Mustang 331/327 build
 

Alright, this build is finally underway.

Ron (94cobra69ss396) and I pulled the motor out today and tomorrow I will start disassembly and some cleaning of the parts that will be reused.

The plan (as of now, subject to change, void where prohibited, etc etc) is to check the cylinders to see if they are out of round - if they are, the block will be bored .030" over and will be 331ci with either the CHP street fighter or pro street (depending on $$) stroker kit. If the cylinders are still in good shape, I'm going to go with a 327ci with the pro street kit.

As a few of you guys already know, we came up on a killer deal on a Paxton Novi 2000 blower, so that'll be going on. I've already purchased new 180cc aluminum heads, but I'm still on the lookout for an intake manifold and have to purchase a new cam and a few odds and ends before it can be finished.

I don't really have a timeline on this right now because fall semester starts in 2 weeks, but I'm hoping for the car to be on the road again by November or so...:drink:

That thing is going to be a monster. I need to get the whipple on the Cobra ASAP.

Oh, and a friend is looking into doing a giant dyno day on November 20th. Kind of a domestic muscle car shootout. Try to have it ready by then :)

Don't bother Sean. You will still be slower than everyone else the way you drive.

Good luck Eric, I look forward to seeing and hearing this monster!

Here are the pictures from the first day.

Awesome. :drink:

Looks like you got a nice start on it.

Ron, correct me if I'm wrong, but isn't the stock block only good for 500whp or so (not the bottom end, but the actual block)? Eric's car should be well over that I'd imagine...

That's what people say but the ones that break the block are the ones revving them high. We're building this simular to the 302 in my Cobra and are going to keep the RPMS at no higher than 6000 and only 10 PSI of boost. I figure with the 331, a little larger heads and a better cam that that he will probably make somewhere around 470-480 at the wheels on pump gas and 510-520 rwhp on race fuel.

Even at that his car will be faster than my Cobra because it will have more power and is a little lighter.

This one was running fine on 12 PSI with water-meth injection. I added the water-meth injection after melting a piston, but the block was fine. I also kept it under 6000 RPMs.
