Keep in mind that once you put the smaller crank pulley on, the distance between your timing pointer and the crank increases enough to introduce error as you move your head around while siting the timing marks with the timing light. This factor only makes it more challenging to accurately set the timing after the pulley install.

What to do? Set the base timing before the install. Mark the distributor and housing at 15* and 19*. Use these marks for future timing adjustment -- they probably will be more accurate than any marks you can put on the smaller pulley.

If you want a backup, transfer the marks to the new pulley. Then check your base timing again and see if the marks are accurate. Make notes about how the marks calibrate and how to position your head for consistency.

IF these come un marked i will install all 3 pulleys minus the crank pully........do all my tuning with the stock crank pulley. then simply swap pulleys once i feel everything is as i like.

there is a thread were the primarys were measured and placement were compaired to the hot shot gen 5. while similar they were differant.......if you insist on still saying it was copied you could say the gen 5 was looked at and "improved" apon.

this same argument is used with the brian crower stage 2's against the JWT S4's..........this instance is alittle more blantant because its quite easy to take lobe measurements than it is to make a jig to compair a header.

i dont think anyone will deny the fact the hot shot gen 5 wasnt playing a role in the construction of the SSAC header.

however the fact remains that i just bought an SSAC header off ebay, 2.5 inch secondary, ceramic coating on top of the stainless steel (most likely paint) for $106 shipped.

i understand what you're saying. and honestly, it's a hell of a price for what you get both SSAC and BC.

but is there any R&D into their products? any proof that the product is actually their design? hotshot went out of business because people were ripping off their designs and selling it for half the price.

just sad to see.

and JER. i've sat there and listened to performance industry business owners FIRST HAND and understand that competition is what makes the world go around. but when people are stealing other peoples' designs, that's just wrong. knowing it's wrong and not supporting companies like that is called having morals. i'm glad that SSAC has grown the balls to make their own designs and IMPROVE on other people's designs. that is competition. but just stealing it is just BS.

i think that if a company is really concerned about their design they can either patent the design. or have a market for customers that arent looking to spent top dollar. the whole reason for patnents is so that noone else can take the design and use it as their own.any copmany that doesnt patent or try to patent their design isnt really worried about people copying it

There is never any winning at this arguement.

patenting is not cheap. and we would end up paying for it. which would jack costs even higher. and if it is patented and someone copies it, then there are court fees. and delay times for everything. etc.

i agree with you. it will never end. i was just defending myself when you said "don't just quote other people unless you have first hand experience."

I know, no worries.

Since the 4 Piece UR pulley set is discontinued cant you run just the UR Crank pulley and combine it with the OBX accessory pulleys? Seeing as the UR Crank pulley has the timing marks and it IS the important pulley... So you only buy the UR crank pulley then buy the OBX set and just use the WP, PS, Alternator pulleys.

Are BC cams regrinds? I think I read that somewhere. But then I read they were made from new cam billets
