Re: Camshaft
I have been using the Chaffin reground 270 or touring cam in both of my cars. Very satisfied.

Re: Camshaft
John, from your experience do you find that the 280 gives you more low end torque than a stock cam?…. Where I live is quite hilly in Pennsylvania,
And I’m looking for input on it would help my 27 tutor climb these big hills….

Re: Camshaft
Are these reviews of various camshafts in engines were they the only modification made? Low/high/Z head, pistons, valves, carb, etc?

The past is a great place and I don't want to erase it or to regret it, but I don't want to be its prisoner either.

Re: Camshaft
I prefer the 250 for both low and high rpm performance

Re: Camshaft
Thanks, was exactly what I was getting at. Its not just 1 modification that influences a performance improvement.JTT3 wrote: ↑Tue Oct 18, 2022 2:59 pmFrank the 290 is in a 27 roadster with HC pistons, SS valves, stock head & Stromberg OF rebuild (RIP HOWE). If they were available at the time I’d have added a 7.5 DMc timing gear. The 280 style were in early Ts, reg. Aluminum pistons, SS valves with seats & 5 balls.

lso I am familiar with the TULSA website for performance improvements
Good starting DIY hints (disagree with 12 volts) but the rest is easy https://mtfctulsa.com/Tech/fredslist.htm

Re: Camshaft
More compression will get you more power across the engine's entire speed range. More cam lift and duration will get you better power at higher engine speeds. A stock or mild performance cam will generally give better low speed power and response.
