I was wondering is the 3 extra inches worth the 500.00 ? Or are you better off using that money for somthing else?

See this why i asked the question theses are the things you find out if you ask.revperf said:Hey Mori,
Just thought I would throw my two cents in. There is nothing wrong with a great set of finely prepared OEM cylinders. The advantages that the 98" kit have are pretty vast though. I'll run a few down a few for ya.
1. Larger bore size physically unshrouds the valve curtain area and allows the head (OEM or ported) to work better. Improves low lift/low velocity flow=improved torque.
2. Sheds heat 5 times more efficiently than a standard cast iron sleeved cylinder. (Independant study at Northwestern University) Physics 101 - All aluminum pot cools down way quicker than a cast iron pot. These things are cooled with air and oil.
3. Nickel-Silicon-Carbide has 10 times the wear resistance of conventional cast iron liners. It would cost you more than the difference to tear yours down for a hone and oversize.
4. Lower ring drag coefficient by nature of the plating in the bore.
5. Proprietary, aerospace grade, high silicon content casting.
6. Warranteed for LIFE against warpage or plating defects.
Thanks for the time!
No offense intended, I certainly agree with your statements, but the figures are inaccurate as shown by this copy & paste from Rev Perf websiteGeezer-Glide said:And one last thing. Sure, the extra three inches never hurt anyone, but seriously folks..... physics tell us that a square motor makes power and TORQUE! The 98" is a 4X4. The 95" is undersized bore so you will never get the same numbers using part for part. (ie: same cams, exhaust etc. etc. in a 98" will beat a 95")
No offense taken. Thanks for the update, I was wrong, thought they were 4". My bad!! #[email protected]The_Snowman said:No offense intended, I certainly agree with your statements, but the figures are inaccurate as shown by this copy & paste from Rev Perf website

ok can someone point me where to find more info about what bore would make what c.i. with a stock 4" stroke? looking at revolution perf. web sight they show piston kits up to 4.25" can a factory cylinder be bored to that size? what is the limit for a factory cylinder? someone know the formula I need to figure c.i. from bore and stroke.. I should probably be able to figure it out but to many years since high school.[B said:Bolt-on big bore kit, 98 ci 3-15/16 bore Revolution cylinders 10.5:1 forged pistons, pins, clips, rings head and base gaskets [/B]
