Re-chambered Head (Head Mod)

[wwholden]

I have two re-chambered heads that I have machined. This is a toroidal style chamber (low-mid range torque) thats approximately 20cc's. This can simply be bolted on, no jetting or tuning required. Here's how I am selling them. $40 for the head if you ship a stock head (core) to me. If your not sending me a stock head in return there will be a $20 core charge added. Buyer pays for shipping. It will be sent USPS Priority Flat Rate Mail ($10). I currently have two. One is completely sandblasted and one is not. The sandblasted one will is $10 more. I can also powder coat it for another $5. PM me a phone number for the quickest response.

Can you explain the reasions for that chamber design ? Haven't seen one done like that. I'm just wondering about the flame travel and compression.

Looks nice. Thats a DEEP combustion chamber...how many CC's is the chamber? Whats the width of the squish band? Have you tried the "Hemi" design yet? Keep up the good work.

I can vouch for the toroidal chamber when it comes to producing a lot of power on a stockish motor with a pipe which favours low/mids.

I fitted a wwholden head last week and am in the process of testing it.

In the next few weeks I will be removing it to see what the resusts of the gas flow picture.

My old head will be machined with a hemi cut and then I can make some comparisons.

I saw an interesting design the other night. Can't remember the name of it, but imagine a cross between a hemi and a tori. Or flat top hemi.

It's a cool design that I would like to try out. Is there only two available or is this an item that you will keep producing for sale ? Moneys a little tight right now do to a needed car repair. I would like to be able to buy this at a later time.

Stay tunned Ill be working in a Hemi chamber here soon using CNC equipment.

I have two at the moment. I have been told by AWK08 that after these two sell I will no longer be able to advertise them for sale..... per the "Marketplace Rules"

20cc's at the calculated 50% bore (44mm). I have not done a HEMI design yet because I do not have a radius tool. However I am designing a program for a CNC lathe to cut the chamber.

 

[joeak47]

You don't need cnc to cut a hemi chamber.

 

[Larry's Shee]

Have you actually CC them? or is it an estimate?

 

[joeak47]

This is also why I'm asking about the CC's too. I've made quite a few toroidal chambers,and by looking at the depth of your cut, that chamber CC looks closer to 24cc,or possibly more.
What do they CC at exactly? This is important. Just a need to know.

 

[wwholden]

Its at 20cc's. I forget what the decimals were.

I bought a blaster the person told me it was bored out to accept the biggest piston the stock sleeve could take. so im guessing its a 68, would this work fine with that? I was planning on getting a big bore kit aswell and a 4mm crank, would this be good to have for that application or not? if it is im interested in buying.

Yes the head can be machined to a stock cylinder and accept pistons from 66-68mm. I can also machine them for BBK cylinders too. Either way its a huge improvement over stock. PM me if interested.
