A buffalo’s first bowtie

Thanks Chris...I'll ask the shop while I'm writing the check this morning if I can borrow one!    

1/2" Chris? Isnt that a little big?

Not sure how close he needs to be on pushrod length- the BBC will have the adjustable stud-mount rockers, no?

Buffalo, very cool on keeping it RH. Is the custom grind a little warmer than stock?

Time out! Trouble again. The part # I put up before is for a chain driven cam, not my gear drive. I'm waiting for a call again, but the price is expected to go up?!!?

It is a warmer cam, but not a hot one. We'll see...

Not way off but there are two variables in play the pivot point, and the pushrod height. You need to adjust the two to get not only the proper preload but also the proper roller position on the valve stem.

If you have a fixed pushrod height then you can adjust the pivot point to get the right preload but if rocker is already tilted back too far towards the pushrod side because of a short pushrod then the roller end is likely to be on the edge of the valve stem towards the rocker. Too long a push rod could also side load the valve. If you want your seals and guides to last you need to both adjustments right so that your roller is traveling back and forth on a path that is centered in the middle of the valve stem.

Its all a PIA and you need both adjustments to get it perfect, one will get you working good enough most of the time. If your converting to roller lifters they are typically significantly taller than the flat tappet, non standard heads and valves can also make a huge difference. My 408 ended up with pushrods almost an inch shorter than stock no amount of adjusting on the studs would have helped that.

Guys, I got my call back and don't know what to do. I was prepared to spend a lttle too much on this, but not way too much. Here's the thing...the pressed on gear drive system that I have apparently hasn't been used in some time. At least 1 cam company would be happy to start from scratch on my cam...for $2500 and that's just too much. I can get a flat tappet cam that will fit the gear drive, but I really wanted to go roller. I can also get a roller cam for ~$1300 mentioned before...but this is only for a chain drive though, and would reverse the cam rotation.

There has to be a good solution for this?!!?

there are gobs of dual engine 454 setups in all the penis extensions, um I mean sport boats made by baja, checkmate, cigarette, etc dont they have opposing rotations these days?

I haven't done the pricing and probably don't know the details, but I'm thinking at this point to change rotation(sorry Tim) on the engine and flip the pump as Eric suggested to keep the RH drive. The parts cost for the standard(LH) conversion kit is more like $700-$1000 I think. This would mean I switch to a timing chain and then my distributer is going to be backwards.

I'm all ears guys...good thing I have the winter!

Just to clarify, when you change the direction of the engine and flip the pump it doesnt reverse the direction of the propellor to the original direction it just makes it so the transmission will still work. Forward will be in the direction the engine turns and reverse will be opposite. Long story short you need a new propellor and a new starter. Your new setup would have a standard timing chain setup and your original ignition could be used after changing plug wire order. You will need to flip over your RWP as well.

Your circ pump and alternator should make it in the opposite direction.

I have done this before and will talk you through it if you decide to go this way.    

Yep, I remember the talk about the 1:23 Got it.

I guess I may not get what I want then. I really want to keep the RH prop rotation, and I really wanted to go roller. Like oil and water...they may not mix short of the high dollar cam. I'll keep digging; I don't give up easily!

Never

$1579 from SkiDIM.

$1600 plus shipping that's rough, Eric is it possible to do any better than that price?

Have you called and Talked to Comp Cams about a custom ground roller cam?

They are the one's who will be happy to start from scratch for ~$2500. That would be the gear driven roller cam for my RH set up. I've also talked to crane and lsm.

Cam Research... Those guys are Ford Only wont touch no bowtie
