ah, another lesson learned. i just found a flintstone thread of somebody selling his 264 degr. cams because he didn't get it to run stationary.. so it is possible that my cams are 260 degr? :/

just a bit strange that kent doesn't use default engine-specs to inform about their cams.. the powerband on my cams is 4000 - 8000 (+??) atm while the website advertised them to have a band from 3500 - 7000 rpm :/

just emailed them back with this question because nowhere on their website it tells me to have special pulleys for the cams to follow their manufacturer specifications..

Verniers cant be used with standard management anyway due to the cam sensor pick up.

I just replied to that old thread.

I fitted the Piper bp285 cams to my tb'd c16xe, and got the pistons pocketed to be on the safe side, then got the head skimmed to make up the compression and some.

As far as I'm concerned my old engine in my Nova was perfectly drivable, and was at the apex of cost/power curve.

For your possible interest my spec was:

C16XE
Jenvey 40mm Parallel Throttle bodies
DTA E48 EXP Engine management
Pipercross dome air filter
Ported cylinder head matched to inlet and exhaust manifolds
Kent Cams Vernier Pullies
Piper BP285 Fast road cams
Pocketed standard pistons
Head skimmed 25 thou
Deseemed rods
ARP con rod bolts
SBD cam belt rollers
Lightened Flywheel
Balanced bottom end
Bosch c20xe cream injectors
FSE Black top Fuel pressure regulator
FSE Escort Cosworth Motorsport Fuel Pump
Janspeed 4-2-1 Exhaust manifold
Custom 2 mandrel bent stainless exhaust

One of the main factors ultimatly of power and drivability is the map, so be careful with who you chose to map it.

Ported cylinder head matched to inlet and exhaust manifolds - mate did mine, but expect around 300?
Kent Cams Vernier Pullies - 150
Piper BP285 Fast road cams - Mine were 2nd hand, new - 300?
Pocketed standard pistons - 40?
Head skimmed 25 thou - 25
Deseemed rods - mate did mine, cheap with a flap wheel.
ARP con rod bolts - 65
SBD cam belt rollers - 100
Lightened Flywheel - 50
Balanced bottom end - 70

Roughly what those bits will cost at a guess. Plus the cost of an engine rebuild if your not doing it yourself.

what power was your engine putting out then? with all that done? im looking for around 180bhp, and was told when i bough the car that all it needed was some cams and vernier pulleys to achieve this?

It made 199bhp, although I suspect that the rollers weren't very accurate, so I'd say around 180bhp odd.

To change the cams for some with decent lift will require the pistons to be pocketed.

You may well get 180bhp with just a cam change, have a look at the SBD kits, the difference between the 164 and 184 kit is just a set of cams.

Thats the nature of engines mate. I was just using it to emphasis the difference a pair of cams can make, and whats needed to use them.
