If I was to do a resize on my cyls would it be a worth while power benifit to go as big as I can? Also is it worth advancing cam timing on a stock engine? How much?
Thanks

Go fast her eh ?

Well, "Nothing beats cubic inches" eh. :lol:

You could shave the head a little, depends on what you are trying to accomplish. If you need to, because your compression is below 156, then go for it if you want a few more horses. However you will likely need to raise the fuel octane if you get a higher compression ratio. So much for fuel savings.

The plug-and-play method would be a 3Tech 218/350 cam or the full 222/365 race cam and +10 deg. cam gear. This changes the dynamic compression, not the compression ratio. http://cochise.uia.net/pkelley2/DynamicCR.html

From what I have read it is good to advance the timing to 8 degrees BTDC for a little more power and a little less carbon build-up.

Regarding your other post, the only way to know your horsepower would be a dynamometer test. One could speculate but that's only opinion.

Thanks Bad, ya cubes eh, hard to beat, especially back when gas was cheep. Nothin like a BB.
All my engines have good cyls and don't need to go bigger, I was just curious if it was worth the extra $$.

I have looked into 3Ts goodies, look good, plans in mind :D
Can't wait till I have time to play !

Well, we don't need to go bigger. :roll:

"I was just curious if it was worth the extra $$"
It's that word "want" vs "need" conflict that always gets in the way.
My Geo acts like a strong 4 cylinder now. I believe it's doing quality spark, breaths easy, has more dynamic compression and is less constipated. I think I want an MSD 6A ignition box and have to justify the money for used or new w/warranty. Fish or cut bait. :thwack:

At every turn I have upgraded whatever I put on my car.
