The 70 crew's progress-modifications and cummins swap

[460 crew]

Here are a couple pics of the cam and lifter that failed for your viewing pleasure. That lifter and lobe was all oiled up untill i wiped it alll off. I think the truck just wanted some attention. The new set has been installed and I drove it home lastnight and only a couple little oil leaks out of some bolt holes, cause we took a little too long to put the pan in (fighting it) with the RTV drying. I'll have them sixed tonight. It has a little more pep,is a little lopey on idle and is smoother over all. Overall i'm pleased but I still want to see what bolting the Doves on will do for myself.

What do you have right now for heads? D3VE? What is your current compression ratio? If you currently have a motor build around D3s and have 9ish compression then slapping on some DOVEs is going to put you through the roof on compression.

I think you are smarter than this and you are going to tell me that you currently have 8.3 compression because you are running stock D3 heads and stock 72-83 pistons. If so, then the DOVEs will put you up to 9.3-9.5 compression and that is a good thing.

I have D3 heads right now and when I pull off the current heads I was going to figure out my deck height and all that, I don't remember what pistons I have except for them being hyperkentic so everything is still kinda in the air with what I wanna do. I might just leave it alone, as plans are for a 5.9 cummins in the next yr or so.

Well as of today the crew has disks on all 4 feet now and stops better than ever. I splurged for the Blackbirds coversion with non ebrake calipers for now but going to upgrade later to the e-brake ones. Kit was complete except for the crush washers that go on the banjo fittings. Took about 45min-hr a side with repacking bearings, new seals and all that jazz. Had the GF pump the pedal for bleeding and WOW is it a huge difference, even when the drums were adjusted perfect they didn't compare.. i'll take some pics in the morning. I'm seriously not even worried about putting in a hydrobooster setup in the near future. It can wait, as i'm more than happy now. 2 thumbs up on BB conversion!!

Here are a few pics. I still have to weld on the tabs that hold the brake lines in place on the axle.

very nice. what size rotors are they? these are off a f-450 and i think are 14.5. they should slide on the same, you would just have to extend the braket out. those look pretty big they might be the same.

[rjewkes]

so did those bolt to the stock rearend where the old backing plate went?

or was there modifications? Write up?


and is that a dana rear or a ford nine incher?

how close are the backing plate mounts between the two?

sorry for all the Q's.

edited to ask did you also have to change the master cylinder?

[460 crew]

TY These are only about 12in, didn't measure them b4 I put them on. I need to call up BB and find out what all the pieces are off of for replacment later down the road.

The conversion is for a 70-79 D60 full floater. Yep they bolt up right where the old backing plate holds all that crud with the 4 mounting bolts. I'll have to scan the directions for the proceedure and post them. As usual i got excited and didn't have anyone out there to take pics while I was doing it, and I'm lazy. I'll be sure to take all the pics when I change over to the emergency calipers with new cables and stuff.

So did you have drums all the way around and now you have disc brakes all the way around or did you have front disc before? If you have front disc before and putting on rear disc helped that much then I'm really shocked. Usually adding rear disc brakes doen't help that much.

[460 crew]

Yep I already had a D60 Front with new calipers and drilled rotors, that was put in over 3 yrs ago and just 2-3 weeks ago put new pads on that. I wasn't expecting that big of a difference either but I'm more than happy, even the GF was impressed with her driving around the block.

Also Robert I forgot to reply to the MC booster ? It is a MC for a 78-79 4x4 and the booster is the smaller 7in drum/disk booster from a 69 250 application I think. It was the only one that fit in there with the 460 valve cover.

[rjewkes]

sweet, thanks. i'll have to see if they have the stuff for a 9"er.

be a while though.

[RebelRider]

Sweet conversion!

[460 crew]

As fate would have it necessity has take over the upgrades area and I had a driverside motor mount rip out for the 3rd time and it PI$$ed me off so bad on my ride home babying it that I ordered some of Autofabs new 460 conversion mounts they have for the highboys now on the way home. The L&L's work for alot of ppl but for some reason they don't like my truck, out with the old and in with the new. Here are some pics.




And installed. Only prob was the low mount alternator bracketry hangs to low and hangs up on the crossmember. Since the engine sit's lower now and the radiator was in the wrong spot I opted to just a little trimming on the shroud and lowering it a bit to compensate for a temp fix until i have the money for a diesel conversion.
