There is an interesting thread about the installation of a Chevy head on a T engine... I am wondering how many of these installations there are. And how many methods are used. Performance? Problems?
Thanks for bring this back to the forefront. My project doing this has gotten stalled. Sold the mounting plate to raise funds for other things and as it was, didn't like the design. This was not a Thunderbolt conversion it was different. There were several different people making these over the years. Jern's business is being sold off.
Hi John, I have two complete JERN O/H kits, one for a model "T", and one for an "A". Bought them from Neal about three years ago, Intake manifolds,blanking plates,valve covers, gaskets, and all parts nessesary for install, Also two complete finished heads and all the instructions for both. Haven't got around to install them yet. If anyone wants any copies or any info that I have please PM me email. email@example.com Don
There was a Chevy head and adaptor plate here on the classifieds a little while ago. While I have no immediate use for it I would love to get it to hang onto before some hoarder does...
Tim, the way you worded that, it should read
some 'other' hoarder does...
I know of 2 running at this end of the world.
I have one I built on my 27 roadster down here in New Zealand.
I should add I know and have worked on a very nice Model A speedster with the conversation kit. Great sound.
What is the "up" side to doing a Chevy head conversion ? And what Chevy head is being used ?
COST! While the up to 1927 heads can be used they only have a single exhaust port and the valves were about the same size as the T. The 1928 has 2 exhaust ports and larger valves. There is an Olds head with three ports but not real common to find.
Relatively inexpensive to put together in comparison to an overheard conversion duly designed for a T block such as the Fronty or RAJO.
I've installed & been in both camps - Chev. & factory overheads so I'm clearly biased to utilizing equipment designed soley for the Model T !
i acquired one of those Chevy heads about two decades ago when I was going to "do something". Well, that never happened. The head is still in the garage. Somewhere.
One operating Chevy head conversion here in Texas also. Seems to have good speed and power.
There are a bunch of them around here.
Neal Jern was the established producer of the adapter plate and many accessories. Don't know how much of the inventory is left after the business closed. But I hear that several members with CNC capabilities are thinking of making their own. Supposed to be straight forward ...once the process is established and tested.
I would like to acquire a print for the adapter plate if someone out there has one they could copy. I have a CNC militant needs something to do.
Stupid auto-spell. How about CNC mill.
Anybody have any photos of installations, details of assembly and interesting details?
Wow, check this site out...everything but the rockers...
I just ordered a fresh set of rocker shafts and bushings, I was contemplating having to make them myself. So glad I don't have to.
Been emailing Robert, seems like a nice guy.
