What's the best way of contacting DPR? Email or phone?

I shot him an email yesterday (holiday weekend) but I know some guys are so busy with the shop they don't email much.. Thanks.. Giving him a call Tuesday.

I was reading up on cast cranks; just couldn't stomach using this one. Every thread asks the same question over and over.. "Should I use this cast crank?" I have yet to see a positive reply to that question... Hopefully I won't take a loss on my impulse buy with the SCAT I got. Smile

When Jake Raby says he builds his 1,000+ engines on DPR cranks... I'm getting a DPR crank.

Here we go:

I'm not sure about this welded area. I will be looking pretty hard at it once the case halves are clean.

The heck?? These grooves don't go all the way through, but I don't like them. They will be radiused to help prevent future stress cracks.

Crankshaft is ground .010" under on all journals. #2 main bearing was showing copper, and the #2 cam bearing halves had some corrosion-type damage that I'm not familiar with.
Lifter faces are worn out - flat. The cam looked pretty good though. I'll hang on to the crank and cam gears to go on the rebuild; the cam is a +1. Distributor gear and drive both looked pretty good.

Planning on doing the alternator stand stud-removal mod for a bolt-down stand; same with the fuel pump, I'm planning on using stock T4 fuel pump triple-square drive bolts, but probably just going straight into the case and not an insert. Mock-up will tell!

Case specs coming after the halves get done pickling in degreaser.. they nasty.

Grooves are just from the engine tin and nothing to worry about.

If you are going to remove engine case studs for bolts, install steel inserts like Time-Sert to prevent the threads from being worn out all too soon....

Interesting weld spot, too bad not also welded in the lower pocket that tends to crack if bored for bigger cylinders.

I ceased use of DPR cranks in 2012 after using them for almost 20 years.
That's all I am willing to say on the subject.

I'll drop a supplier that's unwilling to meet my requirements for quality and consistency faster than any other reason. I'll give them several chances to remedy the issue and I'll even write them a formal letter to explain the conditions and corrective actions that I require.

If they don't conform, they are not given any further chances.

You did just fine saying you dropped him as a vendor without saying why Jake..

My most recent post was a blanket statement.
