Scott,

I will be in the market for a kit soon. Just waiting to see if I need a standard or shorter kit if the block needs alignment honing.

Same here! I'll need 2.

I will have a standard length and a .004" length timing set ready in a few days.

I have been asked several times what I think of the bronze bushing timing sets that are on the market now. Well here is my 2cts....The bronze bushing is a great idea, but the bronze that is suppose to reduce the wear and friction is on the wrong side of the cam plate. At wide open throttle, the cam is trying to push foward under the load from the oil pump drive shaft and the distributors helical gear. Using a roller cam increases this foward motion because the cam lobe is ground parallel to the cam C/L and on center to the lifter bore for the roller lifter contact. The standard flat tappet cam has a slight offset to it to do 2 things, spin the lifter and to keep the camshaft in position. With a roller cam this is lost and the cam is able to move more freely that the flat tappet style. When we dyno tested the roller cam plate, we were shocked to see that the new cam plate had a .004" step in it after only 13 pulls. Some thing else to consider.... Have you ever put a timing light to the engine while running at 1500 rpm and noticed that the "mark" is moving around a little? That is the camshaft endplay at work. The cam is moving back and forth and changing the timing ever so slightly. With the roller cam plate installed, I set the end play at .004 to .007" to control the cam endplay. Controlling this variable is on of the reasons for the increased HP and torque on the dyno test. The timing stayed where we set it and the friction reduction from the bearings came together to make the extra grunt. The roller bearing camplate has bearings on both sides to hold the cam in place and to greatly reduce the friction.

In other words, the bronze bushing only works when you let off the throttle. The roller bearing camplate also works when you let off the throttle, but it really shines when you are at w.o.t. and that is what counts!

thanks...Scott

Hey Scott. Your timing set is the greatest. I really like the ability to degree the cam in without offset keyway's to deal with. Your product rock's Thank's again for developing a great product for us Pontiac guy's. Thank's Rusty

[riceslayer]

hear that rusty. thanks scott for the awesome product. i wonder if you could do a gear drive if i send you one. every roller cam needs one of these.

[simsb52]

It can be done. A little more costly though!

I have a .004 and a .010 ready to go if anyone needs one.

Thanks...Scott

[simsb52]

I have a .010" rollmaster ready to go if anyone might need one.

Have a nice day! and thanks for the business....

Scott

[simsb52]

I have a .010 set ready to go

Thanks for the great comments.

[riceslayer]

hey scott, could you do a pete jackson if i send it to you?

[440GP69]

Hi scott, I have a 535 i am building, Should i start with a standard since its a brand new IA2 or should i go .005 under, or wait and measure?

[riceslayer]

great product, scott. you must be a busy man.

[simsb52]

440gp69, I would start with a standard length. New block, It should be right on the money as far as length goes.

Riceslayer, I could/would, but I am in the busy part of the season as far as the shop goes. It would take some time and considerable money for the gear drive. Just trying to be honest about the time frame. Heck, I still owe a couple of drive shafts to one guy that has been patiently wait on me (will get to them in 2 weeks). Really!

Anybody need a .010" set? Still have one ready to go!

Thanks for all the great comments....

Scott

[riceslayer]

man no rush, and i have the gear drive. just curious but remember i can sell some down south for ya when you get spares. thanks scott, rs

[Murf'sDad]

Scott:

Considering how busy you are, what the time frame for a standard length setup shipped to 04730?

Thanx, Stewart

[440GP69]

And how long befor a Standard 9-key Billit RollMaster set could be made for me? Thanks

[simsb52]

Turn around time is usually around 10 days from date of payment ($265). Payment includes shipping to the lower 48.

Thanks....

Scott
