Trying to get a Hydraulic roller camshaft ground and NOBODY has Pontiac cores available, and no ETA on any too. Anybody have any leads? I need one for a customer I'm building a 525' engine for. I need something in the 250ish intake and 260ish exhaust range. I can get solid roller cams but I'd rather go hydraulic if possible.

How about buying a used solid roller of more lift and duration then you need and then getting it reground?

Have you tried Jones cam designs?

Have you tried LSM?Tom

May try giving Paul a call at Koerner Racing.

Give a call to Tim Goolsby directly at Bullet Racing Cams, ext 102.. He has repaired and re-ground many cams. If you find a core that needs repair it depends on damage, depth of hardness and profile. The price will be right.
Personally a few years ago I had Tim regrind a damaged solid roller cam for $157.50 + freight..

He's crazy expensive

Erson has them

I got the same answer yesterday trying to order a cam. I deal with George at Clay Smith and he told me he used to get cores by the pallet and now they are only coming 10 to 20 at a time.

Fairly recently LSM had some mid 250/260 .400 lobe cams ground and in stock. I don’t remember the exact specs.

Jones didn't have any. Also, when I spoke to Bullet they said they couldn't grind a hydraulic cam profile from a solid cam core used or otherwise.

I'm pretty sure I'm going to go with a solid roller cam instead. I spoke with multiple Pontiac racers at the Sick Week race today at Gainesville today and they all are running solid rollers. Driving them hundreds of miles too.

Dont give up on LSM,they did a RA V cam for me.tom

I would really love to know why Bullet said that gods used solid roller could not be re-ground into a hydro roller?
Did they give any explanation as to why that is?

[Don 79 TA]

what about a mild solid roller profile with the hyd lifters?

That doesn't give me a warm fuzzy feeling, lol. 100's of miles isn't much for a street car. I've noticed most of those guys running drag and drive events are also lashing valves twice a day to help them live. Basically tightening them up to near zero lash for the street drive, and then opening them back up for the race. That's not really conducive to what I'd consider a street car, nor would I want to go through all that trouble.

But hey, if guys want to go through that all the time, have at it. It's fun to watch but those guys really torture themselves to make those "race" cars survive.

Dad did the solid roller thing on the street, Tony spec'd something that was supposed to be soft on the valvetrain, and only needed 240lbs. on the seats, then used Crowers (very expensive) pin oiled rollers, and was a tight lash setup to start with. It lasted about 5000 miles on the street before a lifter went south. Not even remotely interested in solid rollers anymore for a street car.

OK, I got a hydraulic roller from Mark at Luhn Performance. He had one in stock that was pretty much the specs I was looking for. Also ordered his oil pump for the engine as well.
