stroked small blocks in the race cars?

[1795]

Thanks for al of the input guys. My engine builder is going to be sorry he ever agreed to do the build I will have a lot to discuss with him. He reminds me of Brent, he lives in farm country, his shop started out as his garage and has slowly expanded over time. There is a local drag strip, so he does a lot of drag racers, also does some street stuff, an occasional road race car, and in addition to a variety of small block and big block Ford engines in his shop, there is a tractor engine on the bench.

I sent an email to Dan Case and asked if he knew the specs on what the 289 race cars were using for a cam and he said that in his 289 with Webers he is running the C7FE cam, which is what Ford sold off the shelf for race applications. He thought that it had a lobe separation of 107. I looked up on the web and this is what I found:

Another site said that the duration of that cam was 250, with an intake lift of .528@.050" and a lobe separation of 108.

Does this sound similar to what you guys are thinking?

Will Rick be pi$$ed that I sent you there?

He probably is having nightmares already. He actually is enjoying the build and every time I talk to him he starts off by saying he did some more research last night.

I will be doing a balancing act between what I would like to see, what you guys suggest, and trying not to step on his toes too much, as he is the engine builder and knows more about it than I do. He has a good reputation, so I do need to heed his advice, as he is the one that will be building the engine.

Jim you started off by just wanting to freshen your engine. Now after listening to all of us you are heading toward one of them $25 to 35 thousand dollar new engine. Its easy for us to spend your money. In the end it is between you your engine builder.

C7FE cam would be a big step backwards if your running a roller now. They sound good. I have one I took out of a 67 Shelby. My kids want me to put in in my Gurney Eagle engine because they think it would sound so cool. They also think it would pick up a bunch of power because it has such a mild hyd cam in it now.


Do you feel you need a bunch more power or just more RPM to carry you thru if you need it.

I am just a hobby guy that likes small block ford engines. I dont have to pay for any engine work. I do all my own work.

I agree and if I was unclear, I'm not saying that Jim should run a factory flat tappet. I'm suggesting a new solid roller with specs that correlate to the application.

I know, I was just asking if the lobe separation, lift, duration, etc., were in line with what you were thinking. I have no plans to go backwards in time and put in and old school cam.. Just helping me understand your thought process.

Yes it is easy to spend someone else's money As the engine was torn down it was apparent that some things needed to be addressed. It will be a couple of thousand more than I had planned, but still well south of $25K.

The factory cam would have been picked for factory heads and factory part combinations. Today's parts, including Dart heads, would change the specs. It could be that you would need a 106, or maybe even a 109-110, but I would have to get the head stats in front of me along with all the other parts.

I wasn't suggesting that you go back to 60's cam specs, I was only suggesting that you get away from the normal "internet spec'd" camshafts, with long LSA's.
