I'm thinking about installing the High Performance Camshaft for Model T, 280 Super lift and duration. Any ideas or thoughts about improved performance.

Happy motoring,

Warren

Here's a link to a camshaft comparison that one club performed:

Take a look at the re-grinds from Chaffins. Very good and very cost effective!

Whats got me beat is that so many folk talk about "re-grinds" when its obvious that the cam is a brand new camshaft.
I've always thought that a re-ground cam was a stock cam that has been re-ground....meaning that metal has been removed from the thing.
So what is it that I'm missing here.

I would be interested to hear more from anyone trying to squeeze more HP out of a T engine
and how these factors work together. It's a long stretch between the 60's Mopar performance
engines and a little ol' T.

The reground cam shaft from Chaffins or Carnegies is about $60 as opposed to $300 ++++++ for a new Stipe or similar. Rob, there are all sorts of ways to regrind the stock cam.

Burger, go down to Carnegies on Dollar Road and talk to them. Tom will show you how he runs 55 +++ in his mostly "stock" T on the Montana 500.

If I'm reading the Tulsa charts correctly, the increase in horsepower with the 280 and 290 cams was one or less. That's about 5% more horsepower (or less). Does that significantly improve a car's climbing ability?

Maybe the cam payoff comes in conjunction with high compression?? Bud.

I thought that Mark Chaffin once posted here that they offer both new cams as well as their regrind, but maybe I'm wrong.

Terry, Yes Chaffins make a new computer designed 280 cam as well as supplying reground 270 cams.
Along with bulk other T engine stuff, I've just bought one which has been stuck in Australian customs for 10 days now.

I use this saying when I want to increase HP or speed:

"To increase speed, add lightness"

Can't find the true source of the quote so credit given to unknown person.

Yes Philip that is true but more accurate is that horsepower cost money, normally lots of it. Horsepower also creates problems with things that break and things that don't brake (brakes that don't stop so well).

The data shown in Larry's cam analysis is in error. The Chaffin 250 and 280 cams have a 110 degree lobe separation. This improves the low end of the cam and does not harm engine performance as Larry suggests. The intake valve is advanced to 2 Deg. ATDC which improves the high end without hurting the low end. The result is a cam that performs well over the entire operating range of RPM and will climb hills in high gear. Our 270 reground cams perform equally as well at a lower cost.

Once again thanks to all who responded. I like the idea of using a Chaffin reground cam, as I am more interested in improving my engines torque than top end speed or horsepower.

Happy motoring,

Warren

Phillip, the quote you're referring to is from Colin Chapman, founder of Lotus.

"Simplify, then add lightness"

Warren, With our cams you get both.
