SE, Hardyheads is correct huge difference between your SE260 & the Tman 625. What is your CR & CCP at now?
The two cams are miles apart in cam timing ....... Intakes closing 41 vs. 60 just for starters. Your compression is going to jump way way up with the Tman 625.Your pk tqe will come in about 600 rpm`s earlier. The TM 662 -2 or 3 would be better in your case. In closing is 51 and 61 TM662-2 still may have too much compression with out getting into the motor. TM662-3 will have just about same compression as the SE 264. The WT46 will suprise you.........still ,ya got to go into the heads and readjust compression.
Well using the calculator on bigboyz site & your CR at 10.5 that implies your CCP is about 185 now, the Tman625 will push your CCP up to about 202. That's about 5 less then mine but more then most folks want. My CCP is at 207 but I'm running 103 & using my compression releases religiously, Yooper cables & just installed a new Ultima 1.75 starter & I'm still hoping that all that combined is going to make mine manageable... Just thought I'd share some valid info for you to think over, most here would want the CCP you have now. Not that it would not pull like a bear and run great with the proper tune, just sayin.Mine will not start unless compression releases are used if motor is hot it will not turn over at all
How the hell can you even calculate CCP without making a lot of ASSumptions about his engine particulars??I think that throwing out unfounded or unverified information is what gets people into a lot of trouble and then, where are the people that sent them in the wrong direction? longshooter
662 is a lot of lift. The whole valvetrain needs the geometry fixed to run that effectively and likely with a 1.90 valve intake it's a waste.
Well, I am going to bring up the WT26 becase of the 50 closing and the 248 duration, Low lift and super quiet.One thing the 26 has taught me is you do not need high lift for big power. High lift is hard on the valve train and longivity of the engine. I ran the Wood 8 in my 114 so I know 248 duration is plenty for the 113. If the exhaust ports flow well it is a prime canidate for that cam.

They are assuming a 7.667 rod (I'd doubt anything else though Jim's had a 7.600 for a while), std atmospheric and know the intake close. What else do you need?Max
