Re: 67 c30 cummins swap

Stay away!

I would purchase NEW bosch 215 injectors. Factory 215's will get you close to 500hp with other mods.

Re: 67 c30 cummins swap

Would like to go with something a little bigger than stock. Will be adding a turbo and bigger pump at some point.

You dont need to. That 215hp engine will support more power than the trans and chassis will handle.

500hp @ the wheels is barley leaning on it. A factory turbo w/mods will support 500hp.

Re: 67 c30 cummins swap

I've got 4k gov springs to put in, grind the fuel plate, and add some timing. Other than pump, turbo, and injectors what mods are there?

Re: 67 c30 cummins swap

You have to have the valve springs to.

Modded hx35 or modded he351cw 35-40lbs. boost, bump the timing and playing with the plate and screws and your near 500hp.

Re: 67 c30 cummins swap

It depends on how crazy you want to get. On mine I'm having the intake plantium machined off and a runner style intake also larger valves from Hamilton cams. You can put a cam in it. If you have a pump some delivery valves also a pump cam. There are a lot of things you can do it just depends on how crazy you want it

Yes it will get close to 500HP but it is really hot and turbo life is not the best. A turbo upgrade is a very smart idea around 350HP. I will bet that there will be a lot of vertical scratches in the rear cylinders from ring scuff without a turbo increase. If you start out with a 215 pump don't mess with the DVs. You already have 181's which are pretty good. Most larger DVs run hot and smoke because the fuel timing gets messed up. You want your fuel injected quick and early. This gives more power than late entry fuel along with cooler EGTs. If you want way more fuel than the turbo can use it takes about $200. Buy a good 4k GSK with valve springs and grind the fuel plate to a 100 profile. You will never ever clear it up with a stock turbo. I ran this setup on 362/475 twin setup and still had plenty of fuel. For injectors spend the money. You want quality parts here. Period! Always buy injectors bigger than you need and use the AFC and fuel plate to limit fueling. Power is easy to build and you will want more in short order!

Re: 67 c30 cummins swap

Hahah man I don't know the last time I saw a Cummins that grime-free. Usually I see about 1/2" of soot and oil.

Thats what happens to 20 year old work trucks. Remember 1998 was the last year of the 12v. Mine just turned 20 this yr. Wish I had a pic of the engine just to show how clean it is. I've never cleaned it. I doubt the previous owner did either.

Cant wait to see this swap completed!

Re: 67 c30 cummins swap

Kobush-What motor mounts did you use? Did you fab them?
Do you have any better pics of them?
You swap is looking awesome, and I am fixin' to start the exact same swap on a 72 one-ton myself.

I just wish my motor was a 215 motor.

Got most of the metal work finished up on the core support last night. Getting motivated to get this thing on the road.

Re: 67 c30 cummins swap

Finally got back to work on the truck after a little break from it. Ended up having to pull the cab to make a few changes to the crossmembers and do some clearancing on the firewall for the down tube. The truck is put together now and working on the finishing touches to get it on the road. Planning to get some pics up soon.
