Decided to go roller

Dave,

Let us know how your roller cam compares to your previous flat-tappet grind.

I am going roller myself but changed from Hyd. to Solid; can't use the trick Hughes lifters so I posted them in the classifieds here.

Are you using 1 5/8" headers with your package?

Gary

Yeah I have the tti 1 5/8" early a-body headers. I noticed yours on sale soon after I bought mine. I'll give a comparison low down for sure.

Brian at IMM ENGINES has some SOLID ROLLER LIFTERS that will drop in an LA Block!! Oil thru also to keep pressurized oil at the Ball & Cup which is a huge plus!

I chatted with Brian and he gave me the same recommendation as Hughes as far as the cam choice for my setup. I would not hesitate to use Brian for any future builds or work to my heads. The Hughes lifters are the oil through type :-D

You'll love the roller cam. Those specs are not far off from mine. I have a custom ground hydraulic roller with .530 lift and 230 degrees at .050.

Surprisingly, it idles real nice and has good street driveablility. Only 5" of vacuum at idle though. Not a problem for me with the four speed and manual brakes...

In my combo, it made 458HP on pump gas, so it's enough cam for me.

Wow that's some serious HP. You running eddy heads? What's the rest of your combo.
