427 Tunnel Port Help! Need Engine Builder!

[FIA-ERA]

Thanks Brent!

I purposely didn't get the crank and rods that was offered with the motor as they were not the original and were, well pretty worn out. The crank was a "grooved journal" and the rods resembled LeMans rods at one time . I'm concerned with staying around the stock 427 bore because of the thin walls. The stroker kits we can talk about more but your thinking the same as me. The hydraulic roller is your call based on our discussions. I'm glad to hear of some good rocker stands are out there as I haven't found much along the way for TP's.

The single plane four intake is the one that I don't have (Nascar version). I do have a cherry 2x4 single plane, a 2x4 dual plane(GT40 style needs slight repair, with "Diamond tubes"), another 2x4 single plane with "oval tubes" and the 1x4 dual plane (pretty slick but weird too). I hear stories all day that these motors, when done right, are just killer. But you MUST have the cubic inches to let them breath down low.

At the end of the day I've always been told, take you parts to the engine builder and let him decide what to do, not you. I'm trying to find that faith if you will .

Thanks! Matt

I don't think I necessarily agree with that. Just in the same way that you wouldn't just hand a home builder a pile of 2x4's and say, "Build me something...", you wouldn't hand an engine builder a bunch of parts and say the same thing.

I'm looking through my email list of some current customers right now.

I'm building a 408C for a customer right now. It will be getting its own magazine article in Modified Mustangs & Fords magazine. He and I have sent 87 emails back and forth, pertaining to his build.

A customer that's getting a 410W short block: 61.

A customer that's getting a 482FE all aluminum FE: 295...hahahah (that one's an aberration, he's in France, and he has had two engine projects going on at once)

So, with that being said, communication is key.

Dual plane intakes can be made to perform as well. My 482FE engines with Performer RPMs and ported Edelbrock heads will make 580-600hp.

With the intakes that you have, I would either do the 2x4 single plane (which would require a little more tuning attention on your part), or the 1x4 dual plane.

Tunnel Ports are like any other engine: cubic inches makes the hp/tq curves broader. You can make horsepower and you can keep a broad torque curve as well. You essentially have 3 crankshafts available to you: a 3.98", 4.125", and a 4.250". That would be around 450 cubes, 468 cubes, and 482 cubes respectively. In a heavier car, such as a vintage Mustang, I personally would go with the 4.250" stroke and let the engine make gobs and gobs of torque.
