Bottom end is toast - Need Guidance

Chinese crankshaft i believe


id would get an MMR short block

 

If you have the tools, time and $$$ then sure

i personally would find a teksid block, cobra crank and then pickup some forged rods and pistons. Get all that at machined at once and then assemble it from there

 

What are you trying to build and what is the application? Where are you located? [MENTION=10454]ScottyDsntKnow[/MENTION] has a couple teksid blocks that he just picked up. Give a little more info on your setup and we will talk from there.

 

I tagged him in that post so he should chime in here as soon as he gets on.

By the way, we cant see that thread unless we have an account.

 

I'm the guy who is running out of room to store the Teksids... although I think I have 2 sold this weekend...

There are 3 types of aluminum blocks, all will hold a ton of power regardless of what the internet says.
-Teksid is the first aluminum block made in Italy by Teksid who also makes blocks for Ferrarri. These blocks are good for 4 figures and about 87lbs. They are in all Mark VIIIs and 96-99 Cobras and some 01 Cobras.

-WAP is the first run of in house aluminum blocks by Ford to replace the expensive Teksid. They get a bad rap on the internet from e-racers for being weak but I have personally never seen or heard of one failing due to too much power. I'll be using one .020 over with internals capable of around 800hp and I will have no worries about it breaking. They are the lightest of all the blocks right at 80lbs. They are used in some 01 Cobras, 02-05 Exporer/Mountaineers, Mach1s and a few others. IIRC the 03/04 Aviators have them and the 05 Aviator had some but might have got the Aluminator which segways to...

-Aluminator is the upgraded WAP block for all intents and purposes. Its the heaviest of the aluminum blocks and is every bit as strong as the Teksid, if not stronger. Found in 3V Mustangs, possibly 05 Aviators, I believe some trucks too.

Here is a pic of a few of mine. Teksid is the dirty one from a Mark motor I just broke down. The WAP is the clean one I'll be using in my GT on the left. The Aluminator will look the same pretty much. Teksids are easily identified by the checkerboard pattern in the valley. The WAP/Aluminator have the diamond pattern.




As far as internals for you... TBTH a cast crank is fine for 90% of people. They are good for way more power than you'll hear on the internets as well as they are nodular iron. 700+hp and 7K+rpm. They are also lighter than the forged Cobra cranks by a good margin. The forged cranks are made by Kellog and came in all 4.6L Cobras and manual Mach 1s and honestly not really needed until you are approaching the 800hp range. But... lots of people use them just for peace of mind. They are getting pricey tho... $300+ plus shipping for a good one. Cast is free and actually better to use than the forged one if you don't plan on making stupid high power.

Rods and pistons... MMR I beams are cheap and come with ARP stuff and good for 750. For pistons on a 2V, Manley Street Masters are great budget pistons and at 18cc on a 2V will yield 9.5:1 compression which is perfect for a blower build. I'd use them myself if they weren't 8.5:1 on a 4V... too low for a Centri build. Total seal rings... all the regular parts for a rebuild after that...

If you are near NJ, I can sell you one of my blocks probably and point you in the direction of Fonse Performance. If not... I'd go on CL and find a Mark VIII motor. You shouldn't pay more than $300 for one. Sell the cast crank for $100 and try to get $100 for the B heads and cams and there is most of your money back.

 

The said modular company within most of these post are NOT the only modular builders in the modular community.

These companies dont play a mass market game. Individual attention to the customer is key. Im sure they had their mistakes, but ive never heard anything about them.

 

MMR=Might Make Raceday.

They sell good parts but I wouldn't trust them to build anything. They are all about volume, too many horror stories.

Here is another real good shop.

I've heard real good things about livernois

 

This!



for my build im planning on an aluminator block (ive got a 3v) with one of MMR's 1500SE rotating assemblies. I'm a cheap ass, so i'll be sending it off for machine work and assembling it myself. Lol
