Dose any one have way to check this on a computer or something. If so here is my specs I think would work for my up coming build.
- 427 big block
- merlin 345cc heads
- 12.8to1 comp
- comp cams Hyd.roller 248/254@.050 lift .560/.580 max lift 110deg.lob sep.
just get close.
cam is to small
yep
that is the bigest comp cam offered in PAW that is a Hy. Roller. How big should I go.
your heads are big cc on the intake port you will have to run it pass the cam i would not run the hydraulic rollers are heavy the will be hard to keep them on the cam it hi rpm in the mud try some thing like 685 /685 269/279 @0.50 on 108 or 712/715 278/288 @0.50 on 108 if you run 4 1/2 crank and if you must run the hydraulic try a custom howards but i would not run the hydraulic roller at hi RPM or you will be sorry
what kind of cams are those three you just said solid or ? I dont care if i run the hy. I was told they ran smoother.
the two are soild and the dura on any thing soild or hyd is going to run choppy the valve train noise will be less with hyd no running lash
ok but dosent the solid cams were out lifters faster.
they are rollers they are made to roll . hyd or soild with not the rigth spring pressure can make them junk and a lot of things like not washing the new roller out in thinner and blowing them out and setting them in clean oil before you stick them in
so what is the diferance. dose the solid build more power. I always thought the rollers would spin faster and smoother than the noisy solid. All the solids I ever heard were noisy like a diesel.
the cam s that i give you are solid .soild rollers they have no parts in them like a hyd roller. solid are lighter and no valving in them which helps at hi rpm
Joe, here's an example of a cam that Pat is recommending....

a hydraulic roller with about the same timing will float the valves at 7,200.
here's one step milder...

its just that these cams seam huge. A big block at 4800-8200 wow. I never pushed my small block that far. But it sounds like you know way more than i do. All you guys have helped alot and Iam shure it would sound mean runing. Thankx alot for the web resalts that helps alot to, Techinspector1.
So if anyone can check my hp here is the new cam I will check with the other spec's. crane cams solid 278/282@.050 lift 714 max lift. Lets try that one.
