I would be interested in knowing some of the Camshaft options.

I have SD4 I am working on rebuilding and converting to EFI with a '801 head.

I should be able to get some camshaft specs this weekend

Thanks

This is really cool! Is it possible to get a price breakdown for per part basis, like block, head, crank, etc. I know I can't afford the whole lot, nor would I have a need for the whole, but individual parts would interest me a lot more, and others may feel the same.

Thanks!

I am also interested in some dry sump parts if he has any. I have a pan right now...
DustyMN JUL 08, 09:55 AM
I'll check to see if he has any dry sump parts

Here's a price breakdown:

Engine blocks $800 - $1000 each

Cranks $500 - $1000 each

Camshafts $100 each

Misc rods and pistons and heads $? (will check)

KRP Racing block $1500

Complete engine $15k

He said he does have some dry sump parts and will look through them and get back to me soon

He asked if the engine is for street use or racing, he said instead of a dry sump he always recommends an external belt driven single stage pump with a vacuum pump on it, he said this setup will make more power than a dry sump system

It is a street engine. I have researched running an external scavange pump, however, finidng those pumps for a reasonable price has not been going well. The cost new is prohibitive. I even bought an oil oump from a Ford duratec engine to try and adapt it. However i need to figure out the flow rates of the duratec pump and SD4 pump or it could all go south.

What do you think a reasonable price would be. I have a couple sitting on the shelf.

Radar, KRP is still around. Call or e-mail me for the number. I have a brand new, unused, KRP Fontana block with a Chevrolet bell housing bolt pattern. Original cost is $3500. Make me an offer.

Kansas Racing Products doesn't seem to be around any more, so I'm not sure. They were the main aftermarket producer of SD stuff, after GM stopped making them.
