Ethyl Returns as a Ford

[wrp]

I'm going to build a 427 for my C3 Corvette - my heart (and my pocketbook) wants to build a BBC based motor - but my brain says "go with the strength of the LS cast-iron block".... so watching both these builds is of great interest to me.

I've been thinking about a good set of forged flattop pistons and a 4.1 stroker crank to make the LQ9 a 427. Block is prepped and ready to go with a 4.010 bore right now but I haven't gone for the rotating assembly yet, except for the custom TSP Diamond Pistons which are a -28 cc dish.

Not sure if we are splitting hairs? but that would be a 414 ci. You would need a 4.071 bore with a 4.1 stroke to get 427. Love the car I am sure it will fly!

You are correct. I had read a recent magazine article taking about making a 427 out of an LQ9 using a 4.1x stroker crank. I was shocked to see how much LQ9 blocks are going for. Car Craft was claiming a 4.125 stroke and a 4.060 bore would get it there.

it's funny, everything I'm building right now is in the 427 neighborhood (2 motors, a Buick and the aforementioned Corvette 427).

So what do you think about bore v. stroke? with the LS, the stroke is actually longer than the BBC...

[Russell]

According to the calculator in my Garage buddy app that will get you 427. Can you take a LQ9 block out to 60 over?

Can you get a 4.226 stroke to fit? that will also give you the magic 427 with the 4.01 bore.

Not suprised about the length of the stroke being longer. Not sure about the 4.226. What I would really like to do is build airon block 5.3 using the 3.15 stroke and the same bore as the COPO. Now that would be interesting. Everything is here, its all laying around the shop. Hope to have it together in the next few weeks. Got the turbos back from Work Turbochargers

We got the motor sitting in the car today and got the Vic jr back from Specialized Performance Coating. Was really pleased with the way that turned out. Specialized Performance Coating

She's starting to come back together. Brian is making good progress.

Closer and closer, guess the hot weather caught us.

Welp we worked on Ethyl's cold side plumbing today. Brian did an amazing job on the welding. I am thinking we just need to get the Co2 charging system in the boost controller then boost the sucker to the moon. One thing for sure, they ought to hear the explosion in Oklahoma.
