Talked to the shop, they feel a 224* is as much as I can go and be sure to pass emissions.

Where should I order the double roller timing chain and oil pump from? When do you replace the water pumps on these motors? My motor has 64k miles on it, should I replace the water pump now?

224 doesn't tell us anything about the cam timing. You need the cam card.

Post the cam card online and we can take a look at it and tell you what's up.

If you're running cats and you have a wide LSA, you won't have a problem.

I would guess that the first one would be tough to pass emissions with.

The second one is very similar to what i have (and i purchased it because i felt i could probably pass emissions if i needed to). A 113-114 LSA is about all you can get away with, but you won't be disappointed in the performance

If your criteria is must pass emissions the cam manufacturer will know best..... if they can't tell you go to a different manufacturer.

Comp Cams actually has a pretty good tech support line. They can and will custom grind any spec you want if for some reason they don't already have one for your needs
.
I know your in a hurry Doc, but if not passing emissions really is a showstopper take a little time and do a little homework.

I called the cam manufacturer and the 1st cam should pass. So I ordered it along with springs, pushrods, gaskets and a double roller timing chain..

[QUOTE=docwyte;7816994]I don't think it's shameful of CPR at all and I happen to agree with him. It's very disengenous to advertise a price for a "rebuilt" short block and then read in the fine print that it's not assembled! That's not a rebuilt short block, it's just the parts TO rebuild the short block.

Actually, there is nothing disengenous about it at all. Like buying a new car, you start with the base price and add options and accessories. Assembly is an option just like adding a stouter connecting rod.

There is a bright yellow link saying click for pricing and details. The first option in ALL CAPS asks you if you want it to be assembled and tells you how much extra that is. So if you can read, and we give our customers that credit, you don't have to read but the first sentence. Nothing hidden, nothing disengenous. You "cannot" make the purchase on the site without being confronted with answering that question and others, so there are no "buy now, get surprised later" issues here. You just need to be able to read.

Mike,

The confusion comes when looking at rebuilt short blocks the assumption is it that it comes assembled. While it is listed that assembly is an additional charge and yes, we can all read, it's still a surprise.

The fact that I'm not the only one who was confused and surprised by it means it could be listed or explained more clearly on your site.

First off I appreciate what you do for the community, but this small portion of your site could use some clarification.

I just went to your site and listed under
"Short Block" Rebuild includes: on the last included point is
“Assemble Short Block Engine” So it almost reads as the $1999.00 would provide an assembled Short Block and the Customer will assemble would be a $600.00 reduction in price.

In reality you’re offering a Small Block machining and parts prep service. There really is no “Rebuild” for the advertised $1999.00.
