Got your vans yet Mike?

[mljjones67]

[averagef250]

Gotcha.

So I have been taking to Matt and Phillip (the guys Dustin bought his last motor from in Buffalo), and they we talking about using the 6BT turbo... which got me thinking...

Has anyone seen a boost gauge that would work well in the F500 gauge cluster? I have seen an air pressure gauge in a bus that looks good, but it is way too high...

TIA,

Eric

What size is the gauge hole? I'm sure you can get a boost gauge from isspro or SW in the right size if it's a standard size gauge.

Matt seams like a pretty nice guy. He's willing to drive a bit further than he needs to drop the engine off at a shipping dock that'll save me a few hundred bucks for nothing.

Leaning towards the 6BT eh?

[mljjones67]

Dustin can you get me a spring??

[71PA_Highboy]

Nope.... not going to the 6BT... don't need the power or the reduced fuel economy, or breakage...

Anyway, If you need help with Matt again, let me know ... maybe I can assist.

regards,

Eric

I'll get you a spring Mike. Thanks for the offer Eric.

[mljjones67]

Let me know how much with everything and I will get you the cash. Thanks

OOPS!

The new engine's running great, but the tranny I used was a real pile I pieced together from throwaway parts I had kicking around. It would pop out of third on hard engine braking and reverse synchros were done so I figured I'd jerk it out today and replace it with a new one I had all cleaned up and ready to go. Well I put the engine and tranny in initially with the body off the frame. Come to find out the transmission will not come out through the bottom. I'm considering cutting all the rivets out of the crossmember under the tranny in order to get it out because I really don't want to pull the engine again.

Just a heads up for those considering going to an integral bellhousing tranny.

Got the plane tickets, will be flying down on the 11th of August. What do you think I should expect to get for fuel mileage from these beasts??? Do you think I could change the springs before I drive them home????

[averagef250]

I don't think I'd change the spring before driving it home. It'd increase your top speed, but you shouldn't really run the cummins above 2500 for sustained driving.

For the spring change you also need to make sure the IP is extremely clean so nothing can fall inside while you have it open. I'd want to do it at my home where if anything went wrong I wouldn't be stranded.

The breadtrucks average high teens from what I hear. Some say as low as 15 some say low 20's, I've never driven one.

That's hilarious! I love the way his turbo's right up there like a blower. That's too cool!

After seeing that I'm pretty sure a cummins can make anything cool.

Cummins Pacer anyone?
