Yep & you won,t be feeding it a 4oz bottle of ZZDP every oil change , that alone will make up the $650.00 in no time Larry. Enjoy Mark
That comp cam is similar to a TA 308S, although on a wider lobe center, which is unusual for a solid cam of that size. Any idea why the 112 center? I have measured the duration loss at the rocker on a 308, with .022/.024 lash right at about 8-9 degrees. Hard to compare apples to apples, due to the 112 center on that cam, but I would imagine if I put a 308 in Larry's motor, it would pick up 50-60 HP without much trouble. Torque would be similar, but rpm range of the motor goes up, and a lot of the HP increase comes from just that. It's not an rpm range I would want to go with Larry's motor. I base this on a 10.5-1 464 I built a few years ago, with STG 2 SE's that didn't flow near as well on the intake as Larry's, were about the same on the exhausts.. here's the sheet on that motor. JW
You need the extreme pressure lubes to handle the friction caused by the interface of the lifter on a lobe of a flat tappet cam. Larry has a roller cam now. When roller motors go together brand new, we just oil the rollers well and put a little oil on the cam lobes. There is no such thing as cam breakin. JW
Personally I understand the want for a hydralic cam like this. It cost several hundred dollars more but it it worth it IMO. What you have here is a 600 hp car that drives like a 400 hp car on the street. You don't have to wind it up to the Buick danger zone to achieve that power either. No cam lobe failure worry. No expensive additive every oil change. Yes you could spend a few hundred dollars less and build this much power but at the expense of driveability and durability.
Very Nice Numbers on the build! Hyd rollers rock! U get the best of everything from them , and most of all no worries of loosing a lobe, Since I went roller I won't go back!, Your roller is very close to my roller looks like, mine is 236/245 on a 112 LSA... Idles at 750 in gear and runs all day on 91 pump gas. Again congrats on the big numbers! Hook her up and it will fly!
