Free cam build...

The Ti valves are of some concern if you don’t know their service history due to potential work hardening. Fast closing rates (hammering) accelerates the hardening rate of Ti valves. This is an area where the slow ramp rates and timid valve spring pressures with the free camshaft will be an advantage. I would be more concerned about what block to put this on and be looking for something that could accept four bolt main caps.

We are all here because we are not all there.
I did not know you could do that.
Seems like a waste not to use the heads to they full design capacity.

Not sure why it’s a waste... with a little work they will flow in the lower 300 range and will make as much power as the stock block can handle... even with the free cam
They flow 290/300 OOTB if not really close to it.
More assumptions!
More assumptions!
It is done on most every build save a serious racer or a nut job on the street that has to have every last HP... or actually what he thinks he is doing....

I”ll get valves installed in them and post the flow...

At the end of the day this is all about what you can do with a free cam...
Oh yea I get it but that reply was for the quoted and not you.

Yeah the stuff came up for sale in Calgary which is about 1400km away from Winnipeg where I live...contacted the seller and it turns out his house is about a 5 minute drive from a good friend of mine...worked out good for him as he can just drop them off and I got a great deal on the stuff

just a historical note on Crane of that vintage from a current speed talk thread
Exactly.
Harvey {Crane}came to our shop in the 80's in his motorhome, trying to sell/Lease us his software.
I think he had it on a 286 with a math co-processor.
I sat there while ho showed me how it worked.
He started with a basic lifter motion curve, then said, if you want to make it bigger at .200", you do this. If you want to make it smaller at .020", you do this. If you want to lower the max velocity, you do this.
Being the 20 year old that I was, I said, what do you do, to make it the correct curve for the application?
The look on his face changed instantly.
I then told him, using the parameters of the engine, we design the optimum valve lift curve for each application.
He angrily told me, you can't do that. He then drove off, and never talked to me again.
I've been "Can't doing that" for 35 years since.

Man-O-Man do I hear that! Ditto and then some.

Anyone have any links showing W9’s with a motor plate and alternator and power steering pump mounted...

That's what i would do. The original engine combo i had when i bought the car had a set of cleaned up 302's with a 1.84 valve and a 320 adv 256 @ 0.050 490 108 lift solid cam. That incarnation ran the hardest of all the combos Ive tried. The torque through out the entire rev range was incredible.
Its really cheap too......
What brand of cam was that?

I was told the lobe came from a cooper mini S. Was just given the specs and told it was ground on 108 billet from a local machine shop.
This cam would be close Sig Erson 320 LHM but not sure if they make it on a chrysler core. Has more lift too.

Glad to see you diggin your heels in on keeping the cam. Most of these pushovers on here would have thrown the free cam in the garbage and run something a "guru" told them. I love your direction. This is going to be a FUN build and that's what it's all about!

I have no idea. Its a really old cam grind that's at least 30+ years old. After i have some fun with the current combo the air gap and that solid cam will go back in and see if it runs 11's

Now I need to start figuring out what parts I need to run the W9 heads on a 59 degree block... I assume some kind of offset rockers... and push rod oiling possibly...
