very easy,as for motor mounts use stock 6.2 Diesel mounts on frame to custom Cummins mounts.I made a new crossmember for the Engine and bolts up the the stock location.

    I will send phot's if needed. any questions just ask.
    I do sell the mounts for the Cummins engine.

    Thanks
    Scott
